WiFi problem

Hi,

I’ve got a strange problem with the WIFI connection.
There is only one wireless network connection where I can’t connect into. When I switch on the same notebook to Windows it works fine. Back to Fedora and it doesn’t connect. There isn’t abny blacklist on the router.

But… a few months ago I’ve tried to configure Internet from a SIM card on my ThinkPad laptop and I’ve installed many different drivers. Maybe I’ve broken something.

I’m wondering… Is there any way to reset/clear every settings connected with wi-fi and bring it back, as it was at the beginning without reinstall Fedora ?

Thanks for every help :wink:

Welcome to aks.:fedora:edora!

How did you install them? If with dnf you have the sudo dnf history to see how you installed id.
And with --reverse you can undo it.

dnf history (super, thanks), but

I’m almost sure that it was via dnf, but I can’t see any of them. Maybe it was with snapd. ;/

snap list
(flatpak list works the same)

No, the snap does not show these installations either. Maybe the other way…

Do you know how to clear ALL network setting ? From terminal ? (I’ve done many times Settings/Wi-Fi/Known Wi-Fi Networks/Forget, but maybe not all settings are removed)

You can check any connection both wired or saved wifi connection on /etc/NetworkManager/system-connections/ directories. Then delete the files named like wifi SID.

Maybe you could also then try to reinstall NetworkManager with sudo dnf reinstall NetworkManager.

I turned on the 5GHz network and it works now. But not with 2.4GHz. All right. I don’t know why 2.4 doesn’t work, your suggestions unfortunately didn’t help.

Thanks for the help. Take care.

  • different SID’s and passwords for 2.4 / 5GHz wifi ?
  • your router offers channel > 11 e.g. “13”, but your box/laptop can’t see channel 13, maybe cause of wrong regdomain setting (in linux) ?

    // Router has channel 6, my regdomain is ok (i guess) :wink:
11
