Wireless XBOX using the telco jacks or COAX in the house? Answered

Hi. I have a house built onto the top and into the side of a hill with a sharp grade. To stabilize the construction the contractor was forced to custom pour forms. The layout is a side split with a back split added to the hill portion later. The bottom level has the mechanical room and kids playroom. My son has an XBOX. He wants to play COD. We run an 802.11g router in from the ISP. i have bought an 802.11n router and 802.11n receiver. I also have a spare duplicate of the main 802.11g router. Right now my son is running a network cable from the incoming Internet through two rooms, down the stairs (poured walls) to the XBOX. i want wireless, to get rid of the cable, but the construction geometry and materials don't allow for good reception in the basement...hence the purchase of the 'n' router and transceiver. I have thought of splitting the incoming signal, and tapping into the house's phone network as the basement has RJ and Coax jacks - no gender bender (telco to network) to be found. I have thought of putting the 'n' router in the basement, giving it a static IP and changing the dynamic range on the incoming 'g' router to exclude this static IP. Still, the only way i appear to be able to avoid a wire through my house is to use the telco network inside the walls. Any thoughts? TIA. Bob?


I've got to dig into your answers but thanks everyone for giving me an education. I am impressed - big time. I'll update when I can.

BTW, I don't want to use the electrical wiring, we have dirty power here - had the hydro co in to confirm what they already knew - so I have everything on plus plus active protection.

The telco cable runs from router to the destination. The coax cable runs from a different locational source to the same destination.

Before I dig into your research which I'm about to do, is it not possible to split the incoming signal to the router, downstream of the router, establish a subnet and run the second branch to the destination.


your ISP should do that for you no hassle it cost them less (push that)
but it will work like a splitter at the entrance and then a second router downstairs
check my second comment on the topic
and I found these
and a cable form adapter
good hunting

sorry i just noticed you said "downstream of the router,"
yes easy if it is at least a cat 5e if it is let me know and ill provide instructions.

this is another proper method.
RJ11 AND RJ 45 trace the existing cable is it a 4pair utp cat3/5/5e?
for 100 Base Tx network you will need at least 2 pairs of wire.
10 base T will work on one pair so you can split the signal but be prepared for a signal slow down to 10 Mbps
1.locate a unused wall jack near one of your routers or switches.(outside end)
plug a network toner into this outlet.
2.with a network toner locate the "head" end of the cable. or service providers Entrance Facility. they should all converge in one location( EF) label it.
3.re terminate all cables to TIA 568.A or B RJ45 whatever you will be using ( think future here)they should all converge in one location( EF) label it,and the cables you toned out.
4.note on a side diagram of your space all work you do it will help you build a map of your network.
5.Locate a unused wall jack by the XBOX tone it out as well.label it, re terminate it
6.from the entrance feed terminate both cables on RJ45's and couple them together use a patch cord to jump the two don't splice. . F/m-m/F is the best set up.
or if terminated a 66 block do your cross connection on it.
you've just created a WIRED "cross-connect" structured solution to your need.
test all terminations or at least visually verify the pin-outs

The signal flow is.

if you don't want to re terminate the jacks
RJ-45 to RJ-45 RJ-45 to RJ-11

3 ------------- 3 TD- 3 ------------- 2
4 ------------- 4 RD+ 4 ------------- 3
5 ------------- 5 RD- 5 ------------- 4
6 ------------- 6 TD+ 6 ------------- 5

1,2,7,8 1,2,7,8 1,2,7,8 1,6 <- Not used

there is Ethernet over coax systems that can tie in to the same setup but instead patch cords you would use the network adapters and you will need 2 additional power sources for them
hope this was helpful,

unless I'm missing it, the RJ11 doesn't have a 5

looking at the male jack from the top with the locking tab on the bottom there will be 6 grooves usually there is only 4 pins in the jack
I_1i_2i_3i_4i_5i_6i_I the i's represent a pin or contact point the crossover cables uses the pins 2,3,4,5 black,red-green,yellow respectively to send signals over the rj45's pins 1,2,3,6 or Blue White,blue-Orange white/Orange
this is the crossover schematic there is also a link i found hope this helps


there is a couple of pictures here
there to help with the visuals

There is a type of networking that uses the electrical wiring in the house as its cabling. It used to be kind of iffy but from what I have read its pretty reliable now and reasonable in cost. From what I remember you plug the sender unit into an outlet in one room and the receiver plugs into a outlet in any other room. The main requirement is that the components be on same circuit breaker panel so the signal can travel through the house.

I've tried this for telephone and it works well for that but messes significantly with the modem/ router.

circuit sharing and absolutely no surge protectors or power purifiers or the signal gets iffy. but yes another good solution.

I did this in my condo -- the contractor put cat5 cable to all the telco jacks, and I still wanted to use the jacks for POTS phone, AND internet -- I used 2 pairs for the internet and 1 pair of wires for the phone, and it worked for 100baseT BUT every time the phone rang, it crashed the router and I had to reboot. The router never saw the phone-ring signal, it just saw the crosstalk between the wires and had a fritz.

Ethernet over Powerline is an option - but as always, expect a certain extra lag as the signal must be bridged between 2 other machines before it sees the internet.

Have you considered a directional antenna? They can offer 10-20dbm of gain by just pointing instead of spraying signal everywhere.

Wireless -- the xbox doesn't support N out of the box, so you'd need the 2 n gadgets acting as a wireless to ethernet bridge and then plugging the xbox into that ethernet.

Is it possible to move the xbox?

Is it possible to move the wifi source?

hmmm...running out of options...

...flat cat-5/6/5e cabling that runs around the baseboard and is rather well hidden once painted...
...running plenum rated cat-5 through an air duct - it's more expensive but won't catch fire until ridiculous temperatures.

You or a contractor drilling a new hole through the foundation...doesn't have to be large, just big enough for the wire or maybe two for redundancy/backup.

I found a bunch of them from several different companies.


The Netgear one has a video that tells you all about it.

And another site that did a review .
