My ThinBook with Debian is installed with latest updates given by you.
But it still faces issues with Wi-Fi.
Major issue being, laptop fails to show (and connect) any wi-fi networks available, after rebooting laptop from hibernation. I am forced to shut down and reboot again, after which all the wi-fi networks become suddenly visible (!) and then can connect over wi-fi.
What can be the problem and solution to it?
This seems to be a bug, and I too have noticed a similar issue with Wifi.
Sorry, there is no immediate solution for this. I suggest you try using 'sleep' instead of hibernating, if that helps.
I will try to narrow down the issue and will look for a fix.
