What didn't work?

First of all, Thanks for bringing this card into linux world. Speed is very low and it's really unusable with such high ping. In windows & elementary OS(Based on Ubuntu 16.04), I used to get 84 Mbps & 50 Mbps @3ms ping respectively but Arch Linux barely goes over 2 Mbps with very high ping.

What did you try?

[I also tried AUR package from the user repo who repackaged your script without any luck.]

Error code:
