I'm running a WRT54GS router with WPA encryption and my laptop connects just fine using the built-in XP wireless software.
I lowered the encryption in the router to WEP so that an old Win98 laptop could connect with its 802.11b card. Now, when I try to connect with the XP laptop, the connection tries and fails because it's still trying to use its stored WPA key. How do I get the XP laptop back to the point where it asks me for an encryption key instead of just assuming that the previous key still applies?
