My perfectly working Maya box was restarted and now cannot display web pages in Firefox. It responds with "server not found".
I can ping the internal interface of my router and the external interface and the router's gateway which is the next hop along so I have full internet connectivity.
Now for the really funky bit. My netgear router has a test feature where it loads the netgear website in a popup window to show the settings are correct. If it loads an address with the word success appears in the address bar of the popup. If there is an issue then a different address appears. The popup window indicates a successful connection to the net gear site but firefox reports "cannot find server".
Other computers have full internet functionality when connected to the same blue cable so the fault has to lie in the mint box.
There are no proxies set and I have done a "sudo ufw disable". I don't have another browser on the box and with no internet I cannot easily install one.
Does anyone have a clever idea?
