DNS 127.0.1.1 not working because of an unknown issue












0















I have an internet connection through Ethernet LAN cable (connected on interface eth7). My Ubuntu OS shows that internet is connected. However, when I search on the browser, page shows that I am not connected to the internet. I have another Ethernet cable connected to interface eth0. The issue resolves somehow ether by adding:




nameserver 8.8.8.8



nameserver 8.8.4.4




in /etc/resolv.conf file, or removing the cable from eth0 port.



Following results of ifconfig and route are found when both cables are plugged in.
the result of ifconfig:

I had a similar issue and ran into a similar solution here that theJack made.



Putting the following GoogleDNS servers in /etc/dhcp/dhclient.conf (unlike the answer given in the link, you must add the '/dhcp' in Ubuntu) should do the trick:




supersede domain-name-servers 8.8.8.8, 8.8.4.4;
