[Kernel-packages] [Bug 1622293] Re: rtl8821ae WiFI does not work
Summary; my own rtl8821ae frequent connection lost problem was fixed by
upstream patch b8b8b16352cd ("rtlwifi: rtl8821ae: Fix connection lost
problem") merged for 4.14-rc4.
I've recently fixed a problem very much like the problems reported in
this bug. In particular the loss of WiFi scan results, and the
connection loss on a burst of download data. Workaround was to turn
wireless off then on again (using rfkill), or reboot. What I did was
(a) test several ubuntu kernels to find which ones were affected,
(b) using git bisect, tested several custom kernels, and proved my
problem began with a single commit 40b368af4b75 ("rtlwifi: Fix alignment
issues"),
(c) worked with upstream to determine a likely cause; the commit wasn't
widely tested,
(d) proved through testing that the BIOS can have an effect; because the
rtl8821ae driver does not reset the card, but inherits the card in
whatever state the BIOS left it. This can randomise problem reports.
(e) proved that a power down and reboot can have a different effect to a
warm reboot; some of the wireless card device registers are unchanged on
warm reboot. This can randomise problem reports.
Hope that helps.

Anton Polukhin, as per http://www.tp-linkru.com/download/TL- WR841N_V9.html#Firmware an update to your router's buggy, insecure, and outdated firmware is available (150331). When you update to this following how does this improve the situation? For more on firmware updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note you don't have to create a new report. It is most helpful that after the firmware is updated, if the problem is still reproducible: 1) Please provide a screenshot of the router showing the firmware. 2) Please make a comment specifically advising on how this improves the situation. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

[Kernel-packages] [Bug 1622293] Re: rtl8821ae WiFI does not work on Ubuntu 16.04
2) Problems with kernel 4.8-rc6 are mostly the same: tl8821ae does not loose the connection (at least network manager does not display that), but the speed drops down to 50KB/s really often. Instead of 2.5 MB/s connection speed, I have an average of ~100KB/s, with rare peeks up to 2.5MB/s and common dropdowns to less that 50KB/s. Latency is huge: if I pause downloading at the speed of 50KB/s and try to download some very simple web page, it may take a few minutes. ** Tags added: kernel-bug-exists-upstream-4.8-rc6 -- 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/1622293 Title: rtl8821ae WiFI does not work on Ubuntu 16.04 Status in linux package in Ubuntu: Incomplete Bug description: rtl8821ae does not work out-of the box on Ubuntu 16.04.

[Kernel-packages] [Bug 1622293] Re: rtl8821ae WiFI does not work on Ubuntu 16.04
Anton Polukhin, 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 removed: rtl8821ae ** Tags added: cecn43ww ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** 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/1622293 Title: rtl8821ae WiFI does not work on Ubuntu 16.04 Status in linux package in Ubuntu: Incomplete Bug description: rtl8821ae does not work out-of the box on Ubuntu 16.04.
