sorry for late answer
I did not enable scaling.
Still having the issue and I moved to asus RT-AX53U
So far, so good, after removing the
schedutil CPU governor from local startup!
2.4Ghz radio has been running fine.
Do you recommend
ondemand? Apart from the trivial increase in CPU temp from running in
performance, any other downsides?
That was just an explanation my cpufreq settings manipulation example in that same message.
I have been happily using ondemand in my dumb AP RT3200 (that does not use SQM).
But I have noticed (or at least suspected) that cake qdisc in SQM may suffer from changing CPU frequencies, and do prefer the old simple.qos with fq_codel instead of cake.
