I have LMCE running as DHCP and I changed the numbers that it assigns to match what the WPG54GS uses (default is 192.168.1.1).
That is very wrong for several reasons, do yourself a really big favor and leave it at 192.168.80.X as it was.
Thom... you are starting to sound like the Vonage Tech support
They said the same thing about trying to change the IP for the Vonage VOiP Router. Anyways, I think I am in the same boat as I was last night. I installed the i386 version of LMCE instead of the AMD 64 version. I also kept the default settings for the network as they asked during the install. I also left the DCHP enabled on the wireless router. So now, my configuration looks like this:
Cable Modem --> Vonage VOiP Router, 192.168.15.1 --> eth0 (Core/Hybrid) 192.168.80.1 --> Eth1 192.168.80.103 --> WPG54GS Router (DHCP enabled) 192.168.80.2 --> Wireless Laptops (192,168.80.1XX).
Now I have internet access on both laptops like I am suppose to and my Vonage phone works. I am still getting "No data available" when I type ethtool eth1. Should I be worried about this?
