Dear all, I have been trying to set up a wireless network (tested both managed and ad-hoc mode) with HT40 enabled using Atheros chipsets and thus the ath9k driver. In both cases, iw responded with: Command failed: Invalid argument (-22) when e.g. executing the command: iw dev wlan0 ibss join network 5180 HT40+ Is this not implemented or is this a (known) bug? System: Linux OpenWrt 3.3.8 driver: ath9k Best regards, Erwin -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
