Hello @yarenduygu,

Do you generally have no internet? Or just not via WiFi?

Best regards

What is the brand and type of the router?

Couldnt understand your question exactly but I guess just not via WiFi. I connected my router but there is not internet connection although my router's wlan lights is green. Till Today morning I have no problem about internet.

Fritzboxbox7590 HG

Please send us a hardcopy of the screens below.

Übersicht / Overview, DSL (all pages) Spectrum and Statistik.

@yarenduygu First you can switch to English language menu in the Fritzbox.

And did you see an online connection under Internet/Onlinemonitor

OK. I am missing Übersicht. But there is a DSL Sync. There is only a WiFi problem between the FRITZ!Box and maybe the repeater.

WiFi is enabled on the FRITZ!Box? If you are near the 7590 could you see the name of you network in you phone wifi list? Have press the switch on the to of the 7590 to disable the wifi?

Have you done the things listet her:

There is no repeater. I just have router Fritzboxbox7590. That is why I can not understand. I understand I need to connect repeater to LAN.but I dont have any device as a repeater. I just have this router.

Than check the wifi option of your FRITZ!Box. Change the WiFi name of you FRITZ!Box.

Maybe the repeater belongs to some one else if it is not your repeater.

I changed my router name. Now I am not

seeing any repeater but still there is no internet

@yarenduygu I'm afraid that at the end of the week a Telekom technician touched your connection while another customer was switching in the DSLAM, so that you are now offline. (Despite DSL sync). We say to this „Verschaltung“ Did you have entered your o2 DSL Username and Password under Internet/access data in the Fritzbox?

You mean this 

What should I do now?

@yarenduygu This is NOT correct! You put there the wrong data. The o2 dsl username include @s93.bbi-o2.de

Look in email or letter post you get from o2.

Everthing is fine now thank you so much for your help :)

Welcome to the Community @yarenduygu.

I'm very pleased to read that you were able to resolve your issue here with the help of joe Doe and schluej.

In this case, was it really just the wrong DSL username?

Kind regards
Steffen

Hello, yes when I change the username it works properly but I still dont know how did my internet suddenly break down when there was no problem. Thank you for your team’s help

Sincerely

Yaren

Hello @yarenduygu ,

what exactly was the issue with your connection is hard to tell after the fact, but as this was seemingly fixed on it’s own I think the guess from Joe Doe that this was a issue with the ports ending up switched between you and another person is the most likely.

Kind regards, Sven
