You told us that you had a Ubee modem/router, so the Ubee is already performing DHCP and NAT routing functions for the network.
You don't want another router....the Belkin.....also doing DHCP and NAT, since you will have IP address conflicts and a Double NAT error on the network in this case. So, DHCP and NAT needs to be turned off on the Belkin. That would be bridge mode on the Belkin.
IF.....the Ubee can be re-configured to operate only as a simple modem......(and that is a big IF with many modem/routers)......then you could run the Belkin as the network router. There is really no advantage to doing this, unless you feel that the Belkin can hand out IP addresses and handle NAT duties better than the Ubee.
Your network devices will not care whether they get IP addresses from the Ubee or the Belkin.
It sounds like the advice on the Netgear website was biased toward setting up the Netgear as the router, which would be expected, just as Apple would advise if you were asking about an Apple router.. If you get on the Ubee site, you may see different advice. 😉
