Hello I also have the dodgy network card
1.2.4GHz
2. Win 8.1
3. At home across the board very regular and often just cuts off still shown as connected but nothing works, connected to a standard Virgin router nothing fancy about it. At work less frequent despite being connected to the server and working heavily over the network connected to a Draytek 2860n router.
4. Quite a few however at home I have switched to channel 13 were nobody operates for some reason so have it all to myself as well as having nothing in 10, 11, 12 or 14 and at work IT have spent quite some time optimizing the channels and so on
5. Across the board from what I can tell no specific action causes it to occur
6.Disabling uAPSD has helped in my opinion havn't done a scientific test but it feels less frequent since the change especially at work. Switching off bluetooth is no help plugging out mouse and keyboard 2.4G dongles does not help. I don't know what VHT is??
7. Lenovo Yoga 2 Pro
8. Yes, this unit is only 2 months old and has not been modified in any way
Would really like if there was a patch or update to fix this as I do not want to have to send it back and be without it for many weeks,
Appreciate your help
