Is there a wifi-menu (from Arch Linux) equivalent in Ubuntu?

Solution 1:

A good equivalent in Debian/Ubuntu is wicd-curses.

Just remember to input the WPA password BEFORE trying to connect to the network:

1. Highlight the WiFi you want to connect to
2. Press RightArrow to configure the network
3. The last option is the password. Input the password
4. Save
5. Press ENTER on the network list to connect automagically.

You can even configure it to connect automatically next time it sees the network.

Solution 2:

$ sudo apt update

$ sudo apt install netctl -y

$ sudo wifi -menu -y

If you ask me, a lot of these extravagant processes put in place other than my above are simply uncalled for.

Netplan has the most stringent punctuation, and I advise new users against it. But only if they if have an Ethernet handy in order to install netctl.
