Dec 28, 2012 · I've tried both Box 4 and 5 of the routers and there seems to be a problem with both upnp and port forwarding working which has stopped several games of mine from working. I was told a firmware was rolled out but not given a time. I tested with a Netgear router I had and all ports and upnp seem to be working fine - it's just the O2 routers. The Netgear C7000 has the following ports available on the back of the modem. Power - Connect the supplied power cord to this port. Ethernet - Provides internet access to a single device. Only one port is active at a time. Note: This is a LAN Gigabit Ethernet port.
Re: Using C7000v2 as modem only for a separate router Yes, check the user manual for router or NAT mode. There should be a modem web page feature to set the modem from router to modem only. May just have a check box that says router mode or bridge mode.
