I have been using my laptop to connect to the internet using my Nokia N9 hotspot successfully for a year or so. Yesterday I upgraded the laptop from windows 8 -> 8.1 and now can't see the N9 hotspot. I've tried rolling back the laptop WiFi driver but still the same. I can still see and have used 2 other WiFi connections, but not my N9 one. (using one now!!) Does anyone have any idea's or solutions to this?
