I'm not a regular user of this forum and I'm pretty unskilled in writting commands and all. I tried doing my best reading other posts related to my issue but I found several origins of the issue and, henceforth, several solutions posted, and I can't find which one applies to me. I hope you can help me.
I've upgraded from ubuntu 22.04 to 24.04.01 LTS. The issue I've got is that wifi isn't always working although it's showed that there's is a connection. It still works approximately once every other time, so that's what I've been doing these days: restarting computer until wifi really works.
I read this post and ran the wireless info script. Here is the link to the result in pastebin.
I also read this post, which doesn't seem to come to a final solution.
I tried the solution written in this post. I tried to check the status of systemd-resolved but ended up with an error message: Invalid unit name "systemd-resolved.service~" escaped as "systemd-resolved.serv> Unit systemd-resolved.service\x7e.service could not be found. lines 1-2/2 (END)
I also tried, reading this post, sudo apt install systemd-resolved but apparently I already had the newest version. It switch to "installed automatically" (my traduction from french) but I don't know what it means. Anyway, I still get the same connection issue.
I didn't try much more because I'm afraid to do some damage that I couldn't fix. Would anyone have a solution to this issue? Remember that I'm a newbie and that - in case of code in the terminal - I would really need a fully written solution.
Thanks in advance,
Guillaume
