I have a dual boot setup with Windows 7 and Ubuntu 12.04. In Windows my connection is perfect but when booting into Ubuntu I cannot connect at all.
The network manager states that I'm connected but I cannot access any websites or ping any external addresses.
I've only been using Ubuntu for a few weeks so don't know too much about it yet. I'm also not well versed in networking.
The strange thing is that it has worked perfectly for a while after the initial install and sometime afterwards it was not working for about 2 days and then it worked again for a day and now it's completely non-functioning.
I'm investigating the possibility of it being an issue with recently install software but am hoping you guys can spot something suspicious with the results posted below.
Below is some commands and their output that I've run that I've seen asked for on other threads:

Thank you in advance :)
192.168.1.254
? Because from your outputs, it's supposed to be10.0.0.2
, unless you have a larger network setup with more than one router. What's the output ofping -c4 4.2.2.2
andgrep proxy /etc/environment
?10.0.0.2
anyway but was unable to connect. Also, I've added the output from your suggested command to the end of my question.10.0.0.102
IP address, with proper DNS and gateway settings? What's even weirder is that10.0.0.2
is actually up. I'll post an answer to change these settings.
