• No connection to specific wifi network


    Dear all, I have read dozens of pages but cannot find a solution to my pb. I have 2 WLANS available. One of them has a stronger signal and is faster. This used to be my default connection. After un update, the laptop can no longer connect to this network but does connect to the fainter, slower one. I guess there is something to reset somewhere but I am not able to find the solution. Maybe one of you geeks knows about this issue? Thx very much for your kind help.

  • Needs some Information about your system… Desktop Environment… output of

    $ sudo lspci
    

    and may also system logs:

    echo ---lspci--- > logs && lspci >> logs && echo ---lsusb--- >> logs && lsusb >> logs && echo ---dmesg--- >> logs && dmesg >> logs && echo ---journalctl-b--- >> logs && journalctl -b >> logs && cat logs | curl -F [email protected] https://ptpb.pw/
    

    and give the url this give you inside a terminal…

  • @joekamprad The same router hosts both networks. SSID is the network name, correct?

  • @joekamprad Thx I will read. I quickly installed broadcom-wl-dkms but had to uninstall it because then I had no wifi at all. Maybe I have to uninstall B43-firmware after installing broadcom-wl-dkms?

  • blacklist the unused driver Blacklisting

    Service Set Identifier = SSID
    The broadcasted name of a network connection point…

    looks very strange to me… seems that it reconnects very often with a lot of stuff happening…
    Do you already try to erase/remove the second wifi settings from your profile?
    So that only the one you want connect is aviable?

  • @joekamprad Thx. No I did not remove anything. If I remove the connection I don’t want but which works I will be left with no connection…

    Can you try to disable avahi-daemon to see if this is causing network error on the network you want to use?

    $ sudo systemctl stop avahi-daemon
    

    and try a reconnect to Denmark

  • @longliveantergos said

    After un update,…

    In such cases, my first action is to switch to the lts kernel. And most of the times it has worked. So, have you tried this, too? Not a solution of course but it might spare you the trouble, if this is the culprit and wait for a fix…

  • @anarch Thx. I don’t know how to do that, sorry.

  • $ sudo pacman -S linux-lts

  • @joekamprad Thank you, that does not work, sorry.

  • @joekamprad Nor does switching to the LTS kernel, sorry.

  • @anarch Thx, I did that according to joekamprad’s indications, but nothing changed. Any other good ideas, please?
