When I connect the wi - fi, 1 only one computer can access it, and my computer does not work.

I have to plug the ethernet cable directly into the ATT modem for computer work, so when I hook back in ethernet cable to a Linksys wireless modem, computer at home does not connect & only 1 laptop in the House connects to the time? When I'm addicted to the Wi Fi & will not work my computer at home, I click on the tab "run diagnostics" and he teaches me something about my IP address, but it is impossible to remedy. And my son can't use his laptop or his XBOX live when my daughter is on her cell phone and vice versa.

Very frusterating! It worked just fine and then one day suddenly it happened. I called Att which is my DSL connection and there is nothing wrong with their modem or with the connection to att. I even bought a new linksys modem that has the wireless and the modem router all-in-1 and had the same problem. Help! I can't ask Dell toll-free because my warranty has expired.

It's as if the computers are in competition with each other for internet access!

Hey Sandra0lynn,

I moved your thread to the Internet Explorer for Windows Vista - networking forum forum and marketing online.

It seems that either DHCP has been disabled on your router and/or all your computers are set to use the same IP address.

First log into your router and verify that DHCP is turned on or enabled. If you need to know how to connect to your router and check this option, you will see the user manual or online help supplied by the manufacturer of your router because steps varies from a manufacturer (as well as models).

After that make sure you that DHCP is enabled, the next step will be to IPv4 each computer and IPv6 resolves to get automatically. To do this, take a look at the procedure in the below link and select obtain an IP address automatically for both types of connection.
Change TCP/IP settings

Hope that helps.
