Do you have idea what is this? It sounds like maybe the beacon gating of the TX queue is not functioning? It's possible that MAC changes between AR5212 and AR5416 are the problem? > "ar5416PerCalibrationN: NF calibration didn't finish; delaying CCA" =A0sh= owing > while the TDMA wlan0 interface is brought up Oh, that can be ignored. It just meant the initial NF calibration during interface setup didn't complete very quickly, so it's delaying the CCA load (as the values needed aren't yet available.) The initial NF calibration can sometimes take quite a bit longer than 10ms. Adrian
