I see many other posts with the same issue but cannot find any solution nor explanation and keep clicking on links endlessly so I would appreciate some guidance on this issue, rather than "just trying" to "Forget the connection" and setting it up again.

What I have tried:

Connection to my home wifi seems fine: Settings > Wifi shows my wifi and the signal strength is "good", an IPv4 Address of, and other normal-looking information.

Typing into my browser opens the "Apache2 Ubuntu Default Page".

Typing into my browser opens up a page with my router configuration.

Result of dig

Result of ip route

default via dev wlp3s0 proto dhcp metric 600 dev wlp3s0 scope link metric 1000 dev wlp3s0 proto kernel scope link src metric 600

Result of ping

PING ( 56(84) bytes of data.
ping: sendmsg: Operation not permitted

Result of ping example.com:

ping: example.com: Name or service not known

Running nmcli dev show wlp3s0 spits a bunch of things, but I don't know what to look for.

I did reboot my computer, with no change.

Note. I do have the ip command on my system (which should be enough for diagnostics), but I do not have any of the following commands that I see in other answers: ifconfig, netstats, route, arp, traceroute (which all seem deprecated?).

  • The problem is external to your network. Is this in a corporate environment, or home environment? Cable or DSL modem, or something else? Have you POWER CYCLED the router/modem?

  • This is my home wifi. There were some weird issues with it, and I power cycled it. I am able to use wifi with several other devices, just not my ubuntu machine. I can try power cycling again, just to see, and forgetting the connection on the computer and setting it up again, but I would prefer tracing the issue as far as I can first.

  • Describe your network configuration. I assume that you have a wireless router (what brand?) connected to a cable/DSL modem? Did you power cycle the modem, and any switches/hubs in your network path? Describe the "weird issues" you were having. It might help me. Are you using Access Control lists in your router?

  • Maybe your ISP is down? That's why you can not ping the outside world.

    @Karlom The problem couldn't have been the ISP as I was able to use the internet on all other devices (laptop, tablets, phones). In conclusion: try POWER CYCLING. Feels a bit brute forcish...

From the comments...

Since you get a proper IP address of, and you can get to the routers admin page at, but you can't ping, the problem must be with your router, or your cable/DSL modem. It is a little strange that you can get to the Internet with some other computers.

You've already rebooted the computer. POWER CYCLE your router AND cable/DSL modem. Wait 15 seconds between powering back on. Power on the modem first, wait 15 seconds, then power on the router.

Retry Internet access.
