Lubuntu 20.04 cannot connect to any network after 1 year + of not using my computer

772

I was away from for over a year, and when I turned on my computer, I discovered that I could no longer connect to any networks. When I left the ethernet was working fine. All other devices in the house can connect without issues. These are the steps I have taken:

Checked the cables.
Checked the status of NetworkManager with systemctl. It was running, but I restarted it anywyway and that made no difference.
Tried connecting using wifi. I can see my wifi network and enter my password, but get a disconnect error after a few seconds of trying to connect.
Booted from a Lubuntu bootable USB. Wifi and ethernet both work right off the bat, websites loaded.
Checked my system time. If it's off, it's off by less than 1 minute.
After connecing with the bootable usb, when I restarted into my installation, wifi showed as connected (instead of "connecting" as it did before). However I could not load any pages or ping anything (even my router). After restarting again, all I have seen is the behavior described in #3.

I'm at somewhat of a loss as to what to try next. The usual stuff isn't working.

addendum: Here is a sample of journalctl -b 0 -u NetworkManager output`

Also I checked journalctl again after again trying to plug in my ethernet and bring it up with ip link set. I'm not sure if it is relevant or not.

UPDATE: It all works now! Problem is, I have no idea why as I changed absolutely no configurations. All I did is leave the computer off for a couple hours.

I rebooted and the wifi interface came up and connected, but then disconnected.

I tried plugging the ethernet in again (this time to a different port) and bringing up ip with ip link set. This time it seems to have worked. What is odd though is that the applet icon still shows that I am disconnected. I suspect my problems may not be over.
