Intermittent wifi issues with NetworkManager

I built a new system a while back, and it's always had a bit of an issue with the wifi. I'm trying to narrow down the cause.

Basically, my network connection is absolutely fine most of the time. I can play online games, watch videos, etc without any fuss.

However, randomly throughout the day (1 to 2 times), my connection will be haywire for about 30 mins.

The connection does not drop completely, NetworkManager is still connected to the correct AP. But when I run a speedtest, (if it loads at all), gives me a speed below 1mbps.

After a few minutes, it will "fix itself", and the speedtest rockets back up to my usual 40-60 mbps range. Sometimes the test will start at 1mbps, and be back at 50 by the time it finishes.

But this only lasts for a minute, because before I know it it's down to 1mbps again. This continues for roughly 30 mins before the issue is "permanently fixed" and speed goes back to normal for the rest of the day.

Some possible causes:

  • I am on WifI. This is not ideal, but I don't have a long ass ethernet cable

  • I moved my PC farther from the router. Not my choice, but it happened nonetheless.

  • I am using a broadcom wifi chipset which is known to have issues

Here are some lines in journalctl which seemed relevant:

as it fails to reconnect to the wifi network. But lo and behold, just try enough times and it just fixes itself. Very annoying.

I think this is the first message upon reconnect

When I run

 lspci 

I get

Network controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter (rev 03)

Which is my wifi card

Re: Intermittent wifi issues with NetworkManager

Disable/stop the wpa_supplicant service (NM will run wap_supplicant/iwd itself and the two will get in a race over the NIC, knocking each other out)

Re: Intermittent wifi issues with NetworkManager

Update: Everything seemed to work ok, but after going out of town for a few days and returning, the behavior is back with a vengeance.

I ran

sudo systemctl disable wpa_supplicant

and

sudo systemctl stop wpa_supplicant

But when I run


sudo systemctl status wpa_supplicant

I get

I have no idea how or why it is being run, or what the main issue is really.

Re: Intermittent wifi issues with NetworkManager

NM uses wpa_supplicant to establish the WIFI carrier and I assume it starts it through the service (notice that the wpa_supplicant PID is > the NM PID)
=> updated journal?

So this is the second time today this is happening, around 6:50 local time. Here is all the journal for that time frame. Some things seem interesting...

Re: Intermittent wifi issues with NetworkManager

Upon further research, it seems like my issue might be related to docker-compose?

https://bbs.archlinux.org/viewtopic.php?id=247020
https://unix.stackexchange.com/question … k-on-linux

Here is the output of docker ps

Could it be the sopel container? It seems to be the newest, it could be restarting itself?

Re: Intermittent wifi issues with NetworkManager

Could also be the other way round (the container restarts for the network loss)
The journal starts w/ a virtual device being detached from the bridge device, then a lot of docker stuff, then a new  virtual device is setup.

The most interesting bits should be slightly ahead of the first posted line (ie. *why* all of this is happening)

But if everytime you encounter a network issue the same container just restarted, I'd say the container is at the root of this.

Hmm, I've killed a few of the containers I no longer need, but I'm still getting the issue!

This output is sandwiched on either side by LOTS of nextcloud logs, which are basically always there as I am constantly editing synced files. This is the only activity during the error I could see

Re: Intermittent wifi issues with NetworkManager

The excerpt seems to show NM in the middle of a re-connection. It does not fully explain what's going on, let alone why.
Please post the entire journal, not some random fractions. You can use a pastebin service (the first link in my signature explains how to directly pipe the output of a command into one)

Re: Intermittent wifi issues with NetworkManager

Even my journal from this boot alone is too big to paste to ix.io, codepad, and xclip complains when I try and copy the whole thing... Let my see if I can get something working

Re: Intermittent wifi issues with NetworkManager

You'll at least have to widen the timeframe significantly (an hour around the incident should certainly suffice)

Ok, here is the entire journal starting from 10AM Local to right now (11:57 AM). The issues are happening at roughly 11:26

Re: Intermittent wifi issues with NetworkManager

So, what's obvious is that nextcloud is going nuts over sync'ing a couple of files.
NM only logs the loss of the global connection ("no internet") which is resolved after a minute, but could be outside the system (eg. on the router)

I'd first fix the nextcloud situation.

Re: Intermittent wifi issues with NetworkManager

Interesting. I have absolutely no clue what is going on with NextCloud, it seems to be working as far as I can tell...

Looking through my logs shows it's failing to upload/sync a single file. I am getting the 423 LOCKED server response when I try to delete the file... Obviously this is outside the scope of this original thread but this keeps getting more and more frustrating!

I have no idea why/if this failure is causing my network outages, but I might as well clean the issue up anyways and clear out my journal...

Re: Intermittent wifi issues with NetworkManager

I disabled file locking serverside, in case anyone else comes across this issue, just add

'filelocking.enabled' => false,

to your config.php file. This allowed me to delete the file that was locked for some reason. I will closely monitor my logs, and next time I experience network issues I will paste the journal, hopefully free of NC messages.

Re: Intermittent wifi issues with NetworkManager

Still getting the issue today unfortunately. Both of them, though i'm not sure they're related. Nextcloud seems to have issues syncing files that are auto-generated as I am writing LaTeX on my machine. But the last log about that is at least an hour before my issues kicked in, which was roughly 19:10. It "fixed" at 19:19.

Re: Intermittent wifi issues with NetworkManager

NM just pretty much suddenly moves to CONNECTED_SITE.
Can you test whether this also happens w/ a wired connection? (Just temporarily to figure whether this is WIFI related at all)
Do you have a bluetooth device? Or other wifi devices nearby that could interfere?
Can you access the router/AP logs to check whether it cut the connection?
Can you test the speed on the LAN (eg. wget a file from another device in the subnet)?

Re: Intermittent wifi issues with NetworkManager

To answer your questions:

* I will try to move to a wired connection soon, i'll probably have time this weekend
* I do have a bluetooth device, an RK 61 bluetooth keyboard. It is annoying as it refuses to stay connected to the bluetooth if I leave it alone for 20+ minutes.
* I also have the Broadcom BCM4360 chipset, which is known to have issues. I might try tearing the wifi card out of my old build, which didn't have these issues. (it had other network issues but i digress)
* I'll poke around the awful comcast router interface and see if I can find logs. Although I have no reason to see why this machine in particular (out of lots of devices, a few of which are running Arch as well) would be blocked.
* I have run multiple speedtests on other devices and haven't seen any slowdowns.

Lines like this makes me think it's something to do with the card
