I was wrong about updating. LiveCD has the same problem. But i have confirmed that it's my router, after surfing about 2 hours on PPPoE directly, which is perfectly okay.
I don't know why my router would be the problem, and don't know how to fix it either. I've tried to disable ipv6 in FF and Ubuntu, set the MTU from auto to a correct value, both don't work for me. Hope someone will finally come up with a solution. Regards -- The connection to the server was reset while the page was loading.
