Can't connect to wifi standard n (below ac)

I have windows as the second OS, I can connect to my wifi that uses n standard.
But I can’t do it using Linux.
Infinity “Configuring interface”.
Also, I have second wifi that uses ac standard, and Linux can connect to it.
I think because I have wifi-adapter “Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter” for 802.11ac standard. But how it works on windows? Maybe I should install some drivers on linux?
Thanks in advance!

Hello @opt :wink:

Please add these output of the terminal:

inxi -Nazy

Drivers for that adapter are already included in the kernel. It’s the ath10k module.

Searching these forums, our archived forum and the Arch forums should yield good results.

Device-1: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter

Maybe dmesg shows more information:

sudo dmesg | grep ath10k

Also a full journal log could help to see a hint of your problem:

journalctl -b1 --no-pager

And sure in the forum are a lot of problems with that driver.

sudo dmesg | grep ath10k:
