Dell Latitude E6400 Laptop Wireless not working

XP Pro.
Works fine with eithernet cable. I had malware, and cleaned it all up with the wonderful help here, but I noticed wireless isn't working. I haven't a clue how to figure out what is wrong. Here's my thread: http://forums.majorgeeks.com/showthread.php?t=259088

It doesn't bring up a Dell application in the start-up column. I look over drivers, they all seem to be there. When I move the wireless switch, the light comes on. Seems as if it should be working. I fear I've removed something from it.

I can get more information, if anyone has some ideas. Thankyou so much...:wave

 

If wireless shows up as a device in the adapters, right click and make sure it is enabled.

 

Thankyou...it just wouldn't run at all, but I googled on how to use the Windows setup in Services, and that worked and the wireless now is working...thankyou for replying and I learned a lot more about how this worked....
