No! Don't take it wrong, please also see my previously uploaded photos (meshign.ir/bb.rar)

In the old images, you can find a image named "Master Socket (In a room)". That is where the master socket starts, and in the new archive (bb2), you can find the Wiring 1 & 2 images that show where the wires shown in the "Master Socket (In a room)" image goes.

The socket that had a socket doubler on it from the previous resident isn't the master socket.
Wich socket should I unscrew and take image of? The master or the one that has the doubler?

Ah, you have a diff. IP. Try this link now: http://192.168.1.1/setup.cgi?PATH=/bin:/sbin:/usr/bi... as I've changed it for your IP. This should be our last attempt.

I just see "Ping Results" again and a box under it that is empty. Still nothing in it...

One more thing: Is it possible that I get 2.6-2.8mbps speed again soon by connecting the filter directly to the socket? (Not using the doubler)

Anything is possible, at present we have no idea of what your wires actually do

In an ideal world you would take pictures of every socket opening them carefully.

Then draw a sketch tracing the cable as it comes into the house, and showing how it runs to the various sockets. Pictures avoid you using the wrong names for things, i.e. you know what you mean, but we may mis-interpret the word.

Without seeing the wiring, the term master socket is simply a phrase you are using, by tracing the wiring from outside to inside we can figure it out. It is POSSIBLE for the white cable to go into a socket and out again, and the next socket down the cable be the master, known as back wiring using a spare pair of wires inside the write cable.

In short the white cable carries 4 pairs of wires that can be wired up in many configurations.

Well doesn't only the master socket have a test socket beneath it? As the old socket my filter was connected to didn't have a test socket when I unscrewed it. But the one in the room that is where the cable comes in from the hole does have a test socket beneath it if I unscrew it.

Soon I will upload pictures of the sockets and upload it for you guys.

To enable debugging
http://192.168.1.1/setup.cgi?todo=debug

Then
telnet 192.168.1.1

Enter login details
Then

adslctl info --stats

In THEORY the master socket will be the one that has a test socket under it, but based on memory from the two sets of photo's I've seen I don't recall seeing what looks like a traditional master socket, where the small faceplate unscrews to reveal the test socket.

I may have missed that picture.

I said theory, as your wiring may have been fiddled with over the years to make the master socket a different one in the property, or someone just put a master socket into a location where it really should have been an extension socket.

Some pics of master sockets here that may help

From what he says he has already done that.

You shouldn't need to login for TELNET as it is done in the enabling phase. I never need to, but he is saying he is prompted to and it is failing.
