Configuring modem/router to modem only

I believe Cox removed the bridge function from most gateways.If they haven't removed the feature, go to 192.168.0.1 and ADVANCED > Administration > Router Mode > NO or see page 11-12 of manual for more details. If this doesn't work, then it has been disabled via the firmware. I personally don't think its right for Cox to modify customer equipment without their permission or consent but they see it as simplifying the product to improve "customer service". I counter this by saying their networking customer service is horrible at best, and non existent at most. I know because I used to run it in it's infancy. 

In general, I suggest you either buy/trade the gateway for a stand alone modem, or put the Dlink router into AP mode. But then you need to run a ethernet wire from the gateway to where the Dlink router will be. Putting them side by side won't increase your signal, if anything, it will mess it up. That means it will give you better wireless coverage, but you won't be able to use any of the features of the Dlink router.

BTW, I don't see any router by the model number DIR-837. Sure you don't mean DIR-835?

Thanks Tecknowhelp. I meant to type DIR-827, my apologies. Regarding the gateway functionality, I personally own the Netgear gateway and it is not Cox equipment so I have the ability to change the Router Mode to NO. However, my problem was that as soon as I did that my internet was lost and I was unable to get my Dlink router set up without an internet connection (hard wiring to the gateway did not help). 

I have already run ethernet from my basement where the gateway is located to my upstairs where I'd like to place the new router so there is the possibility to put the router in AP mode (if I can figure that setting out). 

I guess ultimately is there something I need to do, either myself or by calling Cox to ensure I don't lose internet connectivity when I switch off the Router Mode? 

I'll be honest, I'm an engineer but in no way a networking/computer expert so any more information you can provide is greatly appreciated!

After setting the gateway to bridge, you need to power down the router, reboot the gateway, then when it's back up, turn on the router. This is because when you turn off router(NAT) your turning it into a bridge between your Dlink router and Cox. Requires a reboot for the Dlink router to get a IP via DHCP just like if you connected it to a normal modem.

If gateway is in bridged mode, the router has to be in router mode. If gateway is in router mode, router has to be in AP mode. You could keep both in router mode, but then you have to set up port forwarding and triggering and different subnets...its a mess, and not performance optimal. The only plus is it would give you Wifi in both locations.

Cox is hit or miss. They should be able to see the IP, MAC address and vendor of the equipment assigned the public IP by Cox. Some CSR's don't know how to see it through. If you find one who does, if they see a Netgear CPE vendor, then it's not bridged, if they see a Dlink vendor, even if a invalid IP, then you atleast know it's bridged. The firmware loaded onto the gateway is Cox's, even if the hardware is yours. So even if the option is there to disable router mode, it helps to confirm it actually works.

PS. I assume you don't want Wifi in the basement right? Turning router mode turns off Wifi on the gateway too. They are also both Wifi N600 devices with internal antenna, so I would be curious what gives better performance. 

PPS. Fun fact, I actually beta tested the DIR-827 through Dlink's forum. If you need help, ask for Furry.
