ambit 250 and 255 cannot connect to internet

[Y4551n]

hi guys, im having some trouble connecting online.

i have 2 modems that have went down this week and i cant seem to get back online.

i got a motarola sb5101e at home which works fine but the other 2 modems i cant seem to get online. there not mine but a famiy members.

they have the latest revison of haxorware on them. The modem status says its operational but when i try surfng the net nothing works. i have tried countless macs and even macs that i know are working.

i even changed the nic mac but still nothing. tried all different frequencies for telewest and still nothing.

even tried the tftp ip servers addresses and config files and still nothing.

any ideas guys?

like i said i got another one which works fine in the same house.
