Leap 15.5: unstable wifi connection

It sometime works, sometime doesn't. This problem is not present on another laptop (Ubuntu) connected to the same wifi router.

Code:

# systemctl restart NetworkManager

did not help.

# systemctl status NetworkManager

Anyone other has please similar problem ?

Start by monitoring NM logging in a terminal

Code:

sudio journaltl -fu NetworkManager

When the connection drops, observe/share the output from around that time.

It is possible to start a wifi connection without NetworkManager, by using wpa_supplicant (for diagnostic purposes). You'd need to stop NetworkManager first, and you may need to install wpa_supplicant-gui as well...

Thank you. Seems to be solved after change of the DNS.

Thanks for the update. Nothing to with unstable wifi connection as the title suggested then.

I'm sorry I'm not sure what exactly you mean.

Well, you mentioned changing DNS was the solution. That has nothing to do with wifi stability. ;)

Every correction / improvement of gammar is welcome. How do you please understand the term "unstable wifi connection" ?

In the context of a wireless connection, it is one where the status is frequently going from associated to dissociated and back again. Usually as a result of interference, weak signal, or excessive roaming.

In any case as you claim that your network issue (due to DNS) is resolved then there is no need to discuss further in this protracted fashion. ;)

Than you for explanation.

I'm sorry DNS change did not help in all cases.
