This document describes how to configure a Verizon FiOS G1100 to act in bridge mode. This mode deactivates some cable television features, but it allows another router to obtain an IP address directly from Verizon. Other users have documented these steps in publications such as DSL Reports.
Login to the G1100 from a computer which is directly connected to one of the G1100’s LAN ports.
Select Wireless Settings→Basic Security Settings, and turn off 2.4 Ghz and 5 GHz wireless. Click Apply.
Select Wireless Settings→Advanced Security Settings, and disable 2.4 GHz and 5 GHz SSID broadcasting.
Select Firewall, and set Minimum Security for both IPv4 and IPv6. Click Apply.
Select My Network→Network Connections→ Advanced. Disable the listed access points, and click Apply.
Note the listed broadband connection. Select it, along with Settings, and uncheck Internet Connection Firewall. Set Internet Protocol to No IP Address. Click Apply. At this point, you will loose you connection to the Internet through the G1100.
Click Release and then Apply.
Select My Network→Network Connections→Network (Home/Office). Change the G1100’s IP address to 192.168.1.2 so as not to conflict with the replacement router. Under the bridge section, check Broadband Connection (Ethernet/Coax) and uncheck both wireless APs. Change IP Address Distribution to Disabled.
Click Apply. The G1100 is now in bridge mode, so it will no longer obtain an IP address. Connect your replacement router to one of the G1100’s LAN ports. From this point forward, you can interact with the G1100 by connecting a computer to its WAN port and manually assigning the computer an IP address on the 192.168.1.0/24 network.
