3.2.0 is not interesting. It should not include other changes except some security fixes. Please use 3.12 from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/ or better test latest ubuntu relase, since different software parts can couse issue. Right now i tested my TL-WN822N v2 (AR7010+9287) on Ubuntu 13.10. It was able to transfer 6GB without any problems or loosing connection. >>From my observations, the issue happens also when I am using a VPN > trough OpenVPN. Can you please describe it more detailed. Some users reported that Keep alive setting of the AccessPoint was reason similar issue. If Ubuntu 13.10 have same problem, i will need more data: - dmesg - iw dev wlan0 scan dump - info about AccesPoint causing problems: name, version, firmware. - lspci and "lsusb -t" -- Regards, Oleksij -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1049383 Title: ath9k_usb: TL-WN821N v3 (AR7010+9287) Connection drops Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Triaged Bug description: Hi. The connection with this device is fast and stable, but seems to drop after a certain amount of data has been transmitted. The easiest way to reproduce it is to download something large. I can always reproduce it by downloading a torrent. After about 300-400MB, it seems like the wireless dongle hangs and the connection doesn't work anymore. At this point, network commands such as iwconfig freeze, and it's also impossible to reboot or turn off the computer. However, if the wireless dongle is unplugged and plugged again, everything's back to normal. The module is set with nohwcrypt=1. If this option is not set, the connection drops much faster. Also, I've noticed that the latency is lower with nohwcrypt=1 (using speedtest.net, the latency without hardware encryption is consistently 3 times less).
