Missing WiFi interface?

[sportycliff]

Hi, and thanks in advance from a new member.

MacPro Duel Core Intel Xeon 2.66
running 10.5.8
3 gb ram

I've recently "lost" my wifi configuration from my network preferences. I may or may not have somehow deleted it, but it no longer shows up in the interface for services.

I was running a usb wireless lan card as I don't have an airport card. It worked fine till I "lost" it.

Any ideas on how to get it back?
Should I reinstall Leopard?
I'm currently burning a Lion Install disk (just put it on my MacBook), should I just wait and install that?

TIA,
Cliff

First, I would make sure the LAN card didn't die. Do you have access to another that you can substitute? And, it's probably not a good idea to install Lion until you get everything else worked out. Also, you want to make sure all your hardware is supported in Lion. Might be a good idea to have an Airport card on hand just in case.

Not the card, tried two diff, and they both work on other machines.

Do all your other USB devices work and did you try another USB port.

Yes to both.

Did you make a change or add an app in other words trying to retrace your steps to what may have coincided with the loss of wireless.
