Hi,
   My old modem from Roadrunner (Time Warner) died and the service man replaced it with a Arris TG852 modem/router. then my problems began. I would like to have the Arris modem act like a modem and not a router. The network governed by the DIR works fine but none of the clients can connect to the internet.

Below are the steps I have tried.

in both steps below, The DIR is connected to the Arris using the Ethernet not the Wan port.
 1. I tried disabling DHCP on the Arris router and setting a static IP address for the DIR router. This worked for a bit and then quit. Some of the computers said there were duplicate IP addresses on the network. If fact the same IP address showed up in the DNS list of the Arris and the DIR routers.. even though the Arris router had DNS disabled.

2. After reading other forums. I enabled DHCP on the Arris and set it to passout IP address between 192.168.0.2 and 192.168.0.99. I then setup the DOR to pass out addresses between 192.168.0.100 and 192.168.0.200. then moved the DIR into the DMZ of the Arris. Still no access to the internet.

If anyone might be able to give me some help it would be GREATLY appreciated! 
Thanks.
Jim

What ISP Modem do you have? Stand Alone or built in router?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
Double NAT
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

Some things to try: - Log into the routers web page at 192.168.0.1.
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Try turning OFF SPI.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.


Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

Try Mac Cloning on the 655 to the Arris modem
Arris Modems and External Routers
