We have the modem router combo C3700. Can I run a second router in my new office?

We have the C3700 modem and router combo.  We just built me an office in the garage and had a cable line put in there today.  The internet runs through that cable line.  Can I add a second router in the office or will I have to get a range extender if I want better signal in there?

Model: C3700|N600 Cable Gateway Docsis 3.0

You may be able to put a second modem router there but it will have to be provisioned as a second line of service, which probably won't be economical.

I just wanted to put a second that is just a router.  Is that not possible?

I think I had a brain fart.  I see what you are saying now and what I was saying did not make sense as the router does not plug into the cable.  I need sleep I think.  I think I will do a range extender.  There is a signal in there I just wanted to boost it as I tested it and was not pulling the higher speed.  Would an extender help that?

It might help. You would put it somewhere between the router and the garage, so that it can pull in a reasonable signal. Range extenders can suffer a pretty steep speed penalty when relaying all traffic through Wi-Fi. You can eliminate this penalty by running Ethernet from the router to the extender.

Ok thanks!  I would move the moden and router but the Tivo box is in there unless I possibly move the main Tivo and modem and router.  I work from home so I want me speed to be up to par for downloading dictations as I am a medical transcriptionist.

Downloading dictations doesn't sound like a high bandwidth activity, so you may be able to get by with a range extender.  Another option is to use Powerline to extend the network into the garage.  There are models with just Ethernet and ones that also provide Wi-Fi.  Powerline speeds are heavily dependent on the quality of your A/C wires.  Some people get great performance out of it, while others don't.  It can be a crapshoot.

 

If high-speed Internet is a priority for your garage, you may want consider moving the modem/router.  The Tivo needs Internet access for downloading programming listings and on-demand content.  If you don't watch on-demand content, the bandwidth requirements for program listings should be modest.  You could use a range extender or Powerline adapter to extend the network from the garage to the Tivo.
