ADSL works on DTI but not on other wall sockets.

Hello everyone,

I just moved into a new apartment, unfortunately when I tried to connect my internet box (SFR) ADSL to a wall socket in the living room, I couldn't get internet.

After talking to SFR technical support, they had me test the internet through the DTI and miracle, it works.

I then tried to connect my box to another wall socket after removing it from the DTI but that doesn't work.

Below are photos of the connection in the DTI box:

Thank you in advance for your advice so that I can have internet through the wall sockets.

Best regards,

jérémy

Hello,

it looks like the wiring on this DTI is correct.

I think the DTI is defective.

Start by only connecting one cable from the DTI to the outlet you need, because 4 floating outlets like that act as an antenna and seriously disturb the ADSL signal or even worse VDSL.

Remove the 4 cables coming out of the patch and instead use a RJ45 cord between the test outlet and the patch that corresponds to the outlet you want to use.

That said, if your wiring is done correctly, your box would be better installed at this cabinet, supplying the 4 outlets with ethernet.

PS,

was it you who asked for that yesterday?


And there you go ....

But darn, those line breaks are so annoying!!

Thank you for your response.

I connected a gray cable coming from the DTI to one of the patch panel sockets (I tried the 4), it doesn't work with the BOX connected via Ethernet cable from the socket in the living room...

In that case, I have 2 possibilities if I understand correctly: either to run an Ethernet cable from the test socket to the patch panel socket corresponding to the socket in my living room, then run another Ethernet cable from that living room socket to my BOX?

Or run an Ethernet cable from the test DTI socket and connect it directly to my BOX (which works currently), then connect an Ethernet cable to each of the sockets of my box and the patch panel as shown in the diagram?

PS: No, it's not me :)

Thank you

In my opinion, the second option, unless it poses a problem for the Wi-Fi network, is the best and your test confirms that the DTI is defective.

After that, your wall sockets' wiring needs to be complete and correct, not just set up for the telephone, especially since it doesn't work for the phone :- (

Hello everyone.

A DTi can be easily tested visually or with an ohmmeter. There's not much inside. The last DTi I repaired was in the female RJ45 socket; one contact wasn't making contact when the cord was pulled out, it was missing a millimeter to make the contact, it had loosened. I took my soldering iron, disassembled the socket, and tightened the contacts.

Now a DTi box isn't expensive and can be changed easily.

Repairing or worse, replacing a DTI in 2022 makes little sense, especially when the test socket is working:

1- only one connection to a box is possible (end of PSTN) and connecting multiple cables penalizes the xDSL signal (radio frequencies can create antenna effects with reflected signals if the socket is not loaded).

2- investing in a DTI when we will likely switch to fiber in a few months is not a good idea, it will be completely useless afterward.

So connecting directly to the test socket on the home wiring, if we absolutely want to move the box, is a good workaround, provided the home wiring is correct.

Moving the box is not a good idea either, still in the perspective of the upcoming arrival of fiber.

I understood that the test socket only works if the RJ45 cable is plugged in.

Well, for the fun of it, I would have repaired the DTi. Some time ago, I bought a new one. Brand new and installed, it was faulty. Rather than returning it, I repaired it. The seller was quite happy with my operation.

Fiber isn't coming anytime soon for some. One of my friends eligible for fiber received his Livebox 5 almost two years ago. Despite his numerous efforts, he still hasn't been served, and it's not expected in the coming months. He's still on ADSL.

Well, plugged into the test socket, yes, that makes sense, it's not easy for it to work if we're not connected to it :-)

However, what is certain is that when we connect to it, it cuts off all the outputs, but you know that since you fixed the contact that cuts it off ;-)

But this functionality is no longer useful today.

PS, I'm also waiting for the fiber, but they are currently laying the cables in the street, just waiting for them to install the PBO, then in principle, 3 months later, if everything goes well.

It smells good :-)

Personally, I received my Box on May 5th, I was eligible. On May 24th, I was served. I attended my entire installation, which was two hundred meters from my home. The guys are well-equipped. Between the sidewalk and my place (less than ten meters), there were no issues. I was satisfied with the work done in two hours.

DTi: it's just simple switching.

One input, one output, one test socket.

Thank you for your replies!

I tried the second solution, connecting the DTI test socket via Ethernet to the box, and then coming out of the box to the patch panel via Ethernet. I tried all four and all possible configurations, but the internet does not reach the living room!

Does that mean the wiring in the house is not good?

We agree that from the living room socket, I exit with an Ethernet cable and not with a smaller connector (phone?)?

Thank you

Jeremy

yes, absolutely, you also need to connect with an RJ45.

have you tested connecting an RJ45 from the test socket to the patch panel and the box in the living room?

Thank you for this advice, it works on the living room socket, so it's the DTI that's not right?

Also,

but your wall socket wiring shouldn't be done for Ethernet either, just for the phone :-(

If you want to put your box in the cabinet, you will probably need to redo the socket wiring.
