From the TWC forum I like this passage:
"Log into the modem,Go to LAN setup and under Nat section select Bridged. that will grey out all the DHCP
then the Firewall tab and unselect “enabled”
then turn off wireless, save changes, reset it
If any of the above is greyed out call twc"
To reset it, we have to power cycle this one. Now I can plug in my new router from the Arris to the WAN/Internet port of the router and follow the router instructions from there.
I don't see the router model but many require a firmware update before they are stable.

I'm currently with Time Warner Cable, and have their basic Internet plan; which they supply with a standard Router/Modem in one box: Arris TG862G. It's pretty sluggish at times, and can be frustrating to play any games online with it's inconsistencies. My goal was to purchase a heavy-duty router and just use the Router/Modem as a bridge. I purchased a used, almost new, Netgear AC3200 Nighthawk X6 R8000 Router that is a tri-band.
I know how to physically hook-up the hardware, and have successfully done with before many years ago. However the issue isn't with the physical connection of the pieces, but what I suspect to be a problem with the two devices communicating with each other. My Ethernet port on my computer that I'm using to configure the Router doesn't seem to be working properly, but it's not a huge issue since you can configure it wirelessly, as long as you're connected to the Netgear Router.
I have my Router/Modem's WiFi disabled, and have it Bridged under NAT, so the wireless signals don't interfere with one another. The Netgear Router has all the LED lights lit up "properly" according to all the things it needs to operate normally. However I use the word properly with quotations, because nothing is further from the truth.
It was a struggle just to get these two devices to successfully talk to one another, and I finally seem to have done so, but the issue now is that it's inconsistent. So much so that I get frequent drops in internet access (Limited or no internet access) and every so often the Router just "reboots" from my computer side, but the LEDs on the Router during these windows remain unchanged, and working "properly".
It's not just my computer that's having this issue though, because my phone will lose the signal at the same times the computer hiccups.
I'd love to give anyone more information on this topic if needed because I've been working at this for 2 days now, and I think it's time to let outside, and expert, perspectives into this.
A list of my computer specs if they're at all relevant:
OS: Windows 7 Home Premium
Processor: Intel Core i5-2030 CPU @ 3.00 GHz 64-bit
I have reinstalled a new hard drive and OS from original build; I only bring this up because I've seen experts ask the same question to other people with similar issues.
Here are two images that may help: top image is ipconfig with connection to the new router, and the bottom image is a map of the network.
Any and all help will be greatly appreciated.
