Linksys WMP54G won't stay connected to the internet - Prompting a restart?

I cannot figure out why the heck this adapter keeps disconnecting from the internet for no apparent reason. I finally get the damn thing installed properly (Windows kept messing with the driver for some unknown reason) but there are still some unresolved issues.

-Sometimes the connection will be fine
-Sometimes the connection won't be fine-the PC will NOT ask me for the password/code (the router is password protected) and tell me that it could not connect.
-Sometimes the network doesn't show up. Restarting does not always help.
-Of course, there's also those unexpected dropouts. The internet just disconnects for no reason, and normally #2 is what results when I try to reconnect.

I have tried searching for better drivers, but f***ing Linksys doesn't have anything past Vista.
