Moin Moin,

you have to call O2 0800 52 51 37 8 if you have a Android or Apple Phone you should use O2 DSL Hilfe App  first. This App will do some diagnostics. So you don't have to do it at phone.

You have to speak German! If not possible please ask a friend or neighbour.

Hi thank you for the information. Actually i have downloaded the o2 dsl hilfe app and follow all the instruction, but nothing solve the problem.

I guess there is a problem with the connection in my apartment and only technician can fix this.

What i told you…  “This App will do some diagnostics.”. At the end you should get a number. Will ask for the number if you call 0800 52 51 37 8 that will shorter the call.

Hi @az_ihsan 

Welcome to our o2 Community. Did you follow @schluej advice and called our technical department to create a trouble ticket to check your connection?
