i tried to connect to some sketchy wifi and now i cannot connect to good wifi

One, i’m not finding anyone saying that connecting to bus or airport wifi broke wifi on their computer, like seems to have definitely happened to me.

From a forum on an iPhone, which apparently has a habit of claiming passwords don’t work when they are correct, i saw the instruction thanks Jamie! to reset network settings.

So:

nmcli device

This is out of date - https://askubuntu.com/questions/835195/how-do-i-reset-my-network-settings-to-default#835198 - because Ubuntu uses netplan now.

And i have exactly zero configuration in /etc/netplan/, completely empty directory.

/run/netplan/ doesn’t exist.

But in /lib/netplan i have

generate
netplan-dbus

… neither file is readable with a regular text editor, what the hell, they said it would be a simple YAML file?!

Taking this to #netplan IRC.

I tried to connect to wifi on a bus. This caused my session to restart (all programs closed, logged out, like a very fast soft reboot) and ever since i cannot connect to known good wifi networks, it just keeps asking for the password even though the password is correct. Have restarted the computer multiple times. Ubuntu (technically Pop!_OS) 19.10

03:38 Anything i can do in netplan to try to my wifi reception?

Oh boy this is bad.

Super basic question, zero answers.

SOS to System76:

OK this is a weird one even for me.

I tried to connect to wifi on a bus. It brought up the full screen system wifi confirmation screen, and then caused my session to restart (all programs closed, logged out, like a very fast soft reboot). Naturally the WiFi on the bus did not work, ok whatever, but ever since i cannot connect to any regular wifi, including known good wifi networks, it just keeps asking for the password even though the passwords are correct. Have restarted the computer multiple times.

Have verified the WiFi passwords with other devices (and networks were known and had passwords saved correctly), also tried forgetting a network, have turned the wifi on and off, etc.

Ever heard of something like this before?

Like pretty much everyone else, i have no idea how to do anything with network configuration now that it is netplan.

So hoping you all do.

I have exactly zero configuration in /etc/netplan/, completely empty directory.

/run/netplan/ doesn’t exist.

But in /lib/netplan i have

generate
netplan-dbus

… but neither file is readable with a regular text editor.

Netplan IRC never answered, but System76 support helped me out:

sudo apt reinstall network-manager

and then a reboot of the computer seemed to do it
