Cable activation confirmed but no internet for 2 days

Hi community,

My official O2 Cable activation date was the 19th of May, switching from Vodafone. I have now been without internet for over 48 hours. O2 sent me both an SMS and email confirming successful activation at the end of the activation date, yet I still have no Internet connection.

My router is a FritzBox 6660 Cable using my own hardware, not an O2 rental. When logging in to my router the cable signals shows green (ok) and the router successfully reaches the O2 network (router to ISP link shows green in FritzBox GUI), but gets stuck at the ISP authentication step and never reaches the internet. I have performed a factory reset and firmware update with no improvement.

I have called customer service multiple times and was told to wait each time and that everything was looking good on their side. On my last call I was told the earliest a technician can visit is in 2 weeks, which is simply not acceptable.

What are my options here? At this point I am seriously considering whether cancelling the contract and going back to Vodafone might be the easiest solution.

I would appreciate any help, thanks.

Hello ​@souca21,

welcome to our o2 Community 🙂

That is no good development, that your new cable connection is not working.

It is good that you have reported this with our hotline, not so good if it takes 2 weeks until an appointment.

The line owner, which is Vodafone for your address is sending the technicians, so from there you will be contacted and I hope the two weeks said by our customer service were rather an estimate and it will be within a shorter timeframe.

Please keep us also updated here.

Best Regards,

Gerrit

Update.. now over 9 days without service, with the technician visit scheduled for next week, meaning I will have been without any internet connection for 15 days from my official activation date by the time someone comes to my home and that assumes the technician actually resolves the issue on the first visit.


I would like O2 to clarify the following:
1. What is the specific technical reason why my router authenticates with the O2 network but fails at the ISP authentication step?
2. What compensation am I entitled to for each day without the contracted service?
3. Given that the standard 14-day cancellation period has passed, what are my options for an exceptional contract termination due to O2's failure to provide the contracted service?


I have been patient, I have called multiple times, I have performed factory resets and firmware updates. At this point I expect a concrete response, not another instruction to wait and see what happens next.
So if there is no progress this week, I will be filing a formal complaint with the Bundesnetzagentur. In the meantime, I would appreciate if O2 could provide a temporary solution such as a SIM card with sufficient data or a mobile router to cover the service I am paying for but not receiving.

Regards.

That is not so nice that you still have to wait for the technician to come to your address to check your connection, ​@souca21.

As a temporary solutiuon you can order our Testkarte for free, which is meant to test our mobile network, has unlimited data and terminates automatically after 30 days.

With cable connections via the provider from which we rent the network, which is Vodafone in the case of your address, the technician appointment is with a Vodafone technician, so from here we can see any information only after an appointment.

Best Regards,

Gerrit
