House Lan cables & Connections

[Ministik Man]

Daughter bought a new house
It has 1 lan cables (8wire) beside each Shaw Cable Coaxial cable

I spliced (twisted wires) color to color all 5 sets of lan wires together in the basement

Connected the computer to the router - computer works
then connected the router to the lan outlet in the wall on 2 floor

then connected the lan cable on the main floor to the Xbox
But the Xbox can not see the route

I moved the shaw router to the main floor and connected
from the router to the Xbox and the Xbox works
Then connected the router lan cable to the wall and computer on second floor and computer can not see the router, no connection or internet

Bought a lan cable tester and all lines are correct ---no opens, shorts, or crossovers
Tested lan jack from router end to Xbox Lan Jack all good

Not sure why they do not work


I removed the lan cable insulation but Does the lan cable wire have a varnish and other coating that would prevent a signal passing through the twisted wire connection
I see telephone and other lan cable terminated on punch blocks -- do the punch blocks scrape the wire for a better connection

Thank for your help as I can not figure this out

I didn't realize LAN was still a thing, why not use WIFI?

Hook it up to a PC then find your IP back to the working state you mention. Then do a couple of tests:

1) start/run/cmd <enter> type "ipconfig" without the quotes.... what IP does it show?
2) open a browser and go to google.ca and type in what is my IP. Are the two numbers matching or different?
3) What model "router" do you have from Shaw?
4) Can you connect the Xbox (while wired to the PC) via WiFi?
5) When you had it connected to the Xbox, and it failed, was the PC still connected?

It sounds like maybe your Shaw modem is configured bridge mode, and it's handing your device the public IP. Therefore when connecting the second device, the IP is already in use. If that holds true you can:

1. call Shaw and have them change it out of briged mode.
1b. Your Shaw account actually gives you two public IPs... you can ask Shaw to activate the second and both devices should work. (still not the best idea, having devices with public IP addresses)
2. buy your own router and continue to use Shaws device purely as a modem (it is what I prefer)
3. Use only one device at a time.... /silly idea

If a wire is available, always use the wire. If his house is wired for it, it's better than WiFi for a number of reasons.... interference..... speed.... reliability. I use WiFi on my mobile devices.... anything I can connect a wire to, I do.

Just as a quick n dirty example:

How Fast Is a Wi-Fi Wireless Network?

If the person has 802.11 AC and EVERYTHING is perfect (range, interference etc) you will get 1Gbps.... with a wire, you're practically guaranteed it. If the person has anything less than 802.11ac (b,a,n) and everything is still perfect, the best they could hope for is 1/3 the speed of a standard gigabit wired connection.

If I am reading it correct it sounds like you twisted all the wires that run to each individual jack together at one point. If that is what you have done it will only every work at one jack and one device. You need a hub or switch to split the network line out to all the jack outlets through out the house.

Brian, give me a call after 4 we can make arrangements I'll come have a look and see what we can figure out

I hadn't read it that way until now.... also a possibility. I assumed the wiring was correct.

As mentioned... you cannot splice all the "runs" together. I terminated RJ45 crystals on each cable and plug them into a 8-port switch

depending on the age of the house it could be going to a commercial punch down, and then need to be sent out from there, that's why I offered to go have a look. I used to do all that for a living.

Talked to Brian, he was given bad info and had twisted all the wires into one cable. Got him sorted out

Lol, would have never thought to ask if the wires were all spliced together.

There's something else you need to be aware of. It is not good enough to simply wire the ends pin to pin since two of the twisted pairs are split. It would still work, but not reliably due to heavy signal degradation and noise. Take a look at the color sequence of a purchased ethernet cable for reference. The color sequence should be as shown below. You'll often see the green and orange swapped - it really makes no difference, it's just color.

Also if for some reason you need a cross-over cable (although it doesn't seem like it in this case), just swap 1&3 and 2&6 on one end.
