I have 2 computers and an X-box hooked up to a linksys router. My firmware is updated and I use cable. One computer and an x-box have internet connection. But the 2nd computer doesn't have connection, it says it is connected, the task manager and my zonealarm firewall both show activity but it still won't connect to the internet.
I am thinking that my router is rejecting connection, I was thinking that since comcast recently took over the cable here that maybe they only allow 2 connections, but the x-box is plugged in the 3rd spot and isn't on.
The internet was working for that computer until I installed a new windows update this morning.
