rt2800usb - Slow and unstable wireless connection on the last few days

A few days ago I started to experience a really slow (about 1/3 of what used to be) and unstable wireless connection. My first thought was that it was just another ISP issue (unfortunately a common issue here...), but as the problem persisted I decided to investigate.
After a few tests it was possible to conclude that bandwidth intensive tasks, like video streaming and long downloads, were the cause of instability. After a few minutes of such tasks the connection just dropped and the wireless adapter was unable to find the network. It was necessary to switch it off and on again to reconnect.

This is the output of dmesg before the disconnection:

[49336.744337] wlan0: authenticate with 18:a6:f7:9c:a9:e8
[49336.779315] wlan0: send auth to 18:a6:f7:9c:a9:e8 (try 1/3)

And this is the output of dmesg after the disconnection:

After a few searches, I believe this is a problem with the rt2800usb driver due to  this post of a similar issue, but apparently just a kernel update solved this.

I've tried to turn off hardware encryption, but the problem persists.

Anyway, thanks in advance for any help.

Re: rt2800usb - Slow and unstable wireless connection on the last few days

a kernel update solved this

You can try a newer kernel version in BunsenLabs by following this guide:

https://forums.bunsenlabs.org/viewtopic.php?id=1257

You will also need the backported firmware:

sudo apt install firmware-misc-nonfree

Re: rt2800usb - Slow and unstable wireless connection on the last few days

in case the linux-centric solution does not work:
i experienced very similar connectivity problems recently.
i went into my router and there it said that it chooses the wifi channel automatically.
it even told me that for the currently chosen channel there's considerable interference, but apparently wasn't clever enough to change to a different channel.
which i did manually, and now the connection is strong & stable.

Thanks for your reply!

Did that, but the new kernel boots with no video

Just in case, this is the respective dmesg's output (sorry for not filtering it, I have no idea on which information is relevant and which is not):

Re: rt2800usb - Slow and unstable wireless connection on the last few days

in case the linux-centric solution does not work:
i experienced very similar connectivity problems recently.
i went into my router and there it said that it chooses the wifi channel automatically.
it even told me that for the currently chosen channel there's considerable interference, but apparently wasn't clever enough to change to a different channel.
which i did manually, and now the connection is strong & stable.

Thank you for the reply

This is not happening on windows, so I think it is probably something related with the driver.

Re: rt2800usb - Slow and unstable wireless connection on the last few days

Did that, but the new kernel boots with no video

Ooops, sorry — I should have mentioned that the old kernel will still be available via the "Advanced Options" boot sub-menu.

Are you using proprietary NVidia drivers by any chance?

This should list your video hardware and drivers:

lspci -knn | grep -A2 '\''[030[02]\]'

sorry for not filtering it, I have no idea on which information is relevant and which is not

No need to apologise, un-cropped output is always preferred for that exact reason  O:)

Now excuse me while a trawl through that wall of code...  8o

Re: rt2800usb - Slow and unstable wireless connection on the last few days

Question: why aren't you using the Intel wireless card on the PCI bus?

You can get it working with the backported firmware package, I think:

sudo apt install firmware-iwlwifi/jessie-backports

For your video problem this may be relevant:

[Firmware Bug]: Duplicate ACPI video bus devices for the same VGA controller, please try module parameter "video.allow_duplicates=1"if the current driver doesn't work.

Re: rt2800usb - Slow and unstable wireless connection on the last few days

Ooops, sorry — I should have mentioned that the old kernel will still be available via the "Advanced Options" boot sub-menu.

You mentioned on the other post! Haha

Are you using proprietary NVidia drivers by any chance?

Yes, I'm using AMD Catalyst (fglrx) for an AMD Radeon HD 7700M Series GPU. On this specific output I've set it to use the Intel's GPU, hoping it would be easier to see what's going wrong.

This should list your video hardware and drivers:

lspci -knn | grep -A2 '\''[030[02]\]'

This is the output now:

00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09)
	Subsystem: Dell Device [1028:0572]
	Kernel driver in use: i915

Question: why aren't you using the Intel wireless card on the PCI bus?

Well, the wireless signal is very low on it. The Ralink one is attached to an antenna and was much more stable and fast until a few days back.

[Firmware Bug]: Duplicate ACPI video bus devices for the same VGA controller, please try module parameter "video.allow_duplicates=1"if the current driver doesn't work.

I've noticed those "Firmware Bugs", searched this specific one and didn't find an understandable answer, given my poor knowledge. Now that you mentioned it, I did deepest search and found one! Will try it now.

Now excuse me while a trawl through that wall of code...  8o

Thank you so much!

It doesn't work, the message still. I did this:

...create a file called video.conf in /etc/modprobe.d and put in it the line "options video allow_duplicates=1".

Re: rt2800usb - Slow and unstable wireless connection on the last few days

Ooops, sorry — I should have mentioned that the old kernel will still be available via the "Advanced Options" boot sub-menu.

You mentioned on the other post! Haha

Ah good, one step ahead of myself again

I'm using AMD Catalyst (fglrx) for an AMD Radeon HD 7700M Series GPU

The proprietary drivers need rebuilding to match the new kernel version so if you installed directly from AMD then you will have to re-install them.

A better option may be the new open-source amdgpu driver:

https://packages.debian.org/jessie-back … deo-amdgpu

I'm not sure if it will work with your card but the performance exceeds that of the proprietary blobs in every respect.

Question: why aren't you using the Intel wireless card on the PCI bus?

Well, the wireless signal is very low on it.

The newer kernel and firmware packages may well have fixed that

It may even be that the old kernel will work better now that you have the firmware because the kernel was attempting to load the correct firmware and failing and so must have been falling back to a more generic firmware file that may not work as well.

I installed using apt. Is it a good idea to reconfigure or reinstall it? Maybe from jessie-backports?

Unfortunately my card is not compatible.

This is an interesting observation!

Yes, installing the version from jessie-backports should do it.

Is there a particular reason you are running the blobby drivers?

I have an AMD laptop and fglrx is a buggy memory hog which offers only a small performance gain over the open drivers.

Thanks, i'm going to try it

AMDGPU is not compatible and radeon's performance was terrible a few months back. I bought this notebook in 2013, so probably AMD should not be worrying with this card anymore.

I have an AMD laptop and fglrx is a buggy memory hog which offers only a small performance gain over the open drivers.

In this card it seems to run nice. I can play Counter Strike Global Offensive, for example, at full graphics and have a decent FPS rate. I've had problems with it in the past (temperature reached 102ºC ), but read that it was an incompatibility with Gnome.
Anyway, probably I'm gonna give radeon another chance in the near future, but for now fglrx is going to stay (at least until I'm able to have video with the new kernel haha).

Well...
After a few tests, I came to the conclusion that the best thing to do is to use the PCI adapter. It has a much better performance in 5GHz connection, allowing me to use the full bandwidth.

Can I mark the topic as "Abandoned" or something like that?

Head_on_a_Stick: I'm really sorry for taking your time on this. Thanks so much for your tips, I've learned a lot today!

Re: rt2800usb - Slow and unstable wireless connection on the last few days

So did the backported firmware-iwlwifi package improve the connection for that device?

I agree that sounds like the best option, if you can make it work.

I think we should probably leave it as it is, there are several suggestions that can be tried by others even if we have no definitive solution here.

Apparently just by moving my computer around the bedroom was enough to get an stable connection at the 5GHz network. I gave up the new kernel for now, so no need for the backported firmware.

Anyway, thanks!

Actually, you can use the backported firmware-iwlwifi package with the stock kernel because it does not provide any kernel components, it just drops the files in /lib/firmware

EDIT: you can even just install the .deb directly rather than adding the jessie-backports repositories to your sources.

It was already installed and running with the old kernel.
Airmon-ng output:

Interface	Chipset		Driver

wlan1		Intel AC	iwlwifi - [phy0]

I believe that the new one was unable to load it, due to these lines on dmesg:

[    3.574488] iwlwifi 0000:08:00.0: firmware: failed to load iwlwifi-7260-17.ucode (-2)
[    3.574495] iwlwifi 0000:08:00.0: Direct firmware load for iwlwifi-7260-17.ucode failed with error -2

While looking at dmesg's output, I've noticed those lines

[    2.876642] ACPI Warning: SystemIO range 0x0000000000000428-0x000000000000042F conflicts with OpRegion 0x0000000000000400-0x000000000000047F (\PMIO) (20140424/utaddress-254)
[    2.876649] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

After some superficial reading, I found that ACPI is associated with power management.
So, now I'm wondering if this is something to worry about or if it could have a performance impact. This seems a little off topic to me, maybe was the case of another one?

Thanks!

Re: rt2800usb - Slow and unstable wireless connection on the last few days

ACPI

I get those error messages as well

alpine:~$ uname -a
Linux alpine 4.14.20-0-vanilla #1-Alpine SMP Tue Feb 20 17:52:01 UTC 2018 x86_64 GNU/Linux
alpine:~$

A cursory search suggests they are inconsequential and can be safely ignored.
