After ISP outage Ubuntu 24.04.4 will not scan for networks

Kde Plasma

Problem Description:slight_smile:

My ISP went down this morning. I was in a rush to grab a document needed for a Dr’s appointment. I tried connecting once or twice without success. I actually saw the Tray icon for Networks disappear from the tray.

Eventually I realized the Internet was down. I went to my appointment, returned and found it was still down. It took five hours to get it fixed.

When it came back up, I could connect to it again on my IPhone. But not on my Ubuntu system. The network icon still wouldn’t come back even after reboot. No scanning for networks seems to be occurring.

Note: any solutions asking me to install anything will fail until I get WiFi back!

Relevant System Information:
Include any details that might help (e.g., hardware, drivers, or special configurations).

Screenshots or Error Messages:

I’m looking for command line way of getting this back.

nmcli shows the problem. (Sorry it has to be by screenshot but I have no other way.)

Nmcli shows the WiFi device is disabled.

it has a GENERAL.STATE of “20 (unavailable)”

What is the solution?

The command I was looking for is

nmcli radio wifi on

It solved the problem. Somehow I had done something in the GUI to turn it off.

In future, please paste the text rather than an image of text. It’s easier to comment on and easier to read

Just an aside: If you really needed internet connection for that computer you could have connected your phone via USB and used USB tethering. It wouldn’t even impact your data plan because, as you said, the phone had WiFi connection so the USB tethering would just bridge the WiFi to the emulated Ethernet.

Ok, usb tethering. Not familiar with that. I suppose I might have saved the screen text to a file, plugged the phone into a usb port, mounted it as a device, transferred the file, and then pasted the text into my post. Next time I’ll try to remember that.

Thetering means your USB cable acts like an Ethernet cable to the phone (so your phone becomes your Internet router), if your phone is on wlan already your desktop Internet traffic will just be routed through the phone into your wlan (if your wlan would be broken as well you could also fall back to mobile network)

While this works out of the box with all Android phones, to make it work with an iPhone you might need extra packages installed though (not sure if this is still the case, it used to be)…
