Checking Wireless Connection Settings

The first step in troubleshooting a wireless connection issue is to check the wireless connection settings. To do this, follow these steps:

4. If the wireless connection is still not visible, try restarting the network manager by running the following command in the terminal:
sudo systemctl restart NetworkManager

Verifying Wireless Hardware

If the wireless connection is still not visible, the next step is to verify the wireless hardware. To do this, follow these steps:

1. Run the following command in the terminal to check if the wireless hardware is recognized:
lspci -nn | grep Network
2. If the wireless hardware is not recognized, try updating the BIOS or firmware of the laptop.

sudo modprobe -r iwlwifi && sudo modprobe iwlwifi
