To naveen,

Well I think you would have to get a main router with 3 or more WAN ports for the internet connections (one for each dsl line) then connect the computers to the LAN lines.

Hello:

Need a little help on what to get. I am hooking up two seperate networks that will feed both audio and video I need to then hook up each network so that both can be viewed from two seperate locations. Do I need to use a router or switch for each one or can I just use one to view both? There will be no Internet connection on either network but I am concerened about the integrity of each network. I was thinking a router for each due to only having one uplink I don't know of any other way to do it and keep them seperate. Thanks.

Jim

Mark: what you're doing sounds fine. The only time I'd be concerned is if you were planning on very heave data transfers between either of those two remote computers and one of the others. But what you've described is very close to what I have in my own home.

I was just wondering if a router can make a home network connection speed faster in anyway?

It can, but it's very rare. If there is are machines communicating with each other on your local network, and they're using LOTS of bandwidth, a router or a switch can isolate their traffic so that it doesn't impact other machines. But 99% of the time you'd never notice.

hi should i use a hub, router or switch to connect computers on a 3rd floor to computers on the 1st floor, i am also wanting to run a web server with a pemanent link to the internet

Thankyou
Freddy

Has very little to do with the floors - it depends more on the number of computers and how much traffic you expect, and what kind.

well i own a mobile phone shop and want to connect PC's together for account purposes (7 to 10 PC's

Sounds like simple setup very much like that outlined in the article. Use a router to take in your internet, and then if you need to add more ports, use a switch as well, and you should be fine.
