Windows 8.1 Latitude E6430 Wireless Issues

After a recent clean install of Windows 8.1 on my Latitude E6430, I can no longer access my work wireless network with utilizes 802.1x and Cisco wireless controllers.

This is using the RTM version of Windows 8.1. Windows 8 and the customer preview of 8.1 worked without any problems. 

Windows installed the Broadcom 802.11n Network Adapter upon installation. When that didn't work, I updated the driver using the Dell support site and installed the Dell Wireless 1504 802.11b/g/n (2.4GHz) drivers. 

Both drivers result in the same thing: I get connected with limited connectivity and usually a self-assigned IP. 

The wireless works fine on home networks using WPA2.

Any ideas or troubleshooting suggestions?
