Wireless disconnects from router [SOLVED]

[tkocou]

I have noticed that at random times, my LM wifi network will disconnect from my router. The disconnect is not an Internet problem. It's an annoyance as a simple reconnect fixes the issue until the next time it occurs. The power management is turned off for the wifi adapter. Has anyone else noticed similar behavior?

Has anyone else noticed similar behavior?

To answer your question: Yes.

[Pjotr]

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- Make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxpmrz

(if you type: the letter F is a capital letter, and don't omit the space after inxi!)

Press Enter.

Copy/paste the output in your next message.

Do the same with the following four commands:

Code: Select all

rfkill list all

Code: Select all

iwconfig

Code: Select all

lsusb

Code: Select all

lspci

Hopefully you can make sense of this data

Thank you for the tips. I am currently using the driver rtl8812au-5.13.2. The first tip is for an earlier version of rtl8812au which no longer works with the latest kernel. I've tried the second tip and will let you know what happens.

[tkocou]

SO much for that second tip. After posting my previous reply, my wifi promptly disconnected me. So I deleted the extra file.

[tkocou]

The fix to this situation was to download the latest driver source code, purge all previous drivers from the hard drive and compile the source as a DKMS driver.
