Hello,

You either have a hardware failure or a software failure.

Look at the configuration screens on the access point, and see if the network is still defined based on how you set it up. See if someone hacked you by tapping into your network. See if the WEP security has changed.

Look at your adapter. Do you see any blinking lights like you used to?

I am assuming you are using Windoze. Is the device active and proper in the device manager? Are the protocols properly setup?

I personally do not like the Linksys equipment. They are RF noisy (meaning they transmit signals that should not) that interfere with my radio stuff. I have Buffalo Technologies access points, and a variety of adapter cards for my Mac and Linux laptops.
