If the switch is broken, you might need to remove the internal wifi card so that the USB wifi will work

Did you try the solution here from thx-1138? https://forums.linuxmint.com/viewtopic.php?t=318876 That doesn't work any more sudo apt install git dkms git clone https://github.com/lwfinger/rtlwifi_new.git cd rtlwifi_new/ git checkout extended git checkout 0a751e3 cd sudo dkms add rtlwifi_new sudo dk...

Can you change the channel the Wifi AP is on to channel 1 - 11? I am sure that drivers for most Broadcom wifi only support channels 1-11 on 2.4 GHz

It is the USB wifi adapter in the computer that is the issue, not the router

I don't think any damage was done installing a driver, post result for

Code: Select all

cat /usr/src/rtl8812au-4.3.8.12175.20140902+dfsg/dkms.conf

From the source code: wifi.powersave can have the following value: NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave NM_SETTING_WIRELESS_POWERSAVE_ENABLE...

What about

Code: Select all

ls /usr/src

What result from terminal for

Code: Select all

mokutil --sb-state; dkms status; lsmod

Try

Code: Select all

sudo dkms uninstall ath-5.3/1
sudo dkms remove ath-5.3/1 --all
sudo rm -r /usc/src/ath-5.3-1
cd ath-5.3
git status
git pull
sudo dkms add .
sudo dkms install ath-5.3/1

See if the change I made makes any difference

Check mokutil --sb-state as Secure Boot needs to be disabled for this to work
Then in terminal do

Code: Select all

sudo apt install dkms git
git clone https://github.com/jeremyb31/ath-5.3.git
sudo dkms add ./ath-5.3
sudo dkms install ath-5.3/1

Reboot

You do not need the entire path for modinfo unless you want info about a specific kernel version

See if running this in terminal to disable wifi power management helps

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service

The backport-iwlwifi won't work with Secure Boot enabled, check mokutil --sb-state
If it is enabled, it must be disabled in BIOS

Any results from terminal for

Code: Select all

dmesg | grep mwifiex

Run these 2 commands in terminal

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
cat wireless-info.txt | nc termbin.com 9999

Post termbin.com URL

Try

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
sudo iwconfig wlp1s0 txpower 20
systemctl restart network-manager.service

Can you assign an IP to the computer on the router? Otherwise you will likely have to do manual IPv4 settings in Network Manager
