Related Application and/or Package Version (run apt policy $PACKAGE NAME):
Not sure how to identify it, it's the networking indicator in the top-right of the screen. I'm not too familiar with Gnome's naming scheme; sorry.

Issue/Bug Description:
The network indicator (when you're connected to Ethernet) changes to a disconnected version when you unplug your cable, for example. This indicator fails to update when you plug your cable again; during all this time, I was also connected to Wi-Fi.

Steps to reproduce (if you know):
I'm not 100% sure if these are the exact same steps but I manage to reproduce it during a normal day.

1. Be connected to a Wi-Fi network and also have an Ethernet cable plugged-in.
2. Unplug the Ethernet.
3. Observe the network indicator changes to the cable-disconnected version.
4. Plug the cable again.
5. Observe the network indicator fails to update.
6. No amount of fidget with WiFi or Ethernet brings this indicator back to life; it takes a reboot.

Expected behavior:
That the network indicator correctly displays the status of my network. :)

Other Notes:
I promise I will try to find much more accurate repro steps.
It's worth noting that in the above scenario (Ethernet + Wi-Fi connected), if you unplug your Ethernet cable, Wi-Fi doesn't always pick up right away and most apps start to complain you're now offline (Slack, Chromium, FFox, even terminal with a ping). You have to literally reboot to have networking again. I am not sure if this is related but I don't have Ethernet at this moment to test it better. If needed, I'll file a new bug, but whoever looks at this, keep that in mind :)

For what it's worth, I'm unable to replicate in 19.04 (disco).

Ok, I have reproduced this on 19.04 (disco) (Still Pop!_OS)

I am not connected to wi-fi, but I have Ethernet plugged-in. This happened after resuming from suspend.

I'm in fact sending this through the Ethernet connection that the menu bar reports as unplugged. I think the network indicator is mistakenly showing the Wi-Fi disconnection in the Ethernet indicator.

I'd say this is a bug, because it's unexpected; the Network indicator doesn't look like it's supposed to be a "global connectivity indicator", so the icon is very misleading.

I'm able to reproduce this same behavior in Pop!_OS 19.10. I have a desktop that does not have a wifi adapter and is always wired through Ethernet. Seems to consistently happen when I wake the computer up from sleep, the indicator at top right indicates that the network adapter is still disconnected despite the cable still plugged in and I'm able to access Internet without issue.

A reboot of the PC or just the Gnome shell (ALT+F2, r) always changes the indictator status to show connected.
