Network speed limited to 100 mbit after placing wall socket

Hi,

Since a few months we have wired internet in our house. We have a wire going through the walls from the living room to the master bedroom. The connection for this line is working as expected, receiving 147 mbit download and 14.5 mbit upload (contract is 150/15, so everything is fine).

Since my computer is in another room upstairs, we decided to add two extra wall sockets on the wall between the two rooms. The result of this is that I no longer am able to get above 80 mbit download. Before purchasing the required equipment we specifically checked if all equipment was Cat 5E, which is the case, though, we seem to be limited to 100 mbit (as reported by Windows, speedtest shows lower).

My dad connected the wall sockets and told me he made his own order for the wires, as long as they are the same order on both ends.

Now I'm wondering, is this a possible source of my problem, or shouldn't it matter? I can provide photos later today of necessary, but it frustrates me that after doing all the work we did we still don't have the expected result.

I am sure the problem is somewhere between the socket in the master bedroom and my computer, because using a 20 meter cable to go from one room to the other keeping the cable in the gap under the doors worked fine, giving us almost full capacity.

Any tips on how I could "debug" my problem?

Thanks,

Ruben
 
Don't do your own order. You need to have the wires properly paired up, or I'd be suprised if you got any more than 10Mb/s. There's also the whole standardisation issue - what about the person who next has the place, and is lost or fries something when they re-terminate it.

Redo both ends to an actual standard, and it will probably work

Do you know where we can find the appropriate order for the wires? The packaging did not tell us. Just to clear this up, the wires have the same order on both ends of the wall, my dad made up his own order and applied it to both sides.

Nonetheless, we're changing it tonight.

After just googling I found out about T568A and B. The UTP wires I have seem to have B, not A. The wall sockets do not connect 2 PCs, but is a direct connection to the router.

Here is a photo of my wall jack. Which pin is Pin 1, and why are the color codes on here so messed up?

Neither A or B matches the colors as seen on the photo, because on my wall jack the colors are all grouped, none seperated.

Though, should I use T568A, T568B or the color coding for A on the wall jack? I'm very confused about this one. On one side of the wall there is my PC, on the other side there is a wire going to another wall jack that leads to our router. There is just one PC attached
 
A and B are equivalent, you can use either. I usually use A. Using different ones one each end creates a crossover cable, which is OK but might cause problems with really old NICs.

There's probably some rearrangement done on the PCB on that one. It's usually a good idea to have the members of each pair as close to each other as possible.
