• No wifi connection to usual network anymore


    Hi to all of you out there and thx for the help you provide. I have 2 wifi networks to which I can connect, but by default i use the one that has a stronger signal. Suddenly, without apparent reason, the connection to the default network is not possible anymore, even manually. The laptop will only connect to the 2nd network which is slow.
    Here is some info, I hope it helps:

  • Sometimes if you go into network manager and delete your connection>reboot>reconnect to it, it may work. I have had the same issue in other distros and have done this action with success.

  • @euge Thx, I’ve tried that - without success. And this particular network is up, I have other devices connected to it. Has anyone a clue?
