Code 31 on Wireless-AC 7260 install


Installed a new Intel 7260.HMWG.R. Revised Wifi Wireless-AC 7260 H/T dual band 2x2 AC+Bluetooth in a Dell N4010 laptop running W7 SP1 - old Centrino Wireless-N 1000 completely stopped working. Prior to the swap, I uninstalled all other wireless and bluetooth adapters via device manager, then installed 7260 driver version via the ProSet Wireless package, and later again via the driver-only package.

Initially, could not get the wireless adapter to show up. Bluetooth adapter installed with no problem. Went to device manager and manually added via the "add legacy hardware" menu option. 7260 hardware showed up, but shows a code 31Have run the windows troubleshooter with no success.

What is the fix for this?

We also would like to take this opportunity and inform you that Intel does not support integration which is when a wireless adapter is replaced by another one.
