managed to make it work again.
in some thread I read to uninstall Zone Alarm. And so I did. After reboot WiFi worked again.
So here is what you do
1. go to CMD, type ipconfig /all
if your wireless card is not listed, try uninstalling Zone Alaram, reboot, reinstall wireless drivers
Spent two days and four clean instalations of Win 7 x64 and could not get my WiFi internet to work, some 8 hours on the web searching for clueas and answers. Your post made my day. Did as you said and works now even after reinstalling ZoneAlarm. THANK YOU Martin_SZ.
I'm glad you fixed yours too.
I'm not sure to whom we should forward this problem - is it Intel's, Del'sl or Zone Alarm's defect?
Let's just hope that somebody from Intel is reading this and will forward it to whom it may concern.
