WiFi not working on kernel 5.11

After Manjaro upgraded to kernel 5.11.1 wifi refused to work. Although after selecting kernel 5.10.19 everything is working smoothly. Decided to wait until the next kernel update. But with kernel 5.11.2 the problem is still there - WiFi doesn’t work :(( I’m using laptop ASUS K50ij
inxi -N output is the following:

Device-1: Qualcomm Atheros AR9285 Wireless Network Adapter driver: ath9k 
Device-2: Qualcomm Atheros AR8121/AR8113/AR8114 Gigabit or Fast Ethernet 
driver: ATL1E 

Did anyone encounter the same issues? Is Qualcomm Atheros AR9285 no longer supported in new kernel releases or I need to tweak any settings?

Does sudo dmesg | grep -i ath show anything on the 5.11 kernel?

Yes, the output of command is below:
