What distro are you using?

Do you have the correct Driver installed?

you can simply do a lspci -l

Are you using ndiswrapper? do you have it linked correctly to the kernel?

wpa_supplicant enabled?

this is a good place to start...otherwise google linux and wireless...

If I understand you correctly, it does eventually connect, but it takes about 75 seconds, and then it will die out? or do you maintain connection?

I believe the issue is that specific card has had issues with compatibility. I googled and found this to be helpful.

I read this, and it sounded similar to your issue.

and about wpa_supplicant...

it would be in the sessions, down towards the bottom of list, if it is installed...

the wifi lost the connection already. It solved only reboot.

go to services ....

find wpa_supplicant, check and hit enable....

if it enables...then you have wireless, otherwise it will give you an should post that error so that we can see what the problem is.
