If you just read the mvm->radio_stats.on_time_rf (in usec) then you see following:

So it also jumps all over the place. This could be investigated further but I
just wanted to mention it here.Sorry, wanted to write more about it last week but forgot about it. If I basically filter out the upper 32 bit in mvm->radio_stats.on_time_rf then it didn't look that bad on a AX210. It seems like the upper bits is sometimes 0x00000001 for unknown reasons. Like it would be some kind of flag which should indicate some kind of change/event. So maybe the firmware team could check what this means. It is not really urgent - I just got interested in the problem :) Thanks, Sven
