I have a sony laptop that has been rebuilt and is connected to our domain. However, after rebooting and attempting to log in. I get the dreaded grayed out login and delayed login and I have pinpointed the issue to the wireless card. If I turn the hardware switch off I can login within seconds, when the switch is on the login in process can be upto 5 mins. Having the client turn the wireless card off during login and turning it back on is not an option.
The wireless card is a Intel® Centrino® Advanced-N 6200. There is only one wireless network profile in windows wireless, I have also removed this as well. I have ensured all updates windows, bios, and system updates have been applied and have even used two different wireless drivers one directly from the Intel and the other from Sony's website to no avail. I made sure to uninstall the Intel Proset wireless software and only installed the drivers.
I have hard coded the dns and ip and ensured dhcp is correct. I have flushed the dns. I've installed and reinstalled the wireless drivers so much that I am upto wireless local area connection 11. I am at a loss.
