Got X3i Wireless to work but now my Latitude doesn't work!

My work machine is a Dell Latitude D600. The wireless connection worked right out of the box w/ this machine.

UNTIL...

I bought an X3i. I then made some tweaks to get the X3i working and now my Latitude doesn't work.

The Latitude sees my signal just fine, in fact it's around 100% almost all of the time, but I keep getting the message "one or more networks is available, click here." When I click there, I either see other SSID's or when I see mine and click go- it just goes back to the "one or more networks......" message.

Very frustrating.

Anyone else seen this type of thing?

btw. I have a Toshiba 3110ct that has worked fine over the wireless connection throughout this fiasco!
