Thor H. Johansen, thank you for reporting this and helping make Ubuntu better.
In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available. Thank you for your help. ** Tags added: bios-outdated-1qcn32ww ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1618267 Title: RTL8821AE abruptly halts all network traffic Status in linux package in Ubuntu: Incomplete Bug description: Computer: Lenovo IdeaPad 110 WiFi AP: Linksys E2500 After a few minutes of mixed Internet use, the WiFi hangs and the interface ceases to pass traffic: 64 bytes from 8.8.8.8: icmp_seq=281 ttl=55 time=12.8 ms 64 bytes from 8.8.8.8: icmp_seq=282 ttl=55 time=12.5 ms 64 bytes from 8.8.8.8: icmp_seq=283 ttl=55 time=58.4 ms 64 bytes from 8.8.8.8: icmp_seq=284 ttl=55 time=68.0 ms 64 bytes from 8.8.8.8: icmp_seq=285 ttl=55 time=65.6 ms ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available ^C --- 8.8.8.8 ping statistics --- 314 packets transmitted, 283 received, 9% packet loss, time 366615ms rtt min/avg/max/mdev = 11.423/177.382/7227.733/806.648 ms, pipe 8 Before the driver hangs, speeds are 30/5 Mbps despite a 75 Mbps WiFi transmit rate and a 70/70 Mbps symmetrical fiber connection in the house. The connection and the router are known to perform better than this with other equipment. Forcing the router into 802.11g mode does, at least at a cursory glance, seem to mitigate the halting problem, but speeds remain abysmal. If there is any kind of technically involved tests I can do to speed up the debugging of this problem, let me know. I have some experience with embedded development in C.
