Hello, I’m experiencing a network problem.
Today, when I try to connect to the internet, I get the following error.
It’s worth mentioning that the connection was working properly before, but today this issue started occurring. What could be causing it?
Whilst I’m no “expert” on networking, but as a first guess it’s possible you’re on a crowded channel.
As a case in point, I have purposely set my router to a non-crowded channel and, after a firmware update, found it was yet again squeezing in with all the neighbours.
A tool like linssid can help with that so you can set your router to a clear(er) channel.
It will of course help if you can provide some system information. The recommended way is via a Terminal window, issuing:
inxi -zv8
Make sure you select and copy all the text output, before pasting here, as it’s easy to miss something.
… please use the code formatting (the </> button at the top of the Reply window after highlighting the pasted Terminal output, or the three backticks ``` on lines above and below the pasted text).
Note: This output is privacy-filtered using the above command.
Cheers!
And if you don’t want to install anything additional, you can do something similar with nmcli dev wifi list.
Your syslog will likely give you more information:
journalctl --boot --no-pager --grep "NetworkManager"
