Cable Modem Question

Question

I purchased a NETGEAR Nighthawk AX6000 WiFi 6 Router (RAX120) and it is being delivered tomorrow or the next day. I have am using an old NETGEAR Cable Modem CM600 right now hooked to my current router which I am replacing. My brother has a brand new AC1750 WiFi Cable Modem Router (C6300) in the box that he isn't going to use and said I can have it if I want it.

Can I replace my current CM600 Cable Modem with the C6300 Cable Modem Router and use that with my new RAX120 Router or will it not work since the C6300 is a modem/router? If I need to use my CM600 can I use the C6300 as an extender to boost the signal in the house and place it somewhere else to help with the signal?

We have a 2 story 4,000 sqft house and the router is currently in the the downstairs corner of the house.

Thanks.

Thanks. &nbsp;I'll stop by my brothers this weekend and grab the cable modem router to check the exact model. &nbsp;Pretty sure it is the C6300 and not the C6300v2.&nbsp;I think if I try replacing my current modem that I will try to disable the C6300 router and use it just as a modem and use the RAX120 as my router being that it supposed to have a larger range than the C6300.

The V number is almost certainly a red herring for cable modem/routers. Unlike DSL devices these modem/routers are mostly beyond your, and Netger's control.
&nbsp;
Both have similar instructions for switching modes.

Beyond&nbsp;using more electricity, not sure what you benefit would get replacing a modem with a modem/router with the router bit disabled.
&nbsp;
I intervene simply to add my own experience of doing just that, albeit with a DSL modem/router.
&nbsp;
When a modem starts, it has to go through various internal checks and then negotiate a connection with your Internet service. Only then does the modem bit get into a state that your router can recognise and connect to.
&nbsp;
After unexpected power cuts, I found that a modem/router in modem only mode took so long to connect that the router sitting behind it threw up its hands in disgust and refused to hang around waiting. It just timed out and went into a sulk, leaving me with a dead network.
&nbsp;
By contrast, a simple modem only box behaved itself as expected.
&nbsp;
I'd certainly expect the the RAX120 to have several advantages over a modem/router in the wifi front. Whether or not you'll notice them is a different matter. The good news is that after a rocky start – you should see the anguish they caused&nbsp; here – those RAX devices are beginning to bed down.

&gt; The V number is almost certainly a red herring for cable&gt; modem/routers. [...]&nbsp;&nbsp;&nbsp; When seeking/selecting documentation, if everyone uses the same modelnumber, then everyone should be looking at the same documents.&nbsp; Accuratedescriptions are seldom useless.&nbsp; Unlike lame advice.&nbsp;&gt; Beyond using more electricity, not sure what you benefit would get&gt; replacing a modem with a modem/router with the router bit disabled.&nbsp;&nbsp;&nbsp; Because every modem is identical with every other modem?
