I'm new to Raspberry Pi and have had an issue which has bugged me for quite some time. I'm running Raspian Jessie on my Model B Computer, and Ethernet seems to be working because all three of the yellow and green lights are on and the two arrows are blue. But when I go onto Chromium and search something it's not available. The same goes for APT commands.
Thanks.
Update: Here are the results of ifconfig and cat /etc/network/interfaces/
