we have released a new firmware for 7260, 3160 and 7265 Intel WiFi devices. This firmware is supported starting 3.14 kernel (when [2] will hit it). We have a here quite a few bug fixes with a few new features advertised by flags in the firmware file. The most visible bug fix is a ping loss issue we had with certain APs when using uAPSD.
Excellent! I've actually been watching almost-daily for a new firmware version, hoping it'd help out some of the issues I've been having with a 7260 on a Cisco 802.11ac network. Primary issue is that my laptop would suddenly pick an AP with a very weak signal, and my connection would end up breaking to the point of being unusable until I reconnected (I think this is actually wpa_supplicant's job, not the card/driver/firmware, but since it worked fine on an old 6300 card on 802.11n I figure there has to be something with this card causing issues.) With a combination modern kernel (3.14.1+ or the 3.15 tree) and the previous firmware release, things were better, but I'd still have to reconnect maybe once or twice a day - and it never picked the 'best' AP (ie - my signal would always be relatively weak, even though there is an AP about 30 feet away from my desk). Installed this firmware with a build of 3.15, rebooted, and I've got a nice strong signal right off the bat:
signal: -55 [-55] dBm signal avg: -54 [-54] dBm tx bitrate: 780.0 MBit/s VHT-MCS 8 80MHz short GI VHT-NSS 2 rx bitrate: 702.0 MBit/s VHT-MCS 8 80MHz VHT-NSS 2 It'll be interesting to see if it keeps on helping. ;) Thanks! -Nate -- 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
