I just wiped my dell xps m1210 because i am selling it, i reinstalled the operating system and used the dell resource cd to reinstall the drivers but I can't get my wireless to work

This model laptop has
DVD+/-RW with Dual Layer DVD+R write capacity

I think it is a probable driver issue and as XP is very limited on drivers being an obsolete OS I would go to dell.com and see if any drivers will fit your use.

I'm thinking you might be having a hard drive problem or the file structure is really messed up.
You had Win 7 and tried to install Win XP. Now it is confused, no doubt.
Here's the first thing I would do:
Put in your Win XP disk and boot from it.
At the first question it asks (about repair or install) choose repair.
It will then ask you which Windows Installation--choose #1 if it's there.
Hit enter if it asks for your password.
Now at the command prompt, type chkdsk /?
Depending on your version of XP, it will show you the switches you can use. Use the one that checks the entire drive. Might be chkdsk /P or maybe /F
Anyway, use the one that does the whole drive and let it run. Then try your reinstall unless you have file problems that aren't fixed.
BTW--your Dell should have a utilities option if you hit F12 at startup that will allow you to check your hard drive.

If you load a system restore point (Windows System Restore) the system will have the software settings returned to the way they were on the date the restore point was created. Any software install after that point will need to be reinstalled.

If you run a PC-Restore this RE-IMAGES the system to the way it was when it arrived from the factory. EXACTLY like it was the 1st time it was turned on. All Data files and software installed on the system will be overwritten.

Reinstall windows is one to the wipe out process.
Once you have reinstall the windows all date stored is your laptop is lost. You need to delete the drive D during installing process. Wipe out is not totally cleaned your laptop reinstalling windows provide a new copy of operating.

Try reinstalling the driver for the WEBcam/mic

The best way is with the Operating system disc and do a fresh install, thus wiping all installed programs and data files.

TRY TO REINSTALL THE DEVICE DRIVER FROM THE DRIVERS CD PROVIDED BY THE DELL TO YOU.
YOU CAN TRY TO TURN ON YOUR WIRELESS SWITCH WITH THE HELP OF DELL QUICKSET.

Beside reinstalling the camera drivers, also reinstall Direct X, if you don't have it go to:
