o wifi connections available in Manjaro Linux

[Xell Kim]

Hi! Sorry to interrupt you. I'm a manjaro user and met some problems
about the wireless configuration.
My new pc has Qualcomm Atheros QCNFA765 as net card and the default
driver for it in manjaro is ath11k. However, wifi service seems to be
unavailable and there's even no wirelessLAN interface in the rfkill
list. Besides, I should mention that the wireless service could work
with no problem under Windows system.

I've noticed an error info " mhi mhi0: Direct firmware load for
ath11k/WCN6855/hw2.0/amss.bin failed with error -2" but have no ideas
how to solve it.
I also tried modprobe ath9k but it didn't work. When I try to modprobe
-r ath11k_pci, my terminal got frozen for minutes and I had to stop
it.

I would really appreciate it if you can help!
