Problem with WIFI device
 

My window can't install it and show 'device can't be started ,code 10' or something like that.
It's really weird that 3 day previously i still used it and it's automatically disconnected and removed from my pc.
Somebody help me. :(

Does this WIFI device work on other computers? Do other WIFI devices work on your computer?

Yes it works on my friends but not mine.
Is it because of the virus?

You never mentioned any viruses in your post! But since it worked in other boxes, it's not the WIFI device, it's your computer.

I didn't sure about virus, my pc went crazy lately but my scanner can't detected it.
It's turn to be that my device has broken (first it temporary but now .....gone forever) I'm going to claim it. ;)
Thank you for your advice.
