No wifi icon showing

How can I add a wifi icon to my top toolbar? I want it to show available wifi networks, and then be able to access them. I am running Ubuntu 22.04 and Mate 1.26.

Hi. I am also using UM 22.04 with Mate 1.26. My top panel looks like this:

The wifi icon is that funnel-shaped icon to the left of the notification "bell" icon. It was installed automatically when I installed UM 22.04. Lef-cclicking it drops down a context menu that shows available APs to connect to.

Can you show us a screen grab of your panel?
