Do you have CONFIG_ATH10K_DFS_CERTIFIED enabled? Also check that that regulatory is correct with 'iw reg get' and 'iw phy0 info', especially that 80 MHz channels are supported. Also I would try first without DFS on channel 36 just to make it easier to pinpoint the problem. -- Kalle Valo _______________________________________________ ath10k mailing list [email protected] http://lists.infradead.org/mailman/listinfo/ath10k
