I am running Ubuntu 18.04 on a AMD Ryzen system. I bought a PCIe Wifi Card, with the chipset "Qualcomm Atheros AT938x" (as I saw from windows device manager). The wifi card works flawlessly on windows, but on Ubuntu, I get these bunch of errors. I have already tried update and upgrade repo list and add to modules list.

I have updated the BIOS to the latest version, and I even updated my kernel to the latest point update.

I even added a line in the conf file if it helps, but it does not. cat /etc/modprobe.d/ath10k_core.conf
options ath10k_core skip_otp=y
[main] plugins=ifupdown,keyfile [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no
# /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. ath9k ath5k ath9k_pci
How do I make the wifi device work?
