I have a dual boot Windows 10 and Ubuntu 20.04 machine. I can connect to Wifi fine on Windows, but when using Ubuntu it disconnects every 10-20 minutes or so. When this happens, I can always get it working again with:

sudo rmmod wl
sudo modprobe wl

I've tried suggestions from similar posts (e.g., disabling IPv6, setting REGDOMAIN=GB in /etc/default/crda and installing linux-firmware), but nothing has worked so far. I'd be very grateful if anybody could help.

Output from lspci -nn -d 14e4:

21:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03)

Output from journalctl" around time of disconnect:

I came across the following post today. Can you try to change your SSID name to all lower cases and see if that fix the issue? I'm not sure what the problem is, but it might worth a try.

In my case the problem started after i set MAc address to random on garuda linux this mess up the wifi on both garuda and windows dual boot, i tried every post i found,nothing worked a clean install of ubuntu fix did not fix it, niether setting mac address back to default fixed the problem. i ended up deleting both windows and garuda, i only left untouch the home partition

sudo iwconfig wlp2s0 power off
cd /etc/pm/
sudo -H gedit wifi_pwr_off

this will open a blank file, copy this to blank file:

#!/bin/sh
/sbin/iwconfig wlp2s0 power off

save the file and close

sudo chmod u+x wifi_pwr_off

done
