Problem The network icon in the taskbar has disappeared


Good morning. I installed win 11 on an older desktop with a clean install. Everything is fine but...the network icon in the lower right side near the clock has disappeared. I tried several options to bring it to its place, but I didn't succeed. Please, if anyone knows how to do it, please tell me: Thank you!
The network works normally, the PC connects to the Internet. Also tried with Firefox, Chrome, Edge...
What can i do?
