I recently had my R7 replaced due to a wifi issue which is now fixed.
I had ordered an Intel 7260 wifi card to replace the card in the old laptop, but decided to send it back instead.
I am ordering more ram, and I still have this 7260 card. Because it is a better wifi chipset (compatable with the new wireless AC spec), I am thinking about upgrading the wifi chip while I have the laptop open.
HOWEVER, I recall seeing some reports on here that people who installed that card never got the bluetooth working. (it IS a combination wifi AND bluetooth card).
I do know that those reports were prior to the windows 8.1 update... so I dont know if anyone ever found a working driver, or the situation is improved in 8.1.
Can anyone comment on this? Have you upgraded to the intel 7260 and do you have bluetooth working?
