Well I had after half a year of not using ubuntu half a dozen updates, around 1.9 GB of updates.
I noticed afterwards I had to reinstall the drivers for my antenna, as per here: (Driver for the TP-Link AC600 Archer T2U Nano, on Kubuntu 18.04 Previous fix from June 6 didn't work for me)
Now the antenna is found again. Yet when I open it, it doesn't show any networks available. Even though there should be plenty (not only my own, but also from the neighbours/public bar etc)
On my phone, the same computer windows partition a macbook it all works and I can perfectly fine see them. Also I know for sure it worked in the past.
How can I debug, what can I do? I've uninstalled and reinstalled the drivers and rebooted as well.
