Dell Latitude E6510 Intel Centrino Advanced-N 6200 AGN intermittently disconnects from wifi

I ran across a problem with this model laptop not connecting to our corporate wireless network or it would connect but disconnect intermittently. The laptop would, however, connect to our guest network which had no security. In a nutshell, the wifi driver for this adapter needs to be updated. Microsoft Update and the online checks indicate that the laptop has the latest version which was v13xxx. By visiting the Intel site directly at http://www.intel.com/support/detect.htm an updated wifi driver is needed and can be installed (v15xxx). After this upgrade the wifi connection works as expected.
