I use ubuntu 18.10 on my computer and I've been getting a weird error since a few days ago. Suddenly, my network icon turns into the version with "?", and I can't acess some websites. No problem on other devices, only on the computer. I'm using a wired connection, and don't have any idea of what could be causing the error.

  It means that you've lost Internet connectivity. Assuming that you're using ethernet... check your cabling first. If you're using wireless, try a stronger signal network.

  Try this now, so you know how it works... in terminal type ping 192.168.0.1. Observe that you're getting return pings, and the time values. Control-c to stop the pings. When you see the ?, indicating that you've lost connection, do the ping again, and see if you recognize the pattern. Report back.
