One of my connections stopped working all of a sudden. My other ones work so the wi-fi is still working. Other devices work on the wireless router and I've checked my WEP key several times. What could be going on?

Thanks!

The router for this connection may have recently been set up to restrict access to a list of devices. Your device may not be on that list.

The router hasn't been touched and I looked through the settings. There are no restrictions. What else could it be? I can see the name of the router under connections and the signal strength bar is maxed out.

*FIXED - Not sure why but I manually typed in the IP address and it magically did the trick. Not sure why it stopped working or why the auto-IP didn't pick it up but it works for now.....
