i thought about it being a bad ethernet cable, i'm going to take an extra home from work when i get off in a few hours and try it, and yeah, the one being used is the same one i've used for ages
"i'm assuming that u tryed it with the NIC interface of the modem connected to a NIC in yr machine ", yep

, doesn't work
i hope it' s not a dying nic, the one i'm using right now is integrated into my motherboard, which is about 3 months old, lol, it's an msi board with an nforce2 chipset, so an nvidia nic... maybe i should try my PCI SMC nic tonight and see what happens?
