Changing encryption keys

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?

Open up Network Connection and select the Properties page for the
wireless connection.

Select the Wireless Networks tab.

Select your network in the Preferred Networks list

Click the Properties button.

Change the type of protection and key value as required

Find the list of known SSID's to connect to and either modify or
delete the one you just added. The list can be found with:
Control Panel -> Network -> Wireless
Right click on Wireless (and I forgot where you go from there).
If you decide to modify, there's a page where it asks for the type of
encryption and the encryption key. Then "scan for networks" or
something like that, and your SSID should reappear. (Sorry to be so
vague but I don't have an XP box in front of me a the moment).

For WEP, I suggest you use the Hex key, and not the ASCII key. There
are two different algorithms for converting ASCII to Hex and Windoze
XP only supports one of them. Hex always works, but ASCII can
sometimes screwup.

Thanks to both of you for your quick replies. Works perfectly.
I knew there had to be a configuration option somewhere; I just
got lost looking for it.

Sometimes screws up, I've never seen it work, you must have the luck of the
Irish if it has ever worked for you.

fundamentalism, fundamentally wrong.
