@Problemos Can you post your line parameters from Internet / DSL Informationen / DSL included the DTU errors? Thanks!

@Joe Doe I mean this screen. 
 

@Problemos Please turn off your router, reconnect several times the grey dsl cable to TAE connector box and than turn on the router again. (No Joke. Helps sometimes by connection)

You have to much DTU errors. 
Hope the power supply from the Fritzbox is alone the power connector and you don’t use any powerline adapter in you apartment.

I tried other sockets in the apartment, other dsl cables, but the problem remained, only the intervals between disconnected internet became less frequent

@Problemos You have more than one working TAE connector in your apartment?!? 
Than I think we habe your problem. Can you make some pictures from each open TAE connector. I want to see the cables inside and what pins are connected.

Thanks.

Hello @Problemos ,

welcome to the o2 Community .

Have you changed anything about your connection yesterday? Unlike before in the last 24 hours there were no reconnects and interruptions of the DSL that we can see on our end.

Kind regards, Sven

out of desperation i tried another socket from other room at home and then everything got better, now my apartamens with a lot of cables on the floor‍♂️

@Problemos I think in your apartment is illegal parallel connection from the TAE connector boxes. This causes your stability problems with the SVDSL sync.

Hello @Problemos ,

that definitely sounds like an issue with the cabling within your apartment, which is something that we can’t really do anything about, you’d have to talk with your landlord about these and if he’s willing to get an electrician to take a look at the connection to this second phone socket that seems to be the issue here.

Kind regards, Sven
