Question Doc sys 3.1 Cable modem & POTS connectivity

[THshiv]

Hi,

I have an integrated cable modem and a Wifi router in the study. I run my POTS line from the cable wifi modem to my POTS (Plain old telephone service) line to a telephone jack close to the modem, this enables me to have the POTS service throughout the house. The issue I am having is my streaming device is in the living room with only a cable outlet.
I want to connect my ethernet enabled streaming device to be hard wired with an ethernet cable instead of the Wifi and still have my telephone service throughout the house. Any suggestions to solve this problem without running wires all over the house? Can I convert a regular cable outlet to a cable and telephone outlet ?

Best
TH Shiv

Who is your ISP? Service - DSL?

Update your post to include make and model information for modem and router or modem/router if combined).

More information needed

Connection path being the following line diagram where ----> represents an Ethernet cable:

ISP === (coax, DSL, fiber) ===> Modem ---->[WAN Port] Router [LAN Port] ----> [LAN Port] Office Wifi Access Point ~~~~> Wireless network devices

With other Router LAN ports -----> Wired network devices.

Feel free to update my line diagram to show your current configuration. Indicate wired and wireless connected devices.

Very likely that there are a number of options available. It is important to have a sense of the "bigger picture".

If you already have some diagram you can scan the diagram in and post the diagram here via imgur (www.imgur.com).

My connection diagram -

1. Cable outlet coaxial cable to cable wifi modem ( 4 WAN/ ethernet ports + 1 POTS port)
2. Ethernet ports to printer, PC, etc.
3. POTS port to telephone jack on the wall
4. Telephone jack to POTS telephone via regular telephone cable
5. Multiple telephone handset connected throughout the house via regular telephone wall jacks.
6. WAN/ Wifi Streaming device in a separate room with only access to a coaxial cable outlet.

Hope I was able to lay it out correctly for you.

Any make or model markings on that cable wifi modem?

And 4 LAN ports (not WAN) - correct?

Re: 6. What make and model is that WAN/Wifi streaming device?

Specifically identifying devices is important for two main reasons:

1) knowing their available connection options.

2) knowing the default configurations that may need to be changed in order for the device to join the home/host network.

I have, for example an Xfinity modem (XB-6A) with a single Coax input and two telephone ports and two Ethernet ports.

One telephone port serves our main handset and its' included 4 wireless handsets throughout the house. (POTS wall jacks long gone - not even a telephone cable to the house anymore.)

One Ethernet port serves the Linksys AC1900 router with 4 Ethernet ports and multiple wireless devices.

I would not expect that your existing POTS connections would be useful. Just keep that all separate as is, excluding the POTS connection at the modem.

A possible option would be MoCa. Take a closer look at and map out coax cable connections that are available throughout the house. Look for splitters, unterminated cables, etc..

And there may certainly be other ideas and suggestions.

Regular phone line cannot be used in a traditional way since it too few wires and is not twisted pair.

Best bet would be to pull a 'CAT' cable, if possible, to the LR. Might also be of consideration to utilize a 'fast' wireless option?

You have a extra cable/coax jack in the living room ?

You likely can use MoCA to get a ethernet like connection over the coax.

So if you have one of the newer fancy cable modem/routers it might already have moca support.

Otherwise you buy 2 moca devices. You place a splitter in the coax line going to the modem/router. You connect the first moca device to the splitter. You also plug a ethernet cable from the router lan port to the moca device. In the living room you hook the second moca box to the coax and then plug your pc into the ethernet port. Most modern moca can run full 1gbit.

There are 2 things to be careful of. First the living room coax must actually connect somehow to the jack that the modem coax comes from. Sometimes the ISP will disconnect these from the rest of the house when they install them.
Next you might need a filter to prevent moca signals from going outside your house. There are good diagrams of this on a moca vendor call gocoax. I would worry about this after you are sure everything else will work.

Cable wifi model is Motorola Cable Modem plus AC 1900 router with voice
Streaming device is a IP TV streaming device

 

[Ralston18]

Who has admin rights to the Motorola Cable Modem and the AC1900 router?

On a working (no problems) PC run "ipconfig /all" (without quotes) via the Command Prompt.

Post the results herein. You should be able to copy and past the results without needing to retype it all.

What make and model is the IP TV streaming device? Do you happen to know its' IP address?
