No AC enabled with A6210 card? (slow speeds)

[maluhia]

My speeds are orders of magnitude slower on linux than on windows. I get ~150mb/s down on windows and and ~5mb/s down on linux, respectfully. A6210 uses MT7612U chipset.

running 5.0.10-arch1-1-ARCH. Connecting to my 5GHz network.

@maluhia : mt76x2u dongle is just receiving, right? Moreover signal strength seems pretty low to me

[maluhia]

@LorenzoBianconi I can send and receive data with this dongle, as I did a speed test and got 11 Mbps down, 702 kbps up. Signal strength isnt the best, but I havent moved the dongle and get 10x the speed when I boot into windows and use their drivers, connecting to my wifi over ac band. I am curious if maybe ac isnt enabled for these drivers in linux, but I cannot tell

I ran another test right beside my router in Linux, and booted into windows and ran the same test (internet speed is 300/15):

Linux: 167Mbps down and 5Mbps up Windows: 165Mbps down and 15Mbps up

I wonder why the upload is slow in Linux? No other devices were on the network.
