[SOLVED] TLP messed with my Wifi

I installed TLP, but soon found I could not access the internet anymore. So I uninstalled it again, and also did systemctl disable tlp.service. However, I still cannot access.

The Wifi signal is strong and picked up by EnOS.
What can I do?

Usually it doesn’t do anything like that, but in cases like that with some specific devices, like your wi-fi module, you may need to whitelist it or disable it’s powersaving functionality, to make it easier install tlpui and see those tabs:

  • Network
  • Radio
  • Radio wizard

P.S. To apply settings don’t forget to press Save button on top right :wink:

So, now that I have uninstalled TLP entirely, I should reinstall it, but the tlpui instead of the tlp unit. Correct?

Installing tlpui should automatically install dependencies of it.
Just install tlpui.

Like @mrvictory said, tlpui is just a gui to easily control config file of tlp and it will automatically pull tlp as dependency when you install.

I only recommended tlpui because sometimes it might be overwhelming, if you’re not very familiar with tlp when searching for some options, but you can use it directly by changing /etc/tlp.conf, you can read more about it’s options at https://linrunner.de/tlp/settings.

I am still not clear about this.

Since I uninstalled TLP, there should not be any more obstructions to the WiFi device. Am I wrong?

Oh wait, i misunderstood your post - if you have uninstalled tlp and rebooted (just in case), and after that wi-fi still doesn’t work - then it’s certainly not tlp that is causing your problem.

Can you give us

Have you tried removing and re-adding the connection to Network Manager?

I just did that now, to no avail.

Now, there is 1 odd thing: in one of the browsers I have installed the Hide Me proxy. When it is disabled I cannot access internet, when I enable it, I can access internet!

However, with none of the other browsers, which don’t have Hide Me, I cannot access internet.

Sounds like a DNS issue. Check the contents of /etc/resolv.conf, and whether you can ping an IP address, e.g.

ping -c3 8.8.8.8

This also sounds completely unrelated to TLP.

TLP-DOC, Note:
Power saving mode can cause an unstable Wi-Fi link.

Check your TLP config file, according to this site:
https://linrunner.de/tlp/settings/network.html

Here are my notes (protocol I wrote myself) of installing TLP / TLPUI, because I just wanted to be able to revert things correctly, in case I need to uninstall:

Summary
  • Installed TLP:
    dnf install tlp tlp-rdw

  • Removed conflicting daemon:
    dnf remove power-profiles-daemon

  • Enabled service:
    systemctl enable tlp.service

  • Masked 2 conflicting units:
    systemctl mask systemd-rfkill.service systemd-rfkill.socket

  • See https://linrunner.de/tlp/usage/index.html

  • Installed TLPUI:
    git clone https://github.com/d4nj1/TLPUI
    cd TLPUI

  • To start TLPUI:
    cd TLPUI
    python3 -m tlpui


  • Config-file:
    /etc/tlp.conf

Contents of /etc/resolv.conf:

#Generated by NetworkManager
nameserver ::1

Yes, pinging that address worked.

If it is unrelated to TLP, how come I did not have this problem before TLP was installed?

So, this implies you are not getting a DNS resolver from your router via DHCP. Check your network settings, and check your router.

You may have changed something else at the same time.

Below is a screenshot of the settings. There was no DNS address, so I tried to add one. But even putting the numbers in the box, the Apply button remains greyed out.

Screenshot from 2022-07-10 18-41-04

My router is fine because I am having this conversation with you via my Mac that uses the same router.

As long as you have automatic DNS enabled, you cannot at the same time add another DNS address.

So, what does Jonathon mean by

and what should I check then, and how?

That’s not correct - the additional resolver will be used in addition to any received from DHCP.

Did you press the Plus icon to add the IP address?

Yes, I did. It just adds a 2nd box below for the next DNS address, but the Apply button remains greyed out.
