Browser problems

[DorianCottam]

When using the Epiphany Web Browser every search comes up with:

The website at https://duckduckgo.com/ (then the search) seems to be unavailable. The precise error was:

Cannot resolve hostname (duckduckgo.com)

It could be temporarily switched off or moved to a new address. Don't forget to check that your internet connection is working correctly.

Why is this so?

Thank you,

Dorian

Can you connect to any website at all?

How is your Pi connecting to the internet? If you don't have an internet connection, then the browser will run but will not be able to find any websites.

Try the following commands
ip addr show
ip route
ping -c3 $(ip route | awk '/default/ {print $3}')
ping -c3 8.8.8.8
ping -c3 google.com
cat /etc/resolv.conf
Post the results here, if possible. Or take a photo of the screen, upload that to http://imgur.com and post a link to it here.

Hi I did not post the question, but I have the smae problem. I just bought a Pi 3 Model B and I am seemingly able to connect to the LAN. I can see the classic internet connected chevron in the top right hand corner, with a 100% signal strength. I was able to run your commands... here are the responses, all carefully typed in...

So you can reach the router, but the router isn't forwarding your IP traffic on to the public internet. Start by rebooting your router, then hit it hard with a very big stick.

It's a virgin broadband router... Have you got a better solution?

Hit it extremely hard with an enormous stick. It's not routing.

After you've rebooted the router, then try rebooting your Raspberry.

Hi I have rebooted the virgin modem. No joy
I have reinstalled the NOOBS software without configuring anything so I could run a cable into the hub no joy
however when i ping 8.8.8.8. and Google.com I get 3 packets transmitted, 3 recieved 0% packet loss in both cases.
I get the same whether I turn the wifi on or off.
Any thoughts?
I got a new wifi box coming tomorrow, that might make a difference.

[Drclohite]

It is working. I randomly selected the pi help mneu which turned out to be a web resource.

It may have been that I was looking for google.com and google switched to a https server and the browser on the pi did not like the security....

Works on wifi and cat 5 cable

Could have been the reloaded NOOBS, or the restarted router. I don't know which.

Will turn it all off and restart tomorrow!

[Drclohite]

Seems I have to reboot the router every time. Is there a better solution?

As I am turning the whole house off and the many other devices connected... Much disturbance....

[Drclohite]

I noticed that as I shut down the screen breifly says Discarding DNS settings, or something similar. Is there a way I can preserve those settings?

Otherwise I am thinking of using a seperate dongle just for the pi, or trying to connect to the internet via my phone. Both of which are not ideal, when I have wifi in the whole house.

I can't be the first with this issue, how have you made it work?

[DougieLawson]

What would that achieve? DNS is an optimised, high speed, distrubuted hierarchical database. The time needed to resolve any address to any IP address is measured in microseconds.

[Drclohite]

I am not sure what it would achieve? I was hoping to find a way to make sure that the device logged in to the internet each time without resetting the hardware. However, this afternoon, it just did. I hope it continues.

Thanks for your help in making me think about this Dougie

Your Raspberry will connect automagically if your WiFi credentials are stored correctly and the WiFi is in range. If you wire it with a cat5 cable it's 100% guaranteed to connect as soon as the OS boots.
