Reducing CPU load of Wifi driver (mt76x2u)
by kernash from LinuxQuestions.org on (#6HMJS)
I have these USB sticks on embedded PCs and the driver seems to be using about 20% CPU, even if there is very little data transfer. Unfortunately I'm in lack of CPU cycles ...
Before I had other USB sticks, which used basically no CPU at all, but they only supported 2.4 GHz.
Now I tried these sticks (Fritz!WLAN AC 860) which use the mt76x2u driver.
Is there any way I could lower the CPU usage?
There are five processes which use CPU:
1x "mt76-tx phy1" which uses the majority of the CPU and
4x "kworker/u2:[1234]-mt76"
