How come we cannot get both of our computers online at the same time?

by on November 10, 2009

Q: We have 2 computers in the house with one Internet modem and a Cisco wireless router. Only one computer can get online at a time though. When we turn the 2nd computer on, it will connect to the Internet, but it disconnects the first computer. Is there a way to get both computers online at the same time?

    When you say modem are you talking about a dialup modem, a dsl modem or a cable modem?

    It’s a cable modem

    Thanks, how do you have everything hooked together?

    For example: are both computers connected with Ethernet cables to the Cisco router, and then the router connected to the cable modem with an Ethernet cable?

    The Cisco router is connected to the cable modem by Ethernet cable. The computers both have wireless connections to the router. One is in the room with the modem/router, the other is in the bedroom right next door.

    If one of them is in the same room as the router, I suggest trying an Ethernet connection instead. If you need a cable you can grab one here for under $5 – http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10232

    I had a problem like this years ago and what was happening is both computers were getting the same IP address. You should make sure that computers are setup to use a DHCP address server (ie pull an IP address from the router) and make sure that they both have different IP addresses.
