This script was developed as a workaround for a USB Wi-Fi adapter that was not working properly and got back to work when disconnected and reconnected.
Only tested on GNU/Linux Debian based distros.
The bash script checks for a specified USB device name that can be edited in the variable CURRENT_USB_BUS and CURRENT_USB_PORT inside wifi_check.sh.
The installer.sh script needs to run as superuser in order to create the required .service files.
You can run the following commands to install the script:
chmod +x installer.sh
sudo ./installer.sh
reboot
Run the following command to add the script to your CLI:
sudo mv adapter_reset.sh /bin/
Now you can type "adapter", press Tab and the CLI will autofill the command.
Please note that the name of the adapter inside the script might need to be adjusted.
Insert the following code inside /etc/systemd/system/wifi_reset.service:
[Unit]
Description=Wi-Fi Reset Script
[Service]
ExecStart=/path/to/your/script.sh
Restart=always
User=root
[Install]
WantedBy=default.target
Now enable and add the script to the boot list:
sudo systemctl enable wifi_reset.service
sudo systemctl start wifi_reset.service
Check if it is running smoothly with the following command:
sudo systemctl status wifi_reset.service
Finally, remember to reboot the computer afterward to ensure it was correctly added to the booting processes list.
The reduce_log.sh script is used to remove a specific amount of lines from the log file in order to ensure it does not get too big. Per standard behavior, it checks if the log file is bigger than 100 KB and if it is it removes the first 615 lines of the log (close to 50 KB of data).
