I have spent a VERY long time fighting with the RP614. I have checked just about every possible configuration option very carefully and very thoroughly and I cannot make it work, either with a cable modem or a set-top box. This morning I spent two hours on the phone with an incredibly helpful and patient support technician at Netgear, and we went through all the tests again. He was stumped too.

The problem is that when its starts up, the RP614 fails to establish the WAN IP from the cable modem - I don't know why or how; the WAN light always glows orange (=failed link) and the IP address always shows 0.

I CAN make the RP614 work by transferring the cable from a connection which is already working - set the WAN IP in the RP614 as fixed, copy in the IP details of the working link, set the MAC address to be the same as the working router, then switch the cable. This works until you turn off the cable modem or it renews its IP address (every four days or so). Of course, it depends on you having another working router, which kind of defeats the point of the exercise, but it does demonstrate that it's not a problem with either device, just something to do with the way they (don't) communicate.

I have seen an identical problem with a PC, where the cable modem refused to recognise the network interface on the motherboard, but did recognise the USB network adapter supplied by NTL.

Sorry I can't offer a solution, but at least I can confirm that the problem is (very) genuine.
