1814:3290 Slow connection on RT3290: ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush

[Serhiy]

Previously I thought it was due to low WiFi signal, but I've just compared speeds with my phone in my room and directly below the router. The notebook doesn't get more then half Mbps while phone gets 6 to 8 and wired desktop - above 50. I've also tried changing channels.
Kernel log is filled with
ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush
ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 0 failed to flush

Updated to

and nothing changed. I also getting a disconnect about once per two days on average.

P.S. You have "As well, you don't have to create a new bug report." in the comment. Since it's a standard comment, I guess there is a template that needs an edit.

[Serhiy (xintx-ua)]

I forgot the word "_twice_" in the previous comment.

Serhiy Zahoriya, the request statement was already fixed (it's actually due to how some developer(s) didn't disable paste on touching the top right of my touchpad by default, so when I scroll things get pasted and I don't know about until after something stupid happens like it's pasted twice, yay!).

Despite this, could you please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.17-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Serhiy Zahoriya, did this problem not occur in a release prior to 14.04?

[Serhiy (xintx-ua)]

Just bought the notebook, can't say.

[penalvch (penalvch)]

Serhiy Zahoriya, could you please provide the missing information following https://wiki.ubuntu.com/Kernel/LinuxWireless ?

Gone searching for the drivers on realtek.com

[Serhiy (xintx-ua)]

This: http://ubuntuforums.org/showthread.php?t=2104690&page=4&p=12906524#post12906524
doesn't work. And I've compared the code with official (?) drivers from mediatek.com, it's the same.

[Serhiy (xintx-ua)]

The errors:

[Serhiy (xintx-ua)]

Code from
http://askubuntu.com/questions/455030/ralink-rt3290-wifi-driver-is-not-working-in-ubuntu-14-04/455512#455512
compiled fine and visually increased the speed.
I've also discovered that speedtest-cli is unreliable for measuring the speed on the notebook. Although it's looks like working fine in Arch chroot on the phone.

Getting at least 2MB/s download speeds now as opposed to <1MB before installing the driver.

But now I have tons of
 ===>rt_ioctl_giwscan. 12(12) BSS returned, data->length = 2779
 ===>rt_ioctl_giwscan. 11(11) BSS returned, data->length = 2501
 RT3290_AsicTxAlcGetAutoAgcOffset: Incorrect desired TSSI or current TSSI
in the kernel log.

[Serhiy (xintx-ua)]

And with that driver it stops receiving any data about twice per day. Reconnection helps.

Serhiy Zahoriya, circling back on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1360410/comments/13 a lot of requested information is missing:
3b. What wireless connection type are you using (e.g. 802.11n, 802.11g, etc.)?
If you (actually) adjust any the following does it change anything:
    4a. WiFi type (ex. 802.11n to 802.11g only)
    4b. Encryption Type (ex. WEP, WPA2-PSK TKIP+AES)
10. Could you please test upstream's compat-wireless backports via https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-wireless_from_upstream? Please mention in your report the specific version you tested.
13. Does ndiswrapper work following https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper? Please mention what specific version of ndiswrapper you tested with, and a link to the Windows driver you used in your report. Info <!> If ndiswrapper does not work, you are welcome to file a new bug report by executing at a terminal:

ubuntu-bug ndiswrapper-utils-1.9

[Serhiy (xintx-ua)]

3b. 802.11g
4a. I don't have other 802.11n devices and changing to 802.11b is not exactly solving this problem, quite the opposite.
4b. Tried all of them.
10. There is question about that, please answer it.

And now I can barely watch 720p60 on youtube if I close every other network connection.

Serhiy Zahoriya, could you please test the latest mainline kernel 3.18-rc5 and advise to the results?
