I had similar problems installing 7.2 onto a couple of Dell E6xxx
laptops with
Intel Corporation Centrino Ultimate-N 5300/6300 cards. It lets me
configure the network at install time but when I boot there is no wifi
device.
Partial solution.
Laptop 1. ( install when 7.1 was latest release )
installed 7.1 no wifi
installed 7.0 wifi works
upgraded to 7.1 several months ago wifi works
upgraded to 7.2 when it was released wifi works
Laptop 2 ( install when 7.2 was latest release )
installed 7.2 no wifi
installed 7.0 wifi works
upgraded to 7.2 ( last weekend ) no wifi
Any ideas.
Regards
Tony
