[SOLVED] Internet disconnects randomly on TL-WN422G using ath9k_htc on a T430

WanderingUnix · 03-31-2021, 12:12 PM

Hello. I have been having this ploblem with the ath9k_htc driver and have no idea what is causing it. I am using kernel 5.11.10 (self compiled). I had these issues with the standard generic kernel so I moved to a self compiled kernel but it did not seem to fix the issue.

I do not remember which kernel but possibly 5.10.23 was when it started. It would just disconnect completely and without warning. Network manager would display the connection speed as 1mbps but the light would still be flashing as if there was internet.

I have tried:

- disabling hw crypto via a modeprobe option (only a slight boost in bandwith)
- disabling the light on the usb module (makes no difference)
- Switching the port that it used (usb 3 seem to make it worse)
- Disabling intel_iommu (which helped some of the errors but did not solve the issue)
- compiling a newer kernel to see if it fixes it (nope)
- Turn off ipv6 (Nope)

The error would first be a dns related error.
To fix that I simply used unbound with dns over tls which made that issue go away but now the real issue revealed itself which was that the internet just died for no tangible reason

Here is the dmesg. Yes there is alot about my wifi and MAC ADDRESS is just a replacement for my actual mac address.

Here is the result of lsusb

My kernel .config:

Please note I am using linux libre with the latest linux libre scripts.

I am honestly lost at what to do. It could be the usb adapter itself but I just want to check. It could even be my kernel config. I just want someone to help solve this. Thank you!

I have the Qualcomm Atheros 9485 and find it good and hugely reliable. It's not a new device but a stable one.

For a start, I would disable all the encryption, obfuscation and whatever else is going on, and get back to a plain simple wifi connection, so we can make sense of that. If you're posting on public forum, I presume you're not spying for aliens or doing anything criminal

.

Run this command

Code:

[sudo] iwlist wlan0 scan |grep -A2 Quality

replacing 'wlan0' with the relevant wifi interface name if needed. Post the results. I'm getting results as low as 16/70 or -94dBm. What the lowest you are getting?

I decided to use a spare intel wifi stick for a few days.

I see the same disconnection issues. Another thing I forgot to mention is that after an hour or two, the wifi module that is loaded completely fails to load and I get a stack trace in dmesg.

I'll make a new thread for the intel stick as this is very strange. The connection quality according to networkmanager is 51%

Sorry I could not reply sooner. I was busy with stuff.

Have you done that yet? There's no point in me answering in this thread if you haven't. If you have not, do it now.

51% = -50-60 dBm. Presuming you're not tripping over you own encryption (which I don't yet know) you can eliminate hardware as a source of your problems. A quality of 51% will not give you full speed but fairly ok speeds. You've tried two wifi units.

What else could be causing the problems? Is there a timeout on idle set?

WanderingUnix · 04-06-2021, 07:12 AM

Yes I have disabled everything like encryption and obfuscation.

No there is no timeout on idle but I did find this in dmesg.

Seems to be a ploblem with the firmware maybe? This happens to the wifi when the computer is completely idle and at random. I saw other people who had this problem but no solutions. Only an old kernel issue that was fixed in a old kernel. Ill see if putting a new router fixes the ploblem but I think it could be a kernel issue. I have not tampered much with wifi related options. Ill try 5.4 and 4.19 to see if they cause any issues.

From the look of that, you are using the (Realtek) iwlwifi module to drive the Qualcomm Atheros wifi card, or possibly the intel usb thingy you've got. No wonder it's making strange!

Device numbers are or should be issued in the order they are discovered.I presume your Qualcomm Atheros wifi is internal, and your intel usb device external. So

wlan0 should be Qualcomm
wlan1 should be intel, and no others should exist.

Is there a problem with that reasoning. Go after why a Qualcomm card is loading a Realtek module. What module is the Intel one loading?

The way that seems to be set up, the strange thing isn't that it goes on the blink; the strange thing is that it ever worked. We may get out of this with some artful editing of /etc/modprobe.conf (if such still exists).

Ok I have finally fixed it!
I used 4.19 and that seem to clear the disconnections. Must be a problem with newer kernel.
I tested by downloading multiple bits of data (games, videos) and watching youtube) and it never disconnected!
I will mark it as solved.
JUst to note: My TL-WN422G is disconnected an I am using the intel wifi. I tested that and it also works. Thank you!

Good to hear That's weird behaviour, like something is showing in modules blacklist, or not showing in the initrd.
