Linksys "internet cannot be found"

I run a Win98SE, with a WMP54G linksys wireless card. In rearranging my room, my card got knocked out. Not knowing this, I uninstalled everything and reinstalled it. Took the card out, installed the software, put the card back in, rebooted a million times, etc. Now I can connect to the network, but it says the internet cannot be found anymore. The network has WEP 128-bit encryption. Any suggestions on what I did wrong this time around would be most appreciated.
