Thanks for testing this, especially on real hardware and on both kernel versions. I originally ran into this while writing my own 802.11 stack and had only tested the fix with mac80211_hwsim, so it's good to see the same issue reproduced and fixed on actual hardware as well. > Still open is that an active monitor gets no channel at all when it is > created ... The initial-channel case is interesting too. That sounds like a separate issue, so I’ll keep this patch focused on channel changes. Matheus
