RT31P2 phone adapter with WRT54GP2 wireless Internet Q's

Posts: 15 · Vonage Forum Associate Joined: Dec 30, 2005 Posts: 15

Hello,

I have a Linksys RT31P2 that is currently set up with the Vonage service. We have two phones that work perfectly fine. The cable Internet, with Adelphia as the ISP, comes in through a Scientific Atlanta DPX110 cable modem into the Internet jack of the RT31P2. A Dell PC is connected to the RT31P2 through the Ethernet LAN. The PC can connect to the Internet perfectly fine, and, as I said, the Voip phones also work perfectly fine.

Now we have another computer with a D-Link wireless network adapter. We bought a Linksys WRT54GP2 router in order to provide wireless Internet access to this computer. I have the RT31P2 connected to the WRT54GP2 with a LAN --> LAN connection (I also tried LAN --> Internet).

My question is this: how should I configure this network?

Any help is much appreciated.

Did the configurations that you tried work? They should have, except that with the RT31 LAN connected the WRT LAN, you should turn the WRT DHCP function off. With the RT31 LAN to the WRT WAN (internet), you should leave the WRT DHCP working.

The difference is, with the LAN-LAN connection, the WRT is working as a bridge, and computers plugged into either router will be able to communicate with one another. With the LAN-WAN connection, computers serviced by the WRT will be on a different subnet and will not be seen by computers plugged into the RT31.

I don't think that I quite follow you...

No, the default config did not work.

Thanks.

OK, I gather that this is the same situation that you were talking about in another thread, but that you've decided on the option of keeping the RT31 and simply adding the WRT. Is this correct? I also assume that the RT31 is plugged into your cable modem. You said that your phones and the computer plugged into the RT31 are working fine. Is this also correct?

First, check the setup on the RT31. Is it set to act as a DHCP server? If it is, you should be able to use the factory default settings on the WRT and connect the WRT internet (WAN) port to one of the RT31 LAN ports. Power things up in this order- modem, RT31, WRT, computers. Do you still have good phone service and internet service with the computer plugged into the RT31? Do you now have internet service with the wireless computer? Get back to us and we'll go on from there.

Done.

No. The wireless computer can see the SSID (in "View Available Wireless Networks"). After initial connection, ipconfig displays an IP address of 0.0.0.0. Ipconfig/renew returns the message "unable to connect to the DHCP server." Attempting to repair the connection through XP (right-click and then "Repair") returns the message that the IP address cannot be renewed (the same as the command prompt, essentially).

Strangely enough, after a few minutes, ipconfig returns an IP address of 169.254.x.x, a range that belongs to the Internet Assigned Numbers Authority, according to an IP Whois search. I'm not sure what that means.

Thanks agian for your help.

Bump?

It looks like I missed your last post for awhile. With the setup that we've been working on (modem->RT31->WRT), can you unplug your wired computer (the Dell) from the RT31 and plug it into a LAN port on the WRT? Do you get internet service with the Dell when you do that?

Yarg.

Let's go back to the beginning. The WRT is new, right? Has it ever given you internet service, in any configuration that you've tried? In short, do we know that it works? Have you tried a factory default reset?

Here's the strange part. I cannot connect to the Internet, even if I just plug the modem directly into the PC. I know that it has nothing to do with needing to register a Mac address with my ISP (Adelphia does not require that). My PC, for some reason or another, needs to be connected to the RT3 (which is in turn connected to the modem) in order to connect. The TCP/IP settings for the network card haven't been touched.
