Atheros 802.11 wifi chip can support superchannel.I can success use 2576mhz in monitor mode. I have success inject and catch packets from mikrotik which support superchannel too. But when use hostapd in ap mode. ath9k debug report: ath: phy0: Enabled BB Watchdog timeout (85 ms) ath: phy0: missed 1 consecutive beacons ath: phy0: missed 2 consecutive beacons ath: phy0: missed 3 consecutive beacons ath: phy0: missed 4 consecutive beacons ath: phy0: missed 5 consecutive beacons ath: phy0: missed 7 consecutive beacons ath: phy0: missed 8 consecutive beacons ath: phy0: beacon is officially stuck The log comes from function: void ath9k_beacon_tasklet(unsigned long data) and then will call ath_reset. I think freq is right in ar9003_hw_set_channel although i can not find register description in the datasheet. My chip is ar9330 macRev 1. In atheros datasheet, i cannot find wlan related register. ar9330 is AR9003 hardware familiy chip in ar9003_hw.c.
