Can I use my psp as a wireless card for my Laptop?

Sorry, you can't. I think your wireless card doesn't work because you have to reinstall the driver, the card went bad, the laptop went bad, the router went bad, etc., etc. IOW, there's no way to tell from here. (The way to tell is to install the adapter in another computer. If it works, install another adapter in your computer. Etc. It's called "substitution".)

umm i u download the inclusive windows vista psp wireless card download thing off google it should work but the download is REALLY HARD TO FIND took me 3 hrs to find it if i had the link i would give it to you but i dont srry but goodluck finding it! =)
