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

Hi, I want to connect my desktop and laptop to a LinkSys hub so that I can access my high speed DSL internet on either computer, often simultaneously. However, my laptop says that there is an IP address conflict and subsequently disables the connection. How can I fix this problem -- I can't get another ISP, so I have to share this IP address.

To start with, if you're truly using a HUB and not a Router then that's 90% of the problem right there. A router of some sort is required to share a single internet address among multiple computers. It's fairly easy, and they're not terribly expensive.

The other 10% sounds like it might be configuration issue. I would double check the TCP/IP configuration to ensure that it is set to "automatically receive an IP address".

the answer is to ask your internet service provider to give separate ip addresses to each computer.then you can connect both onto the internet at the same time.after you connect it will show a seperate connection other then local area connection.that is your internet.the problem is your isp gives both computers the same ip address so two computers cant access the same ip address at the same time.if you do this you can connect two computers onto the internet at the same time using a modem with two ports.if you want this in English email me at {removed}@gmail.com and ill show you with pictures.

I had reliance dsl internet connection, and i install a router to it for use net connection in two system,but net is coming alternate, if net is coming in 1st pc so its not coming secong pc, if it coming in 2nd pc its not coming 1st pc.

Offhand I'd say that the router isn't properly connected or configured.

are the routers that comcast retns to you as good a quality as one you might purchase? I want to keep my desktop running as well as using a laptop and I pay for the modem anyway. They will offer me a free router since I have the modem renting from them anyway. Is the one they offer as good a quality as it shuld be or would you recommend buying your own? LIke I said, I rent the modem so there is no extra charge for the router? My friend has a router from comcast and says it doesnt always have a connection and my daughter had one from Direcct TV and she always had a connection problem. Why would this be? Thank you very much for your help.
