Sorry but yet again my unbelievably frustrating computer has broken!!!

My wireless is set up to two computers. My router is working okay and one of the computers is working okay. However, my other computer is connected but it says that there is limited or no connectivity. I do not understand this at all! When I decided to find out what was wrong, I had the option to repair the connection yet after trying it twice all I got from it was that it could not repair it because it was unable to renew the ip address. I can no longer click on the repair button and am in need of some help. So if anyone can give me a hand it would be greatly appreciated.

Is this computer wired to the router? I had this problem occasionally. To remedy, disconnect and reconnect the LAN cable at both ends. This sshouls fix it, most likely. If it is wireless, then you may have to reset the router. (Switch it off, then back on again)

Thanks, CT! This worked for the moment. My connection has been made from my wireless router to my computer's pci card but now the programs that use the internet will not use this connection. Internet Explorer comes up with the Cannot find server page and I'm pretty sure that it isn't even looking for a connection and is instead going straight to the cannot find server page. Can anyone help me?!?! Thanks!

Do you have a broadband modem? This sounds like what used to happen to me last year. We had a stable connection for months, then we unplugged it one time, after that the modem would crash periodically. You could tell it was the modem because you could still access the router. Try resetting both the modem and the router. Switch off the router first, reset the modem, let it load for about 30 secs, then switch the router on. This solved most of our problems.
