2 Modems

[pjmorgan.livejournal.com]

Is there an internet service provider serving Somerville that will allow me to have 2 cable modems without charging extra (or at a nominal extra charge)?    I prefer to plug directly into the cable modem rather than rely on the slower and less reliable wireless signal.  I believe Comcast wanted 25/month or something.  I don't understand why I can have a TV in every room that plugs into cable but not internet in every room

I guess I could try to fish cat ethernet wires, but I've found that to be difficult if your walls aren't already open.

Why do you need 2 cable modems?

I think you just need a router...

OP is saying that the coax is already run through the house, so why run cat 5 ethernet everywhere to use a wired router.

From my point of view, the cable modem uplink is so much slower either Cat 5 or wifi that I don't see the point of favoring either of them over the other. The exception would be internal LAN connections, but I don't think multiple modems fixes that.

To answer the OP's question, the answer is that every new cable modem needs its own real IP address, and IP addresses are a scarce resource. This is why NAT boxes were invented!
