When I opened Network manager, I could see the WiFi networks of my neighbours but not mine ! My Wifi network is provided by a Freebox (french provider Free) and choose automatically the channel for the Wifi network (n type). At home, it was channel n° 13. The neighbours were on channel 6. So I changed the setup of my box manually to channel 11 and the computer can see again my network and connect without problem ! Of course, this problem didn't happen with the 20.10 version : it was connected on channel 13 before the upgrade ! So it seems that Ubuntu 21.04 is unable to connect to a network on channel 13 !
