Hello, I testedversions16.11.0, 15.9.0.5, 14.2.0.10 and 14.0.1.2.
Only the14.0.1.2version works fine withallwirelessroutersI testedwith myLENOVOT420equipped with thewireless cardIntel CentrinoUltimateN6300AGN
The fix for me consisted of a few things:
1. uninstall intel pro/set software
2. in device manager uninstallall versionsofdrivers Centrino Ultimate N6300 AGN and check the optional box for removing the drivers as well. (do it as many times as necessary)
3. extract the intel 14.0.1.2 drivers (only drivers)
4. Launch device manager again
4. in device manager right click your computer at the top of window and select scan for hardware changes and the 'network controller' with a yellow warning icon should appear. Right click 'network controller' and select update driver.
5. in driver window select browse my pc for files and navigate to the location where you un-zipped the 14.0.1.2 drivers files/folder.
6. Install drivers
