To prioritize wireless network connections on Ubuntu, you can follow these steps:

1. Open the terminal by pressing "Ctrl+Alt+T" on your keyboard.
2. Type the command "nm-connection-editor" in the terminal and press Enter. This will open the Network Connections window.
3. Click on the "Wireless" tab to see the list of wireless networks that you have connected to in the past.
4. Click on the network that you want to prioritize and click the "Edit" button.
5. In the "Wi-Fi" tab, scroll down to the "Priority" section and enter a higher number for the network that you want to prioritize. For example, if you want to prioritize a network with a priority of 1, enter a priority of 2 or higher for the other networks.
6. Click "Save" to save the changes.
7. Repeat steps 4-6 for each network that you want to prioritize.
8. Once you have set the priorities for all the networks, click "Close" to close the Network Connections window.

After you have prioritized the wireless networks, Ubuntu will automatically connect to the network with the highest priority when it is available.
