Wi-Fi connections, 2

Let me add some information to my question. I have Ubuntu 20.4 on a laptop used as a desk computer (the laptop is a fairly old Lenovo E545). If I start the laptop in a motel room, I want it to look for all the Wi-Fi signals it can find and allow me to choose among them for my connection. How do I tell it to do this?

Solution 1:

Ubuntu already does this...

1. Click on the set of icons at the right side of the the top bar.

   

2. Click "Wi-Fi Not Connected" to expand it, and click "Select Network"

   

3. From the pop-up dialog, select the network you want to connect to and click the "Connect" button.

   

4. Finally, enter your WIFI password when prompted.

If you need to connect to a captive portal (like a hotel wifi), your web browser should open. If it does not open, you can open your web browser and try to navigate to a site, and you should be prompted to enter your guest credentials.

As an alternative to clicking on the set of icons at the right side of the the top bar, you can also open the "System Settings" app and click on "Wi-Fi" in the left panel to see a list of available wireless networks.
