Motorola cable modem + wireless cable modem together?

[QueBert]

I have an older Motorola Surfboard cable modem with built in wireless, I was looking at a Motorola SB6120 today. Would this work hooked up to the one I already have? My roommate needs wireless for their laptop, and I really don't feel like spending extra cash on a wireless router unless I absolutely have to.

Thanks for the reply, I've set up wireless routers as AP's before. I was just unsure if this would work the same since the wireless router has a modem in it. I thought maybe having 2 modems together could cause problems, or not work at all. I'm not at home, but unless I'm mistaken the Surfboard with wireless doesn't even have an option to disable DHCP

I don't think a wireless cable modem will work as just a router as it'll send all traffic only through itself, which won't work. Cable modem's have no WAN ethernet port other than it's coax. You need to simply buy a wireless router. It'll be much cheaper anyway. You can't use two cable modems unless you have two subscriptions with your cable company.

Cheaper than what? it's working now so I guess I'll stick with what I got, I'm not even 100% sure a DOCSIS 3.0 modem would boost my speeds, seems like a huge YMMV out here.

Sorry, that is what I assumed. I.e., you know what you are doing and you have a Router somewhere on the Network.

In any case DOCSIS 3.0 (aka in the current time "Snake Oil") would Not do any thing for you to begin with.

People do not get it. ISPs control centrally the bandwidth. Putting a $10 bill in a bigger purse does not make it a $20.

Received mine yesterday, works great.

@JackMDS: there are many anecdotal reports of increased bandwidth via upgrading to a DOCSIS 3.0 cable modem. And: you'd also gain IPv6 compatibility, if your ISP also supports it.

I am fully aware of it. It might be that under some specific circumstances a specific individual gain from something Not even clear to him.

E.g., having new modem instead of one approaching EOL, and thus the gain has nothing to do with DOCSIS 3.0 per-se.

However, with the level of technical understanding, honesty, and objective disclosure, there is No way to evaluate most of these claims.

As long as something is on a level of Compu-Socio-wishfull thinking jargon, and it is not based on clear technological variables, I keep my money in my wallet.
