Laptop keeps disconnecting from WIFI

[stevef]

First thing I would do is try to get a bit more information from the log.
Boot as normal.
Open a terminal by pressing Ctrl Alt and T together.
Maximise the window and run this command to show your network interface names.

Code:

iwconfig

Make a note of the wifi adaptor's name - typically it will be on the same line as your wifi network name.

Wait for the problem to occur and make a note of the time it happens.

When running the next command, replace <your-wifi-adaptor> with the name you noted from iwconfig.

Run this command to see what your system has logged which references the adaptor name.

Code:

journalctl -b | grep <your-wifi-adaptor>

Review the output - look for any events that are logged around the time the disconnect occurred.

If there is anything interesting, repeat the same command saving the output to a file called 'wifilog.txt' in your home directory.

Code:

journalctl -b | grep <your-wifi-adaptor> > ~/wifilog.txt

Next, run this command to show everything that was logged around the time.
Replace the first <hh:mm> with a time one minute before you noted the problem happening and the second <hh:mm> with a value to capture say 5 minutes worth of events.

Code:

journalctl -b --since <hh:mm> --until <hh:mm>

If there is anything interesting, repeat same command saving the output to a file called 'wholelog.txt' in your home directory.
You can adjust the times so that the since/until window just covers the interesting events.

Code:

journalctl -b --since <hh:mm> --until <hh:mm> > ~/wholelog.txt

You can edit the files to remove any personal information before posting it back.
