Can't access any info about network

I just updated from Ubuntu 18.04 to 22.04 and my system now shows no network connection. If I try to access the network tabs on System Settings or Info Center, I get an endless pinwheel and it seems to crash the program (i.e., can't switch to another tab, if I close the program it says it is not responding and won't close). Same with running

lshw -C network

and iwconfig in console - I get no result and eventually I just have to close the console window and kill the process.

I use a Realtek AC1200 USB wireless adaptor. If I run lsusb, it shows up correctly.

I really don't know much about Ubuntu, so any help would be greatly appreciated. This isn't the only thing that's gone wrong with the update, but I want to tackle one problem at a time!

Edit:

lsusb result:

I think this is all correct, but if there were any typos it's probably due to human error, as I had to transcribe it onto my other device. Other than the network adapter, I have a Logitech USB keyboard/mouse and a Nexigo webcam.

Ubuntu 18.04 LTS had two *supported & QA-tested* upgrade paths; to the next release (ie. Ubuntu 18.10), or to the next LTS namely Ubuntu 20.04 LTS. Your description suggests you upgraded using an *unsupported* path, so issues maybe expected. If that's what you did, you might want to consider a re-install. You didn't specify what Ubuntu product you're using (Server, Desktop etc), but Ubuntu Desktop systems can be re-installed without loss of data/configuration & *manually installed* packages will auto-reinstall (where they are available from official Ubuntu repositories).

Please edit your question to show the result of the terminal command: `lsusb` Welcome to Ask Ubuntu.

Did you previously try and fail to install a driver? Please show us: `sudo dkms status` Here is the correct method: https://askubuntu.com/questions/1434501/install-usb-d-link-wifi-disable-onboard-also/1434604#1434604

@chili555 The process just runs indefinitely without returning any result. Another interesting twist that I just noticed: running ANY command with sudo seems to freeze the process. Even running ```

Even running "sudo ls -a", for example, does not return a result and leaves the process running until I close the console window.

I suggest that you search here for "sudo hangs". I regret that I haven't the answer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
