problems when connecting directly to the modem.. hmmmm... have you reset the modem? if so, call your cable company. it's their job to provide a service. even if they didn't supply the modem, they are still required to provide tech support. if they don't, ask to speak with someone who can. i wound up speaking with a network engineer for adelphia after their tech support was unhelpful and that guy was awesome. network engineers usually don't have much to do.
