Working with WiFi issues in Ubuntu is very complex, but do not worry, we will explain how this problem can be solved in a few simple steps and you will be able to do that.

Methods to Fix the WiFi issue in Ubuntu

From checking your network settings to updating drivers and configuring system files, we’ve got you covered. Let’s dive in and get your Ubuntu system back on track with a reliable WiFi connection.

1. Restart your Network Manager

Occasionally just a restart of the network manager fixes WiFi-related troubles. Run the following commands in the terminal:

sudo service network-manager restart

Restarting network

If it does not work, try the next step.

2. Check for Driver Updates

WiFi problems might also be initiated by outdated or faulty drivers. Updating might be using present by running this command below into the terminal.

sudo ubuntu-drivers autoinstall

Updating drivers

This could install all available installation drivers for your system. If there are new updates available, once the installation is done, reboot your computer.

3. Disable and re-enable WiFi

The wifi adapter has problems from time to time. Here’s how you can do it:

• This will bring up to the top right corner of your screen a networking icon.
• Select “Edit Connections.”
• Now click on Edit if you are facing the wireless connection problem.
• Press the “Wireless” tab and choose the “Disable” button.
• Then wait a couple of seconds, and press the button Enabled to turn on the Wi-Fi adapter.

4. Edit the Network Manager Configuration File

If following the steps above does not work you may need to edit the network manager configuration file. Now go to the terminal and type the command as-

sudo nano /etc/NetworkManager/NetworkManager.conf

This will open the settings file up in the nano text editor. Go through the config and find the line managed=false, edit that to managed=true. Press ‘Ctrl+X’, then ‘Y’, and finally ‘Enter’ to save the file.’

Restart the network manager with the following command:

sudo service network-manager restart

5. Reset your Router

If you’re having trouble with worse Wi-Fi than you think you should be having, the problem is more likely with your router. Extra step: Reset your router; you can do this by pressing the reset button (usually a small button on the back of the router) with a paperclip for 15-20 seconds. Disable and then connect your Wi-Fi after the reset.

If none of these helps, you might need to go to any other solution or check your Wi-Fi adapter for any problems.

Note: When executing these steps, remember to replace all placeholder strings (e.g YOUR_WIFI_NAME, etc) with the actual values applicable to your system.
