Fiber comes into apartment, goes to white ONT box on floor under television stand
DVR goes right into white ONT box
Phone goes right into white ONT box
Coax goes out of white ONT box > Actiontec router in other room (using existing coax cabling)
Actiontec > Ethernet into WAN port of TC
Wireless on Actiontec is OFF (i.e., Actiontec does not transmit wireless signal)
TC in bridge mode.
All devices connect to TC, backups work, etc. IP delivered by DHCP on Actiontec, passing through TC bridge.
Actiontec Firewall on default "medium" security; firewalls active on all Macs on network.
Everything seems to be working fine, and I'm currently getting 25mbps down and 20 mbps up off my MacBook laptop (which should be connecting via 802.11n to the TC)
