2 VoIP providers and 2 routers

I have 2 VoIP phone lines from 2 different VoIP providers. So I have two phone devices: a wired Vonage RT300P2 and a Wi-Fi Babytel WRT54GP2.

I need those two phone lines from different providers. And I need a Wi-Fi router to access internet from the living room.

My current working set up is: Modem -> to WAN wired Vonage -> to WAN wifi babytel. 2 phone lines work fine. But I can't use wifi network. When I slightly change this set up "Modem -> Wan wired Vonage -> to LAN (instead of WAN) wifi babytel, I loose my babytel phone line.

I tried another set up, placing Wifi first and wired second: Modem -> WAN wi-fi babytel -> to Wan wired vonage. My wifi network works fine, but my Vonage line is out. Same when I connect to Lan wired Vonage iinstead of Wan. So it seems I can't put my WRT54GP2 first and get the RT300p2 phone line working.

Any (simple) ideas on how to get my two phone lines and my wi-fi network working?

They are on different gateways. The Vonage adapter default is 192.168.15.1 and I have no idea about the other since I've never used it, but you should be able to change the IP to 192.168.15.2 and it should work fine. I have my Linksys wireless router set-up this way and have no problems. Doing it this way, you can still browse your network (regardless of which one it's connected to) and get into both routers.

If these are all routers - and it seems that they are - then you would be better off changing the subnet numbers rather than putting in an IP address. If the IP range for more than one device is the same, then the routers will get pretty confused over what's what.

Most Linksys devices come with a default of 192.168.1.X, with 192.168.1.1 as the admin port. Netgear prefers 192.168.0.1.

If you make one of your routers start at 192.168.1.1, another at 192.168.2.1, and the third at 192.168.3.1 (or any other number you pick that is different between the routers), then they should work for you.

These are 2 Linksys routers.
First router gets its IP (WAN) from Cable Modem and its LAN address is 192.168.15.1
Second router gets its IP (WAN) from first router and its LAN address is 192.168.15.2

When RT300P2 is first and WRT54GP2 is second, both Vonage (on first router) and Babytel (second router) phone lines work. Smile

But I can't use my Wi-Fi router (the second) to access Internet. Sad

When I change this set up and place the WRT54GP2 first and RT300P2 second, I can use my Wi-Fi router to access Internet. Smile

But my Vonage phone (second router) is off. Sad

I will be happy Very Happy

when I will be able to acces Internet from my Wi-Fi router (WRT...) AND my two phone lines works.

sorry for my english. It is not my first language

Did you try putting in a static IP address for your laptop. I had to do mine that way, Just set the laptop to 192.168.15.102 (or whatever last 3 digits) and put in the Default Gateway as 192.168.15.1 - don't forget the DNS numbers as well.

Mine is set up with the RTP300 first at 192.168.15.1 and then the wireless router as 192.168.15.2 . I'm still able to browse my network from any computer to any computer and can still access the admin pages for both routers.

Each level has a separate scheme for Internet addresses. I think you have a simple routing issue.

Internet -> (WAN) Router1 (LAN) -> (WAN) Router2 (LAN)

Internet -> (WAN) Router1 is obviously working.

Router1 (LAN) is set up with IP address range of 192.168.15.x.

Your problem, I think, is with the LAN on router 2. You need to set that up so that the LAN ports are issued IP addresses in a different subnet. 192.168.16.x would work fine. To do this, you want to change settings in the LAN (NOT Internet) section of the basic setup screen.

LOCAL IP Address: 192.168.16.x
Subnet Mask: 255.255.255.0

This will make the second router issue 192.168.16.x addresses to all of its clients.

The Internet settings on the second router should be left at "Obtain IP Address Automatically", as it will get an address (in the 192.168.15.x range) from the first router.
