I currently have tv only for U-Verse and internet through Cox (ATT can't compete pricewise or speedwise with what I have).
My current connections are:
coax > modem (192.168.100.1) cat5E > router (192.168.1.1) > wired to multiple computers many with static IP's based off MAC's, DNLA devices and numerous wireless devices
line into green DSL port on 3801HGV > coax homePNA for 1 tv and LAN to 2nd tv
I am wanting to combine the two routers into one network because I want to use the wired LAN ports of the 3801 for some new items (it's in a different part of the house).
I've read the suggestions when using a current setup behind the 3801 but those all seem to pertain to those who are also using ATT for their internet.
I understand I obviously need to assign different ranges of local IP's and was going to set the 3801 to use the optional 172.16.0.0 starting point and also turn off the wireless feature. I assume using the 172.16.x.x sticks after a power outage? This would present me with the least amount of hassle dealing with all the current assigned IP's and port forwarding instead of changing my router to say 192.168.2.x range.
But my questions are: do I have to hook my incoming internet up from the current modem to the 3801 (I guess the ONT port?) instead of the current router's WAN port and then plug my router's WAN into one of the LAN's on the 3801. Or can I run a cable from one of my current routers LAN ports to the 3801 to give anything on that side internet access? Or can this simply not be done? If I can run from my current router's LAN port do I run to the ONT or LAN on the 3801 and does it need a crossover or "standard" CAT5E?

Actually the purpose is also so it's no longer necessary to switch networks on various devices that have the Uverse app installed on them to act as remotes for the Uverse tv receivers.

Thanks for the reply SomeJoe7777.
If I were to disable dhcp on the existing router where I can set static ip's, would that change my options?

If you completely disabled DHCP on the existing router and statically assigned everything, then yes, you could bridge the networks together LAN-to-LAN and it would work.
You would also either need to:
1. Use the same subnet for everything and ensure that your static IPs that you use don't overlap the DHCP range on the 2Wire.
2. Use different subnets, and multihome either the computer(s) needing to contact both routers, or place a secondary IP address from the 2Wire subnet on your router so that it will route packets on the same (LAN) interface.
