Have been running 64-bit 7 for months with no issues using WPA2-AES with PSKs.

Many of our windows 7 clients have this problem. We found a solution: in the 
“Network Properties”, go to the “Security” tab, there is a button named 
“Advanced settings”.  Play with the check box of “Specify authentication mode”: 
some clients should check it, and others should uncheck it.

Good luck!

Subject: [WIRELESS-LAN] Windows 7 64-bit WPA2 Connectivity Issues

Anyone experiencing any issues with Windows 7 64 bit machines staying connected 
to WPA2-AES enabled WLAN.  Specifically the client associates and authenticates 
properly, is assigned an IP.  Shortly afterwords client is repeatedly prompted 
to enter their credentials. Disabling the client wlan interface seems to 
mitigate this for some time, but symptoms return, and interrupt client while 
connected to wireless network.

Running Cisco Lite weight ap’s on WISM’s, and stand alone controllers etc.  
Running 7.0.98.0 code.  Not seeing issues with XP or Vista machines.  Only 
common denominator so far has been 64 bit Windows 7 OS.  Doesn’t seem to matter 
if it’s Enterprise or Home version.

Thanks in advanced.
