Are you also seeing the same behavior in your setup? Could > you please share your results? Sorry, I've been travelling this week; I'll be back in the office next week and can run some tests then. I may also have an idea for a different algorithm that will work better in pull mode, but need to see if it works at all first :) How do I force ath10k into push mode? -Toke
