WiFi Frequently Disconnects and prompts me for the password

Hi, I’ve been having an issue for over a month now where I have a solid WiFi signal but a few times per day the WiFi disconnects and I get the “Wi-Fi password dialog - KDE Daemon” pop-up prompting me to type in my password. Which it should already know. Here’s some terminal output. I’m happy to provide more, if someone can suggest what else would help diagnose this issue. Any ideas? Thank you.

Hi Throwaway12345,
I found this solution/workaround and it seems it solved the issue on my laptop. At least I haven’t seen the wi-fi password dialog since hours, while it was very frequent on the last days.

forum:
/t/wifi-connection-randomly-disconnects/35520

"you have to open an empty file called wifi_rand_mac.conf on the following directory /etc/NetworkManager/conf.d/
and write the following:
[device]
wifi.scan-rand-mac-address=no
…
Save, Close or Exit and reboot. "

thanks to @pablomhr and @j8a

I came here with the same problem. Just tried the suggested solution, I hope it works. But another question is, why has it started doing this? I’ve been running Manjaro on this laptop for probably a year without this issue. What happened to break it?

My problem started within the last two months. I wonder if it was a recent change that is causing the problem. Manjaro is awesome and this is my only problem!

5

It’s not letting me write to that folder even when I type in my sudo password. Frustrating. I’m still a Linux beginner so this is kind of tricky for me.

6

This is weird, try doing it from the live usb

7

I was able to get the file into the directory using the terminal command to copy. Can’t do it using Dolphin.

Now I’ll have to wait and see if the connection problem goes away.

8

You can use kate to create the file and then when saving it in that location it will ask you for the root password

9

Yeah I made the file in kate. Let me ask a very dumb question…the first line is literally: [device] ? I mean the word “device”, not replace device with my computer name?

10

Yes not replace device with computer name jj

11

Cool, got it thanks. Unfortunately I’ve had two disconnects with passsword request since the reboot…

12

I finally had one day with no disconnections. After lots of Googling I found what (for now) is working…
I disabled IPv6 in my network settings. I used the NetworkManager connection editor to do this (small app/download from Official Repositories).
