Unable to connect to a secure wireless network - Event ID: 8002 Task Category: AcmConnection..., Event ID: 11006, Event ID: 11006

Question

Hi, 
I have a Dell Latitude E6440 running Win 7
Enterprise 64 on a domain. It will connect to any unsecured network, and it can see the secured network in the list when I click the wireless connection icon on the system tray. When I go to manage wireless networks, the secured network does not show
up (and thus, I cannot delete the network to try to re-add it). Normally, we would add the secure network here. I click Add, give the name in the correct syntax, add the needed information (WPA/2-Enterprise, EAS or TKIP), and hit Next, it immediately returns
with "An unexpected error occurred". A similar thing happens when I hit Connect from the list of available networks that pops up when I open the system tray icon: it says it was unable to connect, when I hit troubleshoot, it says that it could not
identify the problem. The event log shows the error below. I haven't been able to find any resolutions here or elsewhere that address the fact that I can connect to unsecured wireless networks, but not secured wireless networks.
Other notable troubleshooting steps:
Uninstalled/Reinstalled wireless adapter with the latest driver
Other laptops are able to access the same secure wireless network
The first WLAN-AutoConfig error in the event log was Event ID: 12013, attempting a 802.1x authentication. Then Event ID: 11006; stating "Explicit Eap failure received". After a few days of alternating all 3 errors, they started to only error on
Event ID 8002.
