With FTTP, the router does not need to support VLAN ID, so you can connect the Google router directly to the FTTP box. Configure PPPoE and your username and password. The Google router only has one LAN port so you could get a 5-port switch to connect computers,  etc, or, set the VX420 as an access point. If the VX has a specific setting for Access Point mode, you might be able to connect its WAN port to Google LAN port. Otherwise, disable its DHCP and give it a LAN ip address like 192.168.1.2, and connect a LAN port to Google LAN port. You can also disable VX wifi if you only want the Google wifi. Regarding the Arlo, is this a home CCTV setup. What model is it? Do the cameras stream to a recording unit on home network, or do you view them remotely? ... View more
