Hi all.

Is having another DOCSIS 3.0 Modem advisable with this inquiry?

I have a Motorola SBG6782-AC already up and running upstairs, wifi is alright, but I feel like I need to extend the range downstairs.

I have a live coaxial port downstairs where my hypothetical modem would be and i would like to utilize the Ethernet port for the game consoles and blu-ray player instead of depending on the wifi provided by the SBG6782-AC.

I was thinking about purchasing the Motorola SB6141 for this, but thought of asking the pros here first.

WiFi extenders? It would still be leeching off the wifi and I would really like to make use of the live coaxial port I have.

Is my theory above doable? Advisable? A bad or good idea? How do I go about doing this if it is feasible?

Your thoughts are much appreciated.

-Steve

That I "think" is directtv version of moca. I have never used it. I would assume it is similar in function. Not sure why it would be that cheap moca is kinda expensive...mostly because not a lot of people use it.

Most people use powerline networks I suppose because few people have the coax. The av2-1200 from tplink you can get on sale for $50 for a pair many times.

This only works if you are willing to pay the ISP for a second account and even if you would do that the 2 networks will be separate. A modem only talks to the ISP it can not talk to another modem.

They make devices called Moca that can use the coax. There is one of the high end motorola modem/router that has a built in moca adapter. You would still need to buy a moca adapter in the other rooms.

Moca is not compatible with many cable systems. A lot of the whole house DVR systems use the same bandwidth.

Hi bill001g.

I see. So... for the purpose I was intending the modem for, and since paying the ISP for a 2nd account is off the table, would an Ethernet to Coax Adapter work, jut like this one I found on Amazon?

Hi again bill001g.

Based on your response, the old adage of "if it sounds too good to be true..." kicked in.

You're right on the MoCA's cost and that is in fact what we have at home. That being said, "Powerline Adapters" are starting to sound really good right about now.

If and when I do get a Powerline Adapter, i'll be sure to update this forum post.

Thanks for the insight bill001g!

Those are the older models. They are a lot slower than the newer units and they have more trouble with poor wiring than the newer units. Unless the cost is a huge issue look for the ones based on av2. Even the very fastest units will only get just over 100mbit in real world installs.

Oh yes, yes, yes.

I just posted that one for anyone else browsing in here with the same scenario I'm in, just so not to scare them away from the possible cost they could be facing.

But yes, I'm looking forward to something like this...

[UPDATE: 08/21/2017 (Mon)]

To anyone viewing this with a similar inquiry:

We ended up getting Google Wifi.

This set us back around $260+ but I can assure you that it is worth it.

For anyone looking to hardwire their game console but is unable to and solely depending on the WiFi, Google WiFi is for you.

On WiFi, my game console's speedtest is at 25MBps on average. After Google Wifi (console hardwired to one of the Google WiFi ports, yes, Google WiFi has etherports) speed never goes down 90 MBps.

Our smartphones and tablets, from 77 MBps went up to 115 MBps.

But do your research, maybe it's for you, maybe it's not.
