Wireless disconnects after downloading certain amount bytes

Question

I have a brand new system running Ubuntu 16.04 LTS and Windows 10. My system is up to date. I've tried several things found here, but none of them worked for me.

Basically, my wireless connection dropped disconnects after I downloaded around 400 MB. After that, somehow it went through that limit, but now I won't be able to download more than 1.2 GB. I have power management powered off for my wireless card, but that doesn't help.

I tried with Windows 10 and did not have any issues.

Last thing, trying sudo service network-manager restart or disconnecting won't get my connection back. Only by restarting I would get my connection back.

This is what I got from this post: My wireless/WiFi connection does not work. What information is needed to diagnose the issue?

My wireless info

EDIT: (6/24/18)

I forgot to mention the following:

• I guess I probably used the wrong word. I wanted to say it disconnected instead of dropped. It's not that it will download at a slower speed, but rather won't download at all.

• I just suffer this weird bug with this computer (using Linux). I had a laptop and I didn't experience this disconnections at all with it (it was also dual boot between Ubuntu 16.04 and Windows 10).

• I have a Smart TV, a smart phone and a tablet PC and never suffered any disconnections, though I don't think I have met the 1.2 GB with any of those.

Answer 1

Your paste shows this:

Cell 01 - Address: <MAC 'ATT4mHb53Z' [AC1]>
                    Channel:1
                    Frequency:2.412 GHz (Channel 1)
                    Quality=70/70  Signal level=-40 dBm  
                    Encryption key:on
                    ESSID:"ATT4mHb53Z"
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 18 Mb/s
                              24 Mb/s; 36 Mb/s; 54 Mb/s
                    Bit Rates:6 Mb/s; 9 Mb/s; 12 Mb/s; 48 Mb/s
                    Mode:Master

And this:

Channel occupancy:

      8   APs on   Frequency:2.412 GHz (Channel 1)
      2   APs on   Frequency:2.417 GHz (Channel 2)
      1   APs on   Frequency:2.427 GHz (Channel 4)
      1   APs on   Frequency:2.432 GHz (Channel 5)
      1   APs on   Frequency:2.437 GHz (Channel 6)
      1   APs on   Frequency:2.442 GHz (Channel 7)
      5   APs on   Frequency:2.462 GHz (Channel 11)

Did you select channel 1 intentionally, not realizing that it is the most congested channel in your area? Or, more likely, is your router set to auto-select the channel. This interesting post shows why auto-select is a very bad idea: https://superuser.com/questions/1311149/why-do-wifi-routers-do-such-a-bad-job-of-channel-selection

Please set your router to a fixed channel, ideally channel 6, and tell us if the connectivity is improved.

EDIT: Check all of the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Next, I recommend that your regulatory domain be set explicitly. Check yours:

sudo iw reg get

If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:

sudo iw reg set IS

Of course, substitute your country code if not Iceland. Set it permanently:

sudo nano /etc/default/crda

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save and close the text editor.

Any improvement?

EDIT 2: Please try a driver parameter. From the terminal:

sudo -i
echo "options rt2800pci nohwcrypt=Y"  >  /etc/modprobe.d/rt2800pci.conf
exit

Reboot. Any improvement?

EDIT 3: In you log, we see dozens of entries:

rt2x00queue_flush_queue: Warning - Queue 2 failed to flush

Here is a post that describes your issue exactly; the wireless disconnects and nothing short of a reboot helps: https://bbs.archlinux.org/viewtopic.php?id=237028 Notice that the log messages are the same and there is no real solution. There is a suggestion that it is a hardware issue.

Here is another, with the same log messages; definitely a hardware issue: https://forum.lede-project.org/t/solved-wireless-interruption-on-zyxel-p2812hnu-f1/11088/9

Here is another with no solution: Ubuntu 16.04 Weak WiFi Signal after dual boot Ralink Rt3290

I suggest that you make sure that the card is seating correctly in its PCI slot. If you still have trouble, I suggest that you consider replacing the card. If you do so, be certain to blacklist the driver rt2800pci for the internal device.

Answer 2

From your network info below:

Network controller [0280]: Ralink corp. RT3062 Wireless 802.11n 2T/2R [1814:3062] Subsystem: Ralink corp. RT3062 Wireless 802.11n 2T/2R [1814:3062] Kernel driver in use: rt2800pci

It shows that your wireless interface is RT3062, but it didn't show in your "lsmod list", it seems that this module isn't installed in your computer, so you have to install firmware 'rt3062' first. Hope it helps.
