Check PDFs To my initial dismay, I found that the VDSL modem could not function without the AT&T 2Wire Router. This was a problem for notesme as the 2Wire Router is limited in functionality and I was used to administering my home network using a [https://en.wikipedia.org/wiki/Linksys_WRT54G_series#WRT54G Linksys WRT54G] with [http://www.dd-wrt.com DD-WRT] firmware installed. I used this firmware load to allow me to assign [https://en.wikipedia.org/wiki/IP_address#Uses_of_static_addressing static IPs], [https://en.wikipedia.org/wiki/MAC_filtering MAC Address Filtering], and reasonably complex [https://en.wikipedia.org/wiki/Port_forwarding Port Forwarding].

U-verse setup*Settings-LAN-DHCP = Configure Manually*Settings-LAN-IP Address Allocation for router = DisableI did a little bit of Googling & some experimenting and ended up with a solution I was happy with. Essentially I disabled the wireless radio on the 2Wire i38HG, Public, Router WAN*Settings-Firewall-Applications, Pinholes plugged my Linksys WRT54G into the i38HG and had the i38HG pass all traffic through to the WRT54G. I have the local address of the i38HG as 192.168.0.1 and it can assign 192.168.0.2 through 192.168.0.5 on its wired ports. The WRT54G has a local address of 192.168.1.1 and DMZ = DMZplus mode for Router*Settings-LAN-Wireless = Disable Wireless Access Pointassigns all wired & wireless ip from the 192.168.1.XXX block.

The trick to getting all to work is to ensure the settings are correct on both the i38HG & WRT54G. Below is a explanation of the steps to go through to set your network up like mine. I'm assuming you've already got DD-WRT installed and working on your Router . If not, visit the [http://www.dd-wrt.com DD-WRT website] for help. The IP address of your AT&T 2Wire i38HG Router is printed on the side of the Router. The default password is a long string of numbers printed on the side of the DC Power Supply / Battery Backup.
