Ubuntu recognizes that my ethernet cable is there and it says that a connection has been established except FireFox won’t work. I don’t know what to do? I was reading some woman’s post in the support community that was having the same problem. And the guy told her to go to terminal and type in “ifconfig” which I did and then he told her to post what it said. But obviously I cannot connect to the internet from that computer. I am using my other one. If anyone can help please do.
