WPA2-AUTO DHCP Problem with Windows 8

I recently faced a WLAN problem using Windows 8 devices. The WLAN was configured to use WPA with a pre-shared key. The network was working fine with Windows 7 devices. However, devices running Windows 8 only had limited connection with a auto configured IP address and did not use the DHCP configured IP range. The problem was solved by changing WPA2-AUTO to WPA2.

Upgrading Windows 8 Release Preview to RTM

Windows 8 Release Preview was quite ok and therefore I’ve run it as quasi production system on my HP 8540w. Although upgrading from any of the preview versions is not supported, you may convince the installer to perform an upgrade by modifying the cversion.ini file, see Bing. Here are some key applications I’ve run on Release Preview:

Dynamics AX 4.0 SP2
Dynamics AX 2009 SP1 RU8
Dynamics AX 2012 CU3

HyperV Role
PPTP VPN connections (3)
Office 2010
Drivers for HP 8540w

Visual Studio 2008 SP1
Visual Studio 2010 SP1
Visual Studio 2012 Preview

Virtual PC SP1 Network driver
Device Emulator for Mobile 5/6
Windows Mobile Device Center
Zune for Windows Phone 7

Almost everything was ported successfully. Unfortunately the Virtual PC network driver for device emulator was not working, and the VMs could no longer connect to the network. However, after uninstalling and re-installing Virtual PC 2007 x64 the virtual network adapter was working. Some SQL Server components also reported compatibility problems. Manually cleaning the system drive will remove the old installation and some GB hard disk space.


Update 28.8.2012
Windows refused to boot anymore and was stuck at the windows logo. However, after the fourth boot killing power-off windows recognized that it requires a repair. After 20 minutes black magic self healing its working again.
