Affordable Ethernet in the Living Room

Apple TVs and TiVos that stream Netflix movies are putting the stress on wireless networks. Wireless is fine for most things, but when it comes to low latency streaming, even at 802.11n speeds, things can get a little rough.

While perusing the website I discovered a cool little device: The Motorola NIM100.

These babies allow you to send ethernet packets over your existing cable tv wiring.

These devices are no longer available new, but Verizon used them in the initial rollout of FIOS and are now available used on EBAY.

I paid $88 for 3 and here is what you get:

  1. The NIM100 is a little box that looks like a cable modem, with one ethernet port, one USB port and two RF ports.
  2. A power adaptor

Step One

Now move to your office. Connect the RG6 coax from the wall to a NIM100. Then connect another RG6 coax cable from the NIM100 to your cable modem.

Connect an ethernet cable from the NIM100 to your router.

Step Two

In the living room, you connect the RG6 coax cable from the wall to the NIM100. Then connect another RG6 coax cable from the NIM100 to the TiVo cable in port.

Then you connect an ethernet cable from the NIM100 to the TiVo, or an ethernet switch.


You now have 100mbps ethernet in your living room.

Got a TiVo in the bedroom? Repeat Step Two with another NIM100. You can now send video between TiVos much much quicker than over the 802.11g wireless speeds the TiVo has.


  1. Wahlah? Ouch. It’s supposed to be a French word, Voila! Ideally, an accent on the a as well, á, but one can’t expect that to survive web posting. But please. No more wah lah.

  2. haha sorry, it is a joke for my fiancé, where I speak very bad French in a very bad French accent, ala Inspector Clouseau.

  3. Thank you for this info. Very cool indeed.

    A few questions: 1) Can the Nim100 coexist with a Cable modem based internet service provider such as comcast? 2) Won’t the ethernet traffic from NIM’s interfere with the Comcast WAN traffic?

    Thanks, DS

  4. It seems to work fine, as the NIM uses 950-1150mhz, above what Comcast uses. I have not tried it since upgrading to DOCSIS 3 earlier this week. I took the NIMs out as I was having some speed issues, which were not related to the NIMs as it turned out, but I have not put them back into service yet. Too many snow issues to deal with 🙂
