Whats the difference between wireless routers with modem and without modem?

Your post is a welcome reminder that oversimplification at Levels 2 (Data Link) and 4 (Transport) inevitably result in errors at the Application level.

Just make note that TCP/IP do not follow OSI layered model.

I also believed this for a long time, ISDN is digital though. Thats why ISDN modems were called terminators or something like that. Can't flipping remember now


Also you said a router joins two networks... thats a bridge. A router is an intelligent hub (switch) that can do its own routing... assign IP's and provide DNS.

ISDN - It's an NTU Network Termination Unit
