Thanks, let me re-phrase the question then. How do I do it, re. what am I doing wrong. Please help me understand - I am a network newbie.
Initially I followed the instruction here: (http://www.dslreports.com/forum/r31057540-Networking-HOW-TO-Bridge-G1100-So-your-Router-becomes-Primary ) *Moderator edited: Take care with URLs as they don't work if you add characters to them.
1. Using a Computer/Laptop that is hardwired to the router (Connected via Ethernet)
Logon to your G1100 - (»myfiosgateway.com or »192.168.1.1)
2. Go to 'Wireless' Under 'Basic Wireless Settings' turn off both 2.4 GHz & 5 Ghz.
Click 'Apply' at the bottom of the page.
3. Under 'Advanced Wireless Settings' click on 2.4 GHz SSID Broadcast and Turn that off
then click 5.0 GHz SSID Broadcast and turn that off as well.
4. Now that the wireless access is shut off, Click on 'Firewall' at the prompt click 'Yes'
Now under General for IPv4 Settings & IPv6 Settings set BOTH to 'Minimum Security'
and click Apply at the bottom.
5. Next click 'My Network' now Click 'Network Connections' now click 'Advanced >>'
Now click '5.0GHz Wireless Access Point 1' and then click Disable, once that's finished
hit Apply
6. Once you're back at Network Connections click 'Advanced >>' and click 2.4GHz Wireless
Access Point 1 then Disable that as well, and hit Apply.
7. Once both Wireless APs are Disabled, Click 'Broadband Connection (Ethernet/Coax)'
Then hit 'Settings' at the bottom, Uncheck the box beside 'Internet Connection Firewall'
Then beside 'Internet Protocol' change it from
'Obtain IP Address Automatically' to 'No IP Address'
(Once You hit apply you will no longer be connected to the internet.)
(NOTE: If you want to chose your DNS Server, change DNS Server from Obtain DNS
Server Address Automatically to No DNS Server)
8. Now click 'Release' and then quickly click Apply, then click Apply once again.
9. Now Click on 'Network (Home/Office)' and then hit Settings.
Once in the Settings, under General change the IP Address from "192.168.1.1" to
"192.168.1.2" This way there's no conflicts from both routers trying to use same IP...
Now under the Bridge section; Check the box beside 'Broadband Connection
Ethernet/Coax)' and uncheck the boxes by both Wireless APs.
then change 'IP Address Distribution' from DHCP Server to Disabled.
10. !!!WARNING!!! Once you click apply, the G1100 will be put into Bridged Mode and will
no longer assign IP addresses, So don't worry if everything stops working once you
apply the settings.
11. Hit Apply and then take an Ethernet Cable and plug one end into any of the 4 Ports
on the G1100 except the WAN Port, then plug the other end into the WAN/Internet
Port of your new Primary Router.
12. Next plug your PC into your new router and reboot both routers.
Once they have rebooted, logon to your new router and make sure it's IP Address
range is 192.168.1.0... If it isn't Refer to your new Routers manual on changing it.
13. Now check and see if Verizon assigned your new router your Public IP Address (You
might need to click Renew in your new routers settings) If it has assigned an IP to
your new Router, you are good to go. Your new Router is now the Primary and your
G1100 is just a bridge from Coax (MoCa) to Ethernet.
If you have Verizon TV as well, You'll need to take another Ethernet Cable and run it
from one of the Ports on the new Router to one of the 3 Remaining ports on the
G1100, that way your new Router will assign IPs to your STBs and they can access
the net.
But I could not get the WiFi router working - it indicated connectivity, but nothing could load. Had to do a 30-30-30 reset. At this point I am basically only running point 2&3.
What is the crucial part and where do I need to educate myself to fix it? And is this a WAP setup?
Again - the FiOS is a gateway that somehow needs to be connected to the cable box for menu and stuff... 
Thanks
