Disable modem on C7000v2 modem/router

Question

Hello,My cable company is making me to use their modem and I need to either rent a router from them or purchase my own. I’m currently using a Nighthawk C7000v2 and was hoping to just use it as a router instead of a modem and router duo. (impacted by covid and trying to save some money)Is there anyway to disable the modem on my C7000v2 to use it only as a router? My cable company told me it’s possible to but I’m way out of my league here and can’t seem to find a clear answer. Can anyone provide some insight on this?Thanks

The C series modem can only work in Gateway router or modem only modes...

&gt; My cable company [...]Who/what is that?—&gt; sorry, I should’ve said my internet provider- spectrum&gt; [...] is making me to use their modem [...]Why?&gt;&gt; they advised that my modem is using DOCSIS 3.0 which they are no longer supporting and need to use a modem with 3.1 or above. Technically I’m not forced to use their modem but I’ll need to spend less money if I only need to buy just a router.——-I took your advised and called spectrum who told me that they had other customers who successfully disabled the modem to use their modem/router duo as a router and would need to go through Netgear to do this. I called Netgear for technical support to confirm this and provided the serial number. Called two different representatives and both told me it is possible to turn the C7000v2 into just a router and disable the modem. As my nighthawk was purchased a while ago, I would need to pay $49 for a one time technical support call for them to help me set it up. I don’t want to pay $49 just to have them tell me that they gave me wrong information and it’s actually not possible…One representative advised that it’s very easy to take care of advised me to do “bridge mode” and something about disabling the wifi radio? All the research I’ve done at this makes it seem like both bridge mode and disabling the wifi radio is to disable the modem which isn’t what I need. Unless I have misinterpreted the information?

Briidge mode or NAT disable or NAT OFF means that the router and wifi portion of the modem are disabled, leaving the modem portion only enabled.

You can look in the modems web page under Advanced Settings for anything having to do with Bridge mode or NAT mode.

Would be interested in what you find.

&gt; [...] need to use a modem with 3.1 or above. [...]&nbsp;&nbsp;&nbsp; Ok.&nbsp; That makes some sense.&nbsp; So, you'd need a DOCSIS 3.1 modem, andsome kind of router to use with it.&nbsp; (Or another combined modem+routerdevice.&nbsp; But you're learning just how useless one of those can be whenits modem section fails, or becomes obsolete.)&nbsp;&gt; [...] called spectrum who told me that they had other customers who&gt; successfully disabled the modem to use their modem/router duo as a&gt; router and would need to go through Netgear to do this. [...]&nbsp;&nbsp;&nbsp; As I stated, disabling the router section is possible (and supportedand documented), but how you'd bypass the modem section with only acoaxial-cable WAN port is a mystery.&nbsp; Some people claim to have seenspace aliens, too, but evidence is sparse and unreliable.&gt; [...] Called two different representatives and both told me it is&gt; possible to turn the C7000v2 into just a router and disable the modem.&gt; [...]&nbsp;&nbsp;&nbsp; Someone, I claim, is confused.&nbsp;&gt; [...] One representative advised that it's very easy to take care of&gt; advised me to do "bridge mode" and something about disabling the wifi&gt; radio? [...]&nbsp;&nbsp;&nbsp; "bridge mode" (in this context) means disabling the _router_, not themodem.&nbsp; See "_modem_ only", above.&nbsp; But that's not what you want.&nbsp;&nbsp;&nbsp; Disabling the router _would_ disable the wireless-network radios,because they're tied to the router.&nbsp; But that's not what you want.&nbsp;&gt; [...] All the research I've done at this makes it seem like both&gt; bridge mode and disabling the wifi radio is to disable the modem which&gt; isn't what I need. [...]&nbsp;&nbsp; You lost me.&nbsp; But all that "bridge mode" stuff would leave you with amodem, which is exactly the part of the C7000v2 which you do _not_ want.&nbsp;&nbsp;&nbsp; "Connect Your Modem Router [as a modem] to a Router" and "ConnectYour Modem Router [as a router] to a Modem" are two very differentsituations, and the one which you want can't be done.&nbsp; I claim.&nbsp;&gt; To use a model Cxxxx as a _router_ only, it would need an Ethernet&gt; WAN/Internet port.&nbsp;&nbsp;&nbsp; Still true.&nbsp; Contrary advice, I claim, must come from someone whodoes not understand what you want (C7000v2-as-ROUTER-only), or does notunderstand what "bridge mode" means.&nbsp;&nbsp; People ask about this possibility frequently.&nbsp; (You're not the firstvisitor here whose modem+router modem section has failed, or becomeobsolete.)&nbsp; If there were a more pleasing answer than "impossible", thenit might be much easier to find.&nbsp; And you wouldn't need to rely on thespace-alien answer, "I know that other people have done it, but I haveno idea how."
