Need some help...
Nearly 20 year Ubuntu user but never encountered this kind of hassle.
Xubuntu fresh install (no dual boot).
Network manager indicates ethernet and usb wireless adapter are connecting while network monitor indicates incoming signal.
But no way to get on the web.
I would like to have one of them working in order to install lower kernel version (installed is 5.11.0-27-generic).
Does anyone see any sign of problem in the answer given by :
