Wifi dies on other devices after turning on Lenovo Thinkpad with Fedora

Ask Fedora

Hi all,

Hope you are doing well,

I’ve recently installed Fedora on my Lenovo Thinkpad T14, and after installation what I’ve noticed is that as soon as I turn on this laptop the wifi in other devices dies. This didn’t happen when I had W11, and I think that linux somehow now is kind of overloading the router.

Wifi on this laptop works fine, but this issue makes this laptop unusable, since It makes the wifi plummets for all the other devices in my house.

Hopefully you can help me,

Thanks in advance!

Post the output of nmcli connection show --active and ip addr on the ThinkPad.

When you enable the Wi-Fi on the T14, and other devices lose connection, what error messages do they produce/what symptoms do you see and what devices are they? I’m looking to see if the router is being flooded with requests from the T14 and if it’s a cheap piece of equipment, falling over

Obviously this is not normal, and it’s not “a linux thing”. It might be “a configuration thing” but it’s not because this T14 happens to be running linux.

Thank you for your quick response.

There are no error message, but as an example, if I open tiktok or youtube in my phone, it keeps buffering and it cannot be watched. And the same happens to my tv. Same for browsing something.
Something that I forgot to add, yesterday I’ve reinstalled Fedora to see if that fixed the issue, but it didn’t. So consider this as a fresh fresh install.

When you replicate this, and the phone/tv/other stuff seems to buffer and wait forever, is the T14 utterly fine? Responsive and not sluggish?

The config above is entirely normal - it doesn’t appear to be making itself the gateway or a hotspot or anything weird like that; looks perfectly OK.

Let’s see what is in the journal, or at least what appears when you switch wifi on. Try this:

  • turn Wifi off.
  • open a terminal and tun journalctl -f in it - you’ll be able to see the logs written to the journal in real time.
  • let it all calm down a bit so that you’re not being flooded with messages
  • turn on the wi-fi
  • do a bit of “using the other devices” - the stuff that should now be failing - just want to make sure the logs show what is normally happening.
  • turn the wifi off
  • confirm that the other devices burst back into life
  • press CTRL-C to stop the journalctl output
  • paste that output in here as preformatted text using the </> otherwise the formatting is a nightmare.; hopefully there’s not too much of it.

TV/Phone/other stuff are sluggish, it buffers for a while, works for one or few seconds, and buffers again, and repeat. Not the T14, the internet in the laptop works perfectly. Furthermore, to have the issue the laptop it need to be under load, browsing something, watching some video, etc.

Sorry for flooding the forum with the logs.

First log looks fine.

Seconds log also has nothing massively alarming in it. I do note that you’re using MAC address randomization and that avahi is joining the multi-cast network and doing its thing which might be freaking the router out.

Can you confirm what kind of wifi card you have (lspci | grep -i controller should get it)

Secondly, let’s stop avahi and see if it makes any immediate difference. sudo systemctl stop avahi-daemon and then turn the Wi-Fi on. Are you still seeing other devices get choked on the network and buffering?

7

I’ve tried stoping avahi service and the issue persists. It’s less frequent now, or maybe is not flooded enough.
Here below you can find the results of lspci | grep -i controller

cperalta@fedora:~$ lspci | grep -i controller

The predominant issue with this card seems (or seemed to be) the driver crashing and failing on your T14 rather than negatively impacting other devices on the network.

One of the oft-quotes solutions is to disable power saving, which apparently made it more stable. I guess we can try that despite the fact that it doesn’t seem to have any issues itself. Maybe it’s killnig the radios to save power and your router doesn’t like it…

Turn WiFi off, before anything loses its mind.
Turn avahi back on: sudo systemctl start avahi-daemon
Turn powersaving off: sudo iw dev wlp0s20f3 set power_save off (not sure if you’ll need to enable wifi to change this - try it and see).

Give it another whirl.

I’ve tried that, and it didn’t work. Tried applying another energy profile for tuned, it didn’t help either. Also tried to change to 5.8GHz connection and it’s worst.

Beats me then - I can only suggest changing the router out and making sure that you have the latest firmware installed on your kit via fwupdmgr refresh --force && fwupdmgr update.

This sounds a lot like when the LOCAL is set incorrectly for WiFi … US vs country 00 or some other mismatch …

Try this:
sudo iw reg set US
sudo iw reg get

If this is only occurring when the laptop is under a load (network load) then it may be a factor of the bandwidth available from your ISP. Those with limited bandwidth often see conflicts when multiple devices are using the internet.

Very odd that this only happens on Linux. I suggest:

  1. Update the firmware on the router if you haven’t already
  2. Update the laptop’s BIOS and Management Engine firmware
  3. Check the logs on your router during the time when you use wifi and the other devices are disrupted, it may give you an idea of what’s going on…

A brute force way of solving this could involve splitting your wireless network between the 2.4 and 5 GHz bands - your laptop can use one of them, and the other devices the other, assuming this is some sort of wireless incompatibility issue. The downside is that the 2.4 GHz band is slower.

Disable IPv6 for your wi-fi settings for your laptop.Settings—Wi-Fi your_wi-fi :gear: IPv6 default is automatic change to disable save it and check other devices

Sounds like your Lenovo T14 with Fedora is somehow overloading your Wi-Fi. That would explain why other devices lose connection when it’s on. Have you checked which Wi-Fi driver Fedora is using, Sometimes the generic ones can cause problems. Another thing that helps is turning off Wi-Fi power management, it can be a bit aggressive on Linux.
Also, if your router supports 5 GHz, maybe try putting the hinkpad on 5 GHz and leave other devices on 2.4 GHz. It can reduce interference a lot. Updating Fedora and your Wi-Fi firmware can help too.
