Hi guys, Connecting to 5GHz router with my iwlwifi (on Yoga 2 Pro, 3.13 kernel) seems to work fine, but 'dmesg' doesn't look pretty. This is what 'lspci' say about the actual controller: Intel Corporation Wireless 7260 (rev 6b). IIRC this was going on with 3.11.y and 3.12.y as well. Please let me know if i can help with anything else. cheers, Petko --- part_of_dmesg --- iwlwifi 0000:01:00.0 wlan0: disabling HT as WMM/QoS is not supported by the AP iwlwifi 0000:01:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the AP wlan0: associate with 00:25:9c:24:d5:4c (try 1/3) wlan0: RX AssocResp from 00:25:9c:24:d5:4c (capab=0x411 status=0 aid=1) wlan0: associated wlan0: deauthenticating from 00:25:9c:24:d5:4c by local choice (reason=3) cfg80211: Calling CRDA to update world regulatory domain cfg80211: World regulatory domain updated: cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S wlan0: authenticate with 00:25:9c:24:d5:4d wlan0: send auth to 00:25:9c:24:d5:4d (try 1/3) wlan0: authenticated wlan0: associate with 00:25:9c:24:d5:4d (try 1/3) wlan0: RX AssocResp from 00:25:9c:24:d5:4d (capab=0x11 status=0 aid=1) iwlwifi 0000:01:00.0: Microcode SW error detected.
