Netgear CM1200, No IP address gaming console or router
Please help, I purchased the Netgear CM1200 to hard wire my computer, PS4 and smart TV, set Up is successful through desktop and IP address is acquired at desktop, but when connecting a smart tv, gami...

Actually on second thought I’ll just keep it since realistically everything else has an intel chipset except the 1000-1200 series which have the broadcom. I was using a CM700 and R7000P but started seeing signal issues on the CM700 and experiencing channel hopping and eventually spectrum said to fox the upstream i had to add a splitter... But with the more powerful 1200 modem my db and svr downstream are -9 and 36-41 respectively with my upstream channels all reading above the acceptable thresholds. Worth the investment to not need a splitter.

Yes, the 1000 thru 1200 model series are worth keeping since they are Broadcom based. I presume you do know about the Intel base modems and there known issues then.
Yes be sure there are no line splitters inbetween the ISP service box and modem. You'll be fine there. Just connect up a router to Port #1 and you'll be good. If you connect a router that supports Link Aggregation on is't WAN side, then you can enable LAG on the modem as awell then use Ports #1 and #2 for that.
Enjoy. :smileywink:

I also just bought the CM1200 not realizing that I could not use
2 routers ( Nighthawk R7000 & Asus Cellspot ) on this Modem
connected to 2 different ports.(Unfogivable not to mention that upfront, btw)
I do have an 8-Port Gigabit Switch ( I beleive and unmanaged one ),
would that work? Or a hub?
Both routers hooked up to the Switch/Hub to ethernet connection 1?
Thanks.

I should also mention that I do not
want to set up either router as a repeater.
One router is in the basement, the other
upstairs both set up seperately.
Thanks

Along the same line, advertising for most automobile models fails to
mention that there's only one driver's seat, steering wheel, instrument
panel, and so on.Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual. Look for "LAN ports".Is this a new installation/configuration, or was this stuff
previously working in some way with some other modem, or what?> I do have an 8-Port Gigabit Switch ( I beleive and unmanaged one ),
> would that work? Or a hub?"work" as what? Connected how? Connecting it to a LAN port on the
CM1200 would be a mistake.> Both routers hooked up to the Switch/Hub to ethernet connection 1?
If that means what I think it might mean, then no.General advice: An Ethernet cable has two ends, so specify where both
go. Also, if a device has different types of Ethernet ports, then
"connected to device" is not enough detail.> [...] I do not want to set up either router as a repeater. [...]
What, exactly, does "as a repeater" mean to you?
Almost certainly, your (unspecified) ISP is providing you with one
external/public IP address, so, if you want to connect multiple devices
to the Internet, then the only thing which you should connect to your
modem would be a (one) NAT router; all your other devices should be
connected to the LAN ports of that router. (Those ports are really
parts of a small network switch, hidden inside the router). You _can_
connect a (another) network switch to any of those LAN ports.
> One router is in the basement, the other upstairs both set up
> seperately.What, exactly, does "set up seperately" mean to you? Both configured
as full-function routers? Which one is where? Where's the modem?What's the purpose of the second router? If it's to extend your
wireless-network coverage, then you might get more satisfactory results
if you configured the further-from-modem router as a wireless access
point, instead of as a full-function router. Look in the R7000 User
Manual for "Use the Router as a Wireless Access Point". (Details might
differ if you want to use the R7000 as your main (only) router, but the
picture in the R7000 manual is good.)
Also, starting your own thread for your own problem is usually more
helpful than extending some months-old thread with different details.
You can always include links to any old threads which you think might
be useful. - WOLFY1959Dec 01, 2019Aspirant

Most people may not be tech-savy enough to know, that when theinfo for this item says "4 Gigabit Ethernet Ports to connect more
wired devices" That because it doesn't have a built in router that
the said ports can only be used under certain circumstances.
But hey, I appreciate the sarcasm.
