I am having a problem with a very slow internet connection on my Ubuntu laptop when connecting from home. Browsing speeds are extremely slow, and the problem is seen with both Firefox and Chrome. (Firefox sometimes times out trying to load the Google home page.) If the same computer is logged into the domain at work, it is quite fast. I can connect to work via VPN at home, but this does not speed things up at all. Other computers connect to the same network at home are not slow.
I have tried disabling IPV6, but this did not help. It does not seem to be a DNS problem because if I type an ip address directly into the browser, it is still slow.
One curious thing is that if I pull up the Network Connections dialog, it says that Auto eth0 has never been used, even though that is what I thought I was using to connect.
