Helping people with computers... one answer at a time.

I have two computers, on a laptop, and one a desktop, they are connected wirelessly through a network hub, that's not a problem, but I have an estimating software that requires a wired connection between the two computers, Tech support has explained to me that this is due to the high volume of data that is transferred between the two computers, much to large for a wireless connection. Well, I have a ethernet network wired throughout the office, and both computers have a nic card, so my question is, is it possible to have two network connections on each computer, one through the ethernet wiring, and the other trough wireless (this one connects other computers for file sharing and internet)? Do i need separate workgroup names for each network connection?

It's definitely possible to have multiple network connections to the same computer. But in order to make sense, they really need to be different networks. Otherwise you might not get the results you're looking for.

By different networks I mean ... well, different networks. Different collections of machines.

Here's what I mean: you current have two machines, A and B, that are connected to a wireless network. I presume that you can, for example, copy files between the two machines today. If you connect both of them to a wired network, in addition, then there are two paths to get between the machines: the wireless connection and the wired one.

How does Windows decide which to use? Well, while I'm sure there's an algorithm behind it, the best way to think of it is that the first time the two machines try to talk to each other, the connection used is selected randomly - it could be on either network. From then on (I believe until both machines are rebooted, or their cache of network information is flushed), the conversations between the two machines happen across the single network.

In your case if they happen to choose the wireless network, then you haven't solved you problem.

Now, if the hardwired network is a different network ... meaning that machines on the wireless network cannot connect to machines on the wired network, then adding both machines to the wired network may work, but only if you remove one of them from the wireless network, so they can't "find each other" via the wireless path.

But my question is this: if the two networks are really the same network - meaning that you can get to all the same resources using either the wired or the wireless networks - and you need to connect to the wired network for speed - why stay connected to the wireless? Clearly you're tethered by wire, so the machines certainly aren't mobile.

I'd simply avoid the entire issue and disable the wireless adapters in the two machines, connect them both to the wired network, and be done with it.

You either need to replace the hub with a router, so that TCP/IP addresses can be assigned properly, OR you need to install another network protocol, like NetBeui, but I'm not sure the games will work with that.

Basically I'd use this article: but without the internet part.

I have a problem at work, im the only guy here, with a better knowledge of computers and networking, hence getting lumbered with all the bits and bobs. We currently have 2 offices, both next to each other. Each office has its own High speed I/C. We need to combine the 2 offices together on one LAN, but each office still needs to use its own I/C..... The Only way i can think of is tp put a second ethernet card in each macine, and set up one side as the internet with different internal IP's and the other for the lan. If that makes sense! Its a bit over my head, so any help or advice would be immensely appreciated.


July 11, 2005 8:40 PM

There's no really simple solution that I can think of. Perhaps someone will chime in with an idea. My approach would be to connect the two offices with a high bandwidth ethernet, and then have them both share a single highspeed internet connection.

July 12, 2005 5:17 AM

Your two internet connections on two lans should be fine when you wire them together.
The setting which tells a PC where to look for the internet is the "gateway" set up two different gateways and point each computer at the one closest, then interconnect should be blind to the user

I have wireless connection the labtob is connected to it ... how can i make an ethernet connection between the labtop and the normal PC whereas the Pc Does'nt have wireless..

that means Internet-->wireless-->labtop--->wire/ethernet Nic card--->Normal Pc

thanks alot for everyone tried to help

To follow-up on the original question:
If both the wired and wireless networks are the same network, and you want to use wireless most of the time, but wired when needed for a special purpose, then simply use Windows to enable/disable the appropriate network connections on each computer as needed. That is, while using WiFi, disable the ethernet network connections. When switching to ethernet, disable the WiFi connections and enable the ethernet ones.

Hi all!
I have two systems data(Local software) and Internet. Also each system has separate network. Hint(I am using static IP addresses for both). How can I use one Network line and at the same getting both data and internet to clients. Client side I can use two NIC adapters, but how should I configure switches or routers or hubs? And advice on switches or routers or hubs to use. Now I have different brands.

I have an Ibm T21 with a wired connection to my,Earthlin Dsl account and a new Dell inspiron 700 which connects to my dsl account with an onboard wireless card. Basically all I want to do is be able to type a note on my dell send it to the ibm using my netgear router so that the ibm then prints it out on the printer that its connected to. All The "its easy " instructionsIve recieved have not worked. What am doing wrong?

July 31, 2005 9:25 AM


I have 2 computers that are linked together with a wired network using a cross-over cable. Now I also have a wireless router that connects me to the internet. I am not able to wire my computers to the wireless router at this time since the computers and the router are in separate rooms and I don't want to start drilling holes.

My question is, instead of diabling one network and use the other, can I have both of those running at the same time?

For example, I'm doing a high volume transfer between the computers, but also like to keep my Internet connection active.

Thanks so much in advance.

This is somewhat similar to the above issues, but also quite different in that I just have one computer that I want connected to two networks.

I have a home office computer that is connected to my employer through one network (using Frame Relay at 56Kbps). I also have a cable modem (RoadRunner) w/ wireless router for my personal computers. I would like to also connect my work computer to my RoadRunner connection.

I need to keep my work connection (Frame Relay) because my company has a tight firewall and doesn't use VPN, so this is the only way into the corporate computers.

I would like to use my RoadRunner connection to view web sites because doing that through my company's 56Kbps frame relay connection is excrutiatingly slow.

I only have one Ethernet card in my desktop, but would be willing to purchase a second card if necessary.

Also, if I get two networks connected to my single computer, it would be helpful to have a way to determine which network to use. For example some web pages are on the company Intranet and I must use my work connection.

Any suggestions?

Thanks in advance,
Kevin Kaiser

Pete: I'd be tempted to replace that crossover cable with a hub or switch, and then get a wireless bridge which is essentially a wireless adapter for the hub. That should allow your two machines to talk to each other through the hub, and wirelessly to the internet.

I have a question. I have a sheriffs dept as one of my customers. They have 2 internet connections currently. One is standard DSL and the other is a slow T1 through the state. The T1 connection allows them a private network called the Criminal Justice network which they can run drivers license, etc. For them to use the T1 they have to have specific IP addys etc, and for the DSL it is DHCP. My question is can they be set to use the DSL for high speed and also be setup to use the T1 when need be. Both internet connections are on the same network.

I have computers connected to server through a network switch and a router. I have our own software system installed on server and accessed via the network. I also have Internet connection through the same router, that's not a problem. But when I reset the router the internal network also stops. I want to split my network, so if I reset or stop router, it doesn't effect the internal network. I am using Windows2000 server as application server. so is it possible to split my network without effecting the internal network?

I have two laptops, one Mac iBook OSX 10 (Tiger) and one Windows XP Dell. I currently have them networked just fine using a wireless hub, but I wanted to know how I could connect the two without the hub, say if I was at a different location. Of course all of this is wirelessly. I have been able to join other ad hoc networks, but I can't seem to be able to create one...

October 20, 2005 12:00 PM

Hello. We have several PC's. For some random reasons, they access the internet via different ISP's. Group 1 goes via DSL and group 2 goes via a cable modem. Group 1 goes through one router and group 2 through another. My problem is that I would like to network group 1 & 2 together -- without affecting their method of access the internet. Any suggestions or guidance would be much appreciated!!

In answer to the wireless and wired connection.
Assuming Windows XP.
Disable the wireless connection on the laptop in the network properties and wire the laptop to the desktop directly with the nic cards.
Then in the network connection properties sheet on the desktop, select the two network connections and "bridge" them. That creates a wired subnet to the laptop and keeps it connected to the main network. The laptop can then be disconnected from the wired connection and carried around by just re-enabling the wireless connection in the network properties when needed.

How about setting up your Wireless connections on each machine with TCP/IP as usual, disabling NetBIOS over TCP/IP. Then on your Wired connections, add IPX/SPX protocol/NetBios and remove the checkbox from the TCP/IP box.

Theoretically, you machines could talk to each other and file share over the wired/SPX/IPX/NetBios path - while connecting to the Internet viw the Wireless TCP/IP protocal. - Thereby protecting your filesharing from wireless snoopers and allowing greater speed between computers where needed.

I currently have 7 rooms in my home wired for INTERNET. I use cable and have a linksys router. However, my kids are in high school and the oldest just started college and now have laptop computers with wireless capabilities, that they want to use around the house. The house is 3000+ square foot and I have a home office that sends large amounts of data over the INTERNET, so I don't want to give up my wired connection. Can I hook up a wireless router to the router I currently have so that we have both wireless and the hardwired connection?

December 27, 2005 8:46 PM

Actually you can just add a wireless access point.

I have wireless connection through a router at home which enables my laptop to function adequately. At work I have a phone line and I want to use my wireless laptop there. To connect at work (self-employed) do I need a second router and how would I connect this to the phone line if it is a different number to my home so that my laptop has access to the internet?

I have a wireless/wired home network using a desktop (XP SP2 Pro, wired only) and a laptop (XP SP2 Pro, with both wireless and wired capability, but used wireless only) through a Linksys router, with broadband Internet. While for convenience I use the laptop in wireless mode, there are areas in the home distant enough from the router that wireless connections are poor or non-existent, and I would like to connect the same laptop through the wired ethernet connections in those areas. I've cannot make that work. Can it be done and if so, how? Thanks, Dave

Leo A. Notenboom
January 10, 2006 7:17 PM

Yes. By just plugging in the network. I do it here all the time.

I'd need a lot more specific information ... when you say you can't make it work, what happens when you try? Are you certain that the network you're plugging into is, in fact, connected?

I have DSL Wireless router in my home. I also have about 8 machines hooked up to it. One with a cable (sits next to the router) and the rest wirelessly.
In my basement I work with different machines all the time. I do not have a lot of spare Wireless USB antennas, and when I do, they are not all compatible with the hardware (such as HPs).

I would like to add a second router in my basement but to be used as an extension of the one upstairs one, and use the hardwire 4 Ethernet ports in it to connect these desktops to my network. Any ideas? Everybody is in the same network, just need physical drops downstairs for these desktops...

Thanks All!

Leo A. Notenboom
January 11, 2006 7:13 PM

What you really want is a Wireless Access Point ... wire that to one of the unused ports in yoru router and you should be good to go.

You can do it with a wireless router, but it's difficult to configure things such that the machines on both routers will see each other, and you could have problems accessing the internet due to double-NATing.

January 12, 2006 7:31 AM

I have created a wired Home network, accessing the Internet through a Broadband (DSL) router. One machine is connected through this network via VPN to a corporate network. The other machines are on a home network. Is there any way for the machine connected to the VPN to be able to access the Home network simultaneously? All machines on Win XP Pro SP2. Tried to use the home networking wizard, but got the error that "This computer is already connected to a Network" on the VPN-connected machine. If I could do this, are there any security risks to the corporate network?

January 21, 2006 7:20 AM

Like Carlos, I would like to connect two wireless routers (Netgears) to each other. Can anyone forward me a reference on how to configure this difficult proposition?



January 25, 2006 9:31 AM

I have a laptop with wireless card. (also it has cable ethernet)
I have a cable connection adsl(in Turkey adsl is 256kb). I am directly connect it.
And my friend has wireless network (which is adsl 512kb. I want to connect it in the same time. Is it possible?
I can see and connect it but I can't use two network in the same time.
For example my own cable connection speed is 25kbps and my friend's wireless connection speed is 50kbps. If I can use both in the same time my speed will increase to 75kbps. How can I do this?
thank you

February 6, 2006 2:54 AM

Okay, I have a wired LAN 192.168.0.X in my games room, which connects through one PC which also has a Wirelss card (DLINK) in it to a Wireless ADSL Router (DLINK)and therefore to the Internet.

I also have another PC that has a wireless network card (NETGEAR) in it as well what I want to be able to do is two things.

1. Setup all the other PC's on the 192.168.0.x LAN to access the Internet via my PC if the primary connection (MS Intenret Sharing) is taken offline. What settings would i need to have on the PC's?

2. As the Netgear wirelss card is flakey at best (WG311v3) on XP SP2 I would like to be able to have my PC switch to the 192.168.0.x LAN if it loses connectivity on the Wireless LAN.

Wireless LAN is 10.0.0.x

When it comes to this mix I'm lost.

Hi, I have read through the articles, but cannot seem to find a solution to my question, albeit similar to some of those posed.

I have a hard wired network with address range to 250 with subnet mask of I also have a Wireless network with to with the same subnet mask.

I want to "see" all the machines on both networks, so I have accepted the DHCP settings allocated by both routers and can surf the internet from either connection. What I want to do is view all PCs on the network (both address ranges), but I can only see one IP address range at a time and only when I disconnect either the Ethernet or the Wifi connection.

I took a guess at bridging the two connections, but this didn't help.

Can Leo help or someone out there? Thanks in advance.

Hi I have essentially the same problem as one of the comments here (trying to have one computer connected to two different networks). The first network is an existing corporate network for stock and point of sale terminals etc, this is not under my control. The second is a small network, which is under my control, and uses a Netgear DG834GT wireless broadband router to connect a handfull of machines to the internet each other and a local printer. The two networks are currently completely independant of each other. However I now need to connect one of the corporate machines to broadband, such that it can send some stock data over the internet. So I have installed a second network card on this machine and connected it to teh netgear router. The result is that I have to disable one network to use the other). Now I understand this is due to IP conflicts, but what is the best way to resolve this? Should i use a different subnet to teh corporate network or something, and if so does this mean just changing the x in 192.168.x.1, for all computers on my netgear roueters network? Many thanks for any help.

Your LAN Card goes into some sort of router, right?
And Your Wireless Card gets your internet?

I had the exact same problem
What I ended up doing was going into the router configuration page and turning OFF the Deafault Gateway, DNS, and WINS, because my router had no iternet in it (it was just for the lan), and I was accessing the net through my wireless card. Once the router didnt tell my computer that it was the default gateway, I kept my net access through my wireless!!

Hope this helps :D

I have a wireless router at work which I am able to connect to no problems. I am trying to get one machine on but I am having great problems. This one machine is cconnected via ethernet to two till systems (through a wired router). I have managed to install a USB wireless network dongle and XP can see the network. Annoyingly, I can't connect.

I can't PING the router through command prompt - must be because it is the ethernet port which it is pinging.

Is there any way that I can have both the Wireless and Ethernet connections working but using the wireless as my internet connection without affecting the ethernet connection?

Hopefully you'll be able to help!

Hey there. I have a computer with two modems installed, an internal 56k and an external 33.6k. I can use a dial up connection on either modem to connect to the internet without any problems. However, I was wondering if it were possible to connect using both modems at the same time to theoretically double the downloading speed. I'm not talking about multilink per se because my ISP won't support that. I do have multiple dial up connections, from the same as well as different ISPs. Is there any way to get Windows XP to use both modems to connect to the internet (using different connections from the same or different ISPs) and allow me greater speed?

Hi i have somewhat of a complex problem.

I have a wireless network setup downstairs, and i have a computer and VOIP Router (Sipura 2100) upstairs. I can connect to the wireless router through my computer, but i want to be able to share my laptops internet connection with the VIOP box, but it seems that everytime i do try and use my VOIP i loose my computers internet connection. I'm tried to bridge, as well as just use the share internet feature but it doesn't seem to provide a stable connection i can actually use.

Any help in this will be Greatly! appreciated.

Thank you,

Hello Leo

i am really new to wireless nwtworks

fine i will explain my problem

i have a desktop & a laptop

My Internet Connection is of type : Cable Connection, aka from a cable modem

i have a netgear wireless router,ive configured the internet connection in a manner that i can share my internet connection & now i can acess the internet simultaneously from both the laptop & desktop and my desktop is having a wired connection to the router

router uses DHCP & assigned for desktop & for my notebook , i am able to ping to my router , but i am unable to ping to my desktop from my laptop , my main intention is to share files among them , please help me in this issue

Hi Leo

At work I have 2 different networks.

One of them is the corporate network, which is wired. It is used to have access to local computers and the intranet.

The other one is wireless and through it I should have access to Internet.

Currently I can get connected to both networks at the same time, but when I'm connected to the wired network none of my browsers or programs can solve the wireless network, so I can't really use it. The callings seem to go out through the wire network card and not through the wireless.

Is there something I can do in order to define that internet navigation has to go through wireless network and the other navigation through the wired network?

Thank you.

I have got a laptop & desktop. I have got wireless internet connection on my laptop. What i want to do is to share that connection, so i can access internet on my desktop as well. If i connect both machines via ehternet cable, the wireless connection just hangs. So, how can i connect two computers via ethernet and share wireless connection of one with the other.

I have two computers with different ISPs broadband with 64Kbps each. However, I was wondering if it were possible to connect using both ISPs at the same time to theoretically increasing the downloading speed.

You'll have to temporarily disconnect from router A, reboot while connected to router B, and then you should be able to access it.

I want to use both the wired and wireless connection at the same time but whenever i go on the internet, the browser defaults to the slower, wired network. if i disable the wired network, access to the net is fast, but i can not share files etc. So, is it possible to use the wired connenction for my files and the wireless connection for the internet at the same time? if so, how do i do it?

Hi Leo,
My situation doesn't seem to be answered by the thread so:
We have a peer to peer network in our workplace connected to one ISP.

I also have one computer set up as an ftp server with a different ISP and not connected to the LAN.

We did that because the FTP server ISP provides us with faster D/U speeds. We regularly upload or download 250-500mb files and it was slowing down our network as well as just taking too long.

How can I access the LAN without disrupting ftp functionality? Is it just a matter of installing another network card and connecting it through a hub to the LAN?

my boss wants the computers to be wired within the office. is this possible?

April 11, 2007 2:10 PM

Hi Leo,

I was wondering if i would be able to connect a to a wired LAN network (to another computer running Win. 2000 Pro) and still be able to be connected to my main Wireless Network (connected to a router in which i recieve internet).

The purpose of this is becuase i wish to use my wired LAN so that i can use the Win. 2000 computer as a second monitor through the program "Synergy," but i dont want to lose my wireless network, b/c then i dont have internet.

The reason im setting a wired LAN is because connecting that Win. 2000 computer to my wireless network would be arduous, since i would have to rename all the computers in my house to under 8 characters with no spaces.

I need assistance please.

I have a linksys wrt54g router with both computers running linksys wireless Pci linksys wmp54g. The problem is that I don't have broadband!, But I don't want to use it anyway, I just want to use the router to create the network and just use the network to share files and printers. Can this be done? If it can, can you give me detailed instructions to install to finish? Thank any advice would be appreciated!

I have a small office with 3 workstations connected together wired, we have a DSL connection and router.
We will be implementing a computer lab (6 PCs) in the 2nd floor, we are planning to swith our ISP using cable instead of DSL.

My question is, how can I use the same ISP-Cable/DSL to connect both locations (office and Computer lab), but in separate networks.
I want to avoid that the labs computers are able to see the office network.

What could be the best solution for security purpose and bandwidth


September 23, 2007 9:15 PM

Hey Leo,

Here's one for you. I have a PC with a USB wireless adapter which I connect to a network with. I also have a wired nic attached to a router, which is connected to my game console (xbox). The problem is when the wired nic is plugged into the router, i love my wireless connection. I have DHCP on the wireless, and a static IP with a different gateway on the wired router. So, is there something I can do to tell my computer to only try to send specific data (internet) through the wireless, and other data through the router?

September 23, 2007 9:22 PM

I LOSE my wireless connection.... NOT LOVE

September 24, 2007 9:18 AM

If you look into your tcp/ip configuration there is a field called METRIC.

This determines which network interface to send all traffic relevant to that network or any unknown network (aka web browsing) through.

This is what you need to configure if you VPN to another network that has the same subnet as yours, you lower the metric of the virtual interface so that all traffic to the "vpn" uses that interface.

What you need to do is enable load balancing on the interfaces that will alternate the load, intel and bcom both have software that enables this.
Unfortunately there is little to no support on doing so between a wireless and a wired interface.

Hi Leo,
I have a weird situation brought on by the internet provider at the dorm I live/work at. The ISP's DHCP server is randomly assigning people IPs on two different subnet masks, basically two different networks (.1~.63 and .64~.127, subnet mask We need file and printer sharing available to everyone regardless of subnet mask from our server. I have tried assigning the server an IP on both subnets (.6 and .119) with their relative DNS/Gateway (.1 or .65). The problem is that people on the .1~.63 range can access the .6 IP perfectly, but the people on the .64~.127 side can't access the .119 IP, even though it pops up on a netscan. The default "adapter" on the routing table is the .6 IP.

What should I do? Should I use 2 different network cards? I might try that in the meantime.

Thanks Leo.

August 16, 2010 1:09 PM

Not sure if someone said this already but Windows can only make use of one default gateway. To connect to 2 networks remove the gateway from the second one (I would pick the one you won't need Internet with) and remove the gateway. This means it needs a static address. Next set up a static route to the second network. This way your computer will connect to shared folders and Internet using (as an example) network and will know that anything on needs to use the second network card. You can also add entries to your hosts file for specific computers that you need to connect to often on the second interface.

My friend and i live 3 houses away from each other. We both have internet and would like to be able to network our two home networks together.

The issue is that we dont want to go through the internet to connect as we would like to share files without using up our ISP bandwidth limits.

I have a router in my shed that we can both connect to from inside our houses (i could even run an ethernet cable out there if needed but my friend cant). We would like to maintain our own seperate internet connections for standard use. But we want to network our networks together via the shed router.

Is this possible and how would we do it? We assume a lot of static ip addresses and renaming one default gateway ip address so that i dont inadvertantly start using his internet or vice-versa.

Thank you

I have 2 network , one is internal LAN & other is Internet. We have created workgroup in internal Lan using netgear router.

My PC has 2 Ethernet Card by which both network works

January 4, 2012 9:26 AM

wow lots going on in this article.
@thomask - yes you can. if your ip addresses are configured properly you should be able to see recources on both networks. ensure that ip addresses do not overlap int he two networks and you should be fine. e.g cannot be reached through your 10.x.x.x connection.

@Aran the newer windows xp and onwards do not have htis problem i have had upto 4 connections with DHCP enabled working and resources being access thru all four at times. However the setup for this kind of network is hard. static is not the only route. Ensuring there are no address collisions and a proper DNS setup on the networks can bypass a lot of these issues.

@Anonymous - Static might be your only route with reservation on all networks you need to connect to. also you could aggregate this into a VLAN through a switch and access it that way but that might require expensive switch and time to properly set it up and manage it.

@Qillz - assuming you have windows 7 and the shed router can broadcast a wireless signal, you could possibly set it up this way. Internet -> your computer's first NIC. second NIC to router in the shed. and enable file sharing services for the shed connection. Assuming your friends house can see the wireless signal he can setup a router with DDwrt or other solutions and rebroadcast your signal to his house.

@ Manpreet ensure your gateway ips are unique and not in the same range. e.g if your ip is with a subnet of then you should not have any addresses ont he other network within the range of - if you do then your windows will reroute your traffic looking for your gateways ip on the other network and when the gateway is not found or when the ip supposed to be the gateway cannot connect to the internet your internet connection will show to be down. Also this problem is also related with your OS as the new OS can auto detect which connection has Internet and reroute Internet request to there. E.g windows 7 when connected to any network will determine if Internet in available an route traffic accordingly. you are likely using xp.

For any of these solutions please feel free to post asking for more details here i will try to check when I can for updates or if i forget i am sure Leo can provide further help.
