ethernet cablles meaning of colours?

[boof]

i'm trying to connect between NBN modem and TP-Link router.

a new cat 6 blue cable with clear RJ45's does not connect.
are the yellow cables with yellow RJ45's wired differently?
what about red ended cables?
thx

On BOTH your modem AND your router, when the cables are connected, the light at each port would light up. If that has occurred, then they see each other over the wire. And, whenever there is traffic between them, the port's light flashes.

Are you seeing this behavior?

I have used ones that are black, yellow, gray, blue.

As long as the packaging does not say it is for some very specific purpose.
Any will work.

How do you know it is not connecting?

You do what?
You see what?

Color is more about running long cables or where you have a bunch all together.
This color is for cameras.
This color is for internet connection.
This color is for printer connection.
Etc...

The cable that comes with routers I have purchased.
I have gotten blue, yellow, gray, and black ones.

Sorry have to ask.

Sure you are plugging into the correct Ethernet connection?

Should be one connection specifically for the input to the modem.
Other connections for output from it.
Hopefully the input is a different color from the outputs.

i have disturbed my cables, and now have LAN but no internet connection. i'm using an NBN modem, new, and its utput is port 2 with belong. can't easily bend down get on floor to proove that. its in 3rd from right. there's wiring in the walls of several rooms, 2 in one, but i don't know how the ports are connected. no map. i have a tracer, but have no-one to use it for me. apparently, ethrnet cables are point to point, not daisy chained. i have 6 other wifi networks here, which is why the house is hard wired. my wifi straddles 3 other networks, at twice their amplitude. v broad bandwidth hog. i didn't know that when i bought it.

I think we need a bit more information @boof to get you connected.

Does your setup look anything like this?

You got all of that and you think we can figure it out

Very good image to show connections.

I was going to ask, if your NBN had all the same color Ethernet connections.

As shown in the image, your output is the number 1 connection.

If you are going direct Ethernet, to the computer, from the NBN.
That yellow cable, should just be hooked to the computer Ethernet connection.

You can have bent contacts in a Ethernet connector.
Not so much the cable plug, but the connector it plugs into.

fixed-sort of. the cable was bad. i have to trace my cabling. then maybe i can use it. should have it done this week. it would be easier if i put an RJ45 male plug on the tracer's RJ11 fitted telephone wire, but i have dead cables i can cut the ends from and twist bared wires. job for later. thx for help.
