Troubleshooting WiFi Connectivity Issues on Parrot OS

If your WiFi is not working on Parrot OS, there could be several potential issues. Here are some steps to troubleshoot and resolve the problem:

1. Check Hardware

Ensure that the physical WiFi switch on your laptop is turned on, and that Airplane mode is not enabled.

2. Check Network Settings

Look for the Network Manager icon in the system tray. Make sure WiFi is enabled. Then click on the Network Manager icon to see if your WiFi network appears in the list of available networks.

3. Install Drivers

Open a terminal and check if your WiFi adapter is recognized:

lspci -nnk | grep -iA3 net

If it's listed but not working, you may need to install the appropriate drivers. You can do this using:

sudo apt updatesudo apt install firmware-linux-nonfree

4. Restart Network Services

Restart the Network Manager service:

sudo systemctl restart NetworkManager

5. Check Logs

Check system logs for any error messages related to networking:

dmesg | grep -i wlan

or

journalctl -xe | grep NetworkManager

6. Disable Power Management

Sometimes power management settings can interfere with WiFi. You can disable it by adding the following line to the configuration file:

sudo nano 

Change wifi.powersave 3 to wifi.powersave 2, then save and exit.

7. Update System

Ensure your system is fully updated:

sudo apt updatesudo apt upgrade

8. Reboot

Reboot your system to apply any changes.

9. Use Terminal

If the GUI is not working, you can connect to a WiFi network via the terminal using:

nmcli dev wifi list

Then connect with:

nmcli dev wifi connect

10. Check for Blocked Devices

Occasionally, devices can be blocked. Check with:

rfkill list

If your WiFi is blocked, you can unblock it using:

sudo rfkill unblock wifi

Following these steps should help resolve most WiFi connectivity issues on Parrot OS. If you've gone through these steps and are still having issues, please provide more details about your hardware and any error messages you encounter. This will help in diagnosing the problem further.
