Bluetooth problem on X399 Taichi

   ok, so i exchanged the intel 9560 wifi card for mediatek mt7922 in a Dell 7400 2in1 laptop.

in windows it does not work. You have to connect internet to download drivers. I tried.. dell drivers this time - the wifi card was not recognized. I gave up. Windows bare metal without internet will be even better.

it works out of the box in linux. the traansfer speeds are faster, the signal is better but what is most suprising - the battery life is better. I thought it was to be opposite, because 9560 is cnvio or something - its suppose to offload functions to cpu. Considering i bought this laptop refurbished with battery described as 'faulty' and now it can work 3.5h this is nice (used to be ~2.5)
