My ebayed modem arrived last night. I immediately googled to find out what I should do with it and found out it can be hacked to think its a 5660. That will provite NAT translation and routingas well as DHCP and DNS services. Now I question whether I need to do this. I have a wireless router for DHCP. All I need is the connection.
If the connection works well without modifications, I probably will refrain from the hack. However, now that my ICS is up and running and I plan to switch to ComCast soon enough (BellSouth just costs too much after all their hidden charges)
