    Hi,

    I recently got a new router and need a diagram or picture to connect it to the following: VOIP phone adapter, modem, computer. Or however I connect all of this stuff to get the router to work without losing Internet (high speed cable) or phone usage.:confused:

    Thanks.:)

    I suggest you start with make/model of the modem, router, VoIP adapter. You can either just connect the VoIP adapter to a LAN port on the router, or connect the VoIP adapter between the modem and the router's WAN port. The second way is sometimes better for VoIP, but you may have to do some configuration of the VoIP adapter to allow port forwarding for such things as games and voice/video messenger applications.

    BTW, I'm moving this to networking.

    Trendnet TEW 432BRP router. RCA Comcast modem, DCM425C. Motorola adapter, VT 1005V. I wonder if I should just set up and configure the router, then add the adapter.:confused:

    Thanks.

    I have that same VoIP adapter, I've had it connected both ways, in front of the router, and after the router. I now have a router with QoS, so I have it connected to a LAN port on the router, works fine.

    It'll be easier to configure the modem and router, then add the VoIP adapter as a client on the router. OTOH, if you experience voice quality issues, you may want to connect it between the modem and the router, and then look into putting the router into the DMZ of the VoIP adapter so you can forward ports.

    I have mine set up as:

    DSL Modem -----> VOIP router ------> Wifi Router
    then all my PC's connect to the wifi router.

    That's the setup for the best voice quality, but if you forward ports, you need to either punch holes in the NAT layer in the VoIP adapter, or put the router in the DMZ of the VoIP adapter.

    John, I'm getting confused by the terms. DMZ sounds like something from the Vietnam War. NAT is probably something I won't get involved with but I'm curious.

    I have another thought. All I really want to do is connect my laptop to my PC which is ten feet away. The complicator is the VOIP adapter. Or not?:confused:

    Does an ethernet switch work like a USB hub? What about a coupler, or is that just for extension? I may already have the right cable, but can you tell me the specs needed?

    Thanks for your help with this.:)

    NAT = Network Address Translation - for example, you have 1 public IP address (assigned by your ISP), and more than 1 computer hooked up to a router/switch/etc... The router will in turn assign any computer that is connected to it it's own "private" IP address (usually 192.168.x.x, or 10.x.x.x) Your computer (say it's 192.168.0.100) goes on the internet, but the internet sees your IP address as the one from your ISP (say 100.10.45.32).

    DMZ = Demilitarized Zone (just like in Korea...) - this basically puts a PC or server that normally sits behind a firewall "out in the public", meaning the firewall does not protect that PC/Server the same way it protects the other pc's/servers.

    I'm sure someone can explain these terms better than I can, but that's the definitions I was given when I learned.... Hope it helps!

    Yes, an Ethernet switch is very similar in concept to a USB hub, just for networking. Try the simple connection scheme, and if the VoIP isn't an issue, use it that way. If you have voice quality issues, we'll have to get a bit fancier. :)

    Know what? I went back to my old router and everything is fine again. I was told that some brands/models just don't work with the VOIP adapters.

    Thanks again for the help.
