Typically your modem is a router giving DHCP information to the network machines. In this case a firewall does NOTHING positive for you: The modem forwards NOTHING to your machine, so no firewall is indicated. Ubuntu has no built in firewall, others need to have it turned off. You need to have DHCP enabled or else you must know all the network details: modem IP, DNS servers, your own IP etc. Likewise a firewall on your windows machine is valueless. Typically your firewall must allow ESTABLISHED,RELATED back but eg guarddog for ubuntu does not. Who knows what your firewall is doing. Don't use it. (The modem/router allows nothing from out to in and allows all inside stuff back [and it gets very complicated]) Now you can start: can you ping your modem? can you ping when you can't connect to internet?
