New Fairpoint Westel DSL modem, model 6100. You can plug any computer directly into it and get on the internet(after rebooting the modem each time you change computers). However, you cannot just plug in a router. To use a router you need to go into the modems software and enable "bridge mode: FYI its not a case of needing to log onto your dsl account as any computer can get online directly, even computers with no added Fairpoint software. If computers are getting on using DHCP why wouldn't a router get online also using DHCP?
