I have a IFC6410 with a QCA6234 (AR6004) chipset for Wifi. I tried to use hostapd on 802.11n mode, but it doesn't work: Mode: IEEE 802.11g Channel: 9 Frequency: 2452 MHz DFS 0 channels required radar detection nl80211: Set freq 2452 (ht_enabled=1, vht_enabled=0, bandwidth=20 MHz, cf1=2452 MHz, cf2=0 MHz) nl80211: Failed to set channel (freq=2452): -22 (Invalid argument) Could not set channel for kernel driver It seems this is caused by a missing feature on the firmware, namely ATH6KL_FW_CAPABILITY_RSN_CAP_OVERRIDE, and indeed RSN cap override is not supported by the current firmware version: [ 7.524921] ath6kl: ar6004 hw 3.0 sdio fw 3.5.0.349-1 api 5 [ 7.524960] ath6kl: firmware supports: 64bit-rates,map-lp-endpoint,ratetable-mcs15,no-ip-checksum Removing this check on drivers/net/wireless/ath/ath6kl/cfg80211.c, as described on this message at linux-wireless http://www.spinics.net/lists/linux-wireless/msg115085.html will let the hardware go into 802.11n operation while on AP mode, but as reported by this user, WPA2 is broken (clients are unable to connect) apparently because of this missing feature, but it works on open and WPA. Unfortunately this workaround isn't acceptable, as my clients are all standards compliant and won't enable HT mode on a WPA network! Is this possible to be fixed as a update to the firmware files, or is it a hardware limitation of ar6004? _______________________________________________ ath6kl mailing list ath6kl@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/ath6kl
