X96 Max Plus Q2: Wifi (qca6174) slow/lagging - caused by wifi power management

[votarum]

It appears that the issue caused by power management. I installed wireless-tools package:
apt install wireless-tools
and disabled wifi power management:
/usr/sbin/iwconfig wlan0 power off
After this lagging in ssh console stopped, and spontaneous disconnections from the access point as well gone.

Serious? That is really good to hear!

Thanks for the tip. And if it is true, I will disable CONFIG_CFG80211_DEFAULT_PS once and for all.... Maybe that wll solve it too and maybe it will solve numerous other wifi problems.

Thanks.

Yes, unfortunately this problem often occurs with various wifi drivers. If the device is not mobile, it is always better to disable power management.
