I have tried plenty of wifi networks with my windows 7 laptop, and it works fine, except when I try to connect to my lumia 920 shared internet. Then is is BSOD. I tried upgrading the wifi driver but it still does it. Before upgrading it it would crash immediately after entering the password (wihtout the lumia saying "1 guest"). After upgrading it first connects ok (1 guest is shown) but it doesnt provide internet access, and if I run teh troubleshooter it crashes to BSOD.
What is hte difference between lumia 920 wifi and all others, that could possibly make a network driver crash? Even my old 800 wifi works fine, HTC sensation works fine, samsung Note is fine. It is only the Lumia 920.
I have exactly the same problem with my Lumia 920 and a Samsung notebook using Intel drivers. Rolling back to an older Intel driver (june 2012) avoids the problem.
I can run any other WLAN networks EXCEPT the Lumia 920 share, so I guess there is a driver error for both Nokia and Intel.
