It's probably worth reading the last 2 to 3 pages as they sum up most of what's available to do in your situation. The main options seem to be (in order):
- Disable N and/or change a few setting for the card - this works against some access points but not all.
- Disable WiFi and buy a USB WiFi transceiver - worked well for me as a temp fix on some Access Points that Point 1 did not fix. This is not great but works.
- Rollback your drivers to the original windows drivers - you get WiFi and Bluetooth, but lose WiDi
- Open the machine and replace the card with another maker's.
Over a few weeks I've done all. The best has been to replace the card and hold on to the Intel lamer should a driver be released by Intel. I'm not holding my breath given how long this issue has been running, but better than nothing. On a reply of mine earlier on I point to my Blog post which has a table of cards (thanks to another poster here) and description of opening up the machine (Samsung T700 in my case), replacing the card, and getting it going.
Good luck.
