Possibly solved issues. As you say 
, go back to Microsoft's own WiFi driver version 14.8.8.75 per your instructions. Then reboot.
Then open the wireless driver advanced tag and: Update Driver> Browse My Computer> Let Me Pick From List Of Device Drivers On My Computer> select the Intel WiFi driver and hit OK. This reinstalls NETwNe64. Then reboot. The event errors go away. So the final config is:
- 14.8.8.75 Microsoft WiFi driver with 'N' enabled
- Update the driver to fix the corrupt NETwNe64 file
Only been running for an hour or so, but I'm not seeing the drop-offs or errors yet.
I suspect Intel's newer drivers break the NETwNe64 file in some way and this is what causes the 'N' instability...that's just a guess.
Two points:
- Intel, get a working driver for your customers. We've bought the kit... you need to keep your end of the bargain
- Intel, fix your program software. Windows 8 can not uninstall it and there's no manual process to do it either. This is a basic requirement of all windows software. I'm surprised it passed a windows compatibility test.
