Low connection speed (ac, 5ghz, LAN) #22

Hey. I've been using a rtl8821cu driver from another repo and getting decent speeds of ~200Mib.

That driver does not yet work on the latest kernels, so I've tried yours (installed from the AUR) which did install, but I'm only getting speeds of about 20-30MiB-- even across the local network.

I checked iwconfig and it's running it on 802.11ac, 5.22Ghz, so I'm stumped as to why the speed is so bad, any ideas? It's a Tenda U9 dual band adapter, on linux kernel 5.3.6-arch1-1-ARCH.
