Question about Arris SURFboard SB4100 Modem
Had the modem connected for over a year without any issues and it suddenly stopped working. Modem is connected to wireless router. Ive already reset it, attempted to do a diagnostic on it, but nothing works. Config screen on modem shows 0.0.0.0 for HFC IP ADDRESS. Can't connect from XP machine, Vista or XBox.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

It is the MAC address that needs to be scrubbed from the modem.
power off the desktop, power off the modem, unplug the data cable from the modem, unplug the POWER connection to the modem.
WAIT 3 MINUTES
Connect power to modem, let it reset
Connect data cable to Modem
power on computer
Modem should now connect & work with desktop.
Each time you switch between systems, you may have to do this. More than enough to make me buy a router. =)
Please rate the post. =)

SOURCE: Wi-Fi isn't working
This could be a duplex issue. When you log into the belkin does is assign you an IP address? Have you used a ballpoint pen to reset the EMTA since you have connected the router?

When the SurfBoard modem is powered up and connects to the internet on the WAN interface, it automatically gets an IP address from your ISP. When another machine is powered up and is connected to the modem via a USB cable, it is automatically using the WAN IP address to communicate with the world. If it is connected via the Ethernet connection, the modem automatically issues it its own IP address for use on the internal network via DHCP. The modem's internal Ethernet connection is 192.168.0.1. The next machine powered on will normally get an IP address of 192.168.0.2.

the motorola modem that att is using uses 192.168.1.x subnet. log onto your router and change it to 192.168.b.x where b is any number between 2 and 254 (just not 1). You should also log onto the modem and change the setting that allows it to share the external ip address with the router. You will need to do this if you plan on accessing your network from the internet.

I have a similar problem. The common denominator seems to be the SB5101. I have a brand new Belkin Surf 300N, same issue. The modem will not give DHCP to the router. I can connect fine via ethernet to the modem directly.
This modem seems to be a dinosaur.
