No internet since yesterday evening

Last night my DSL started malfunctioning. I run o2 test app and it shows that router is working fine but my connection is extremely slow - 0.01Mbps. 
I tried to call helpline but I can’t connect to anyone . 
My case number 900 042 700 811

Hello @Maciej84 ,

welcome to the o2 Community 💙.

From what I can see your connection is up and running. Are you maybe experiencing an issue in the connection between your router and whatever hardware you are using? Are you just using WLAN or do you also have anything directly connected to the router itself? Have you checked if there is anything notable within the logfile of the FritzBox through its GUI.

Kind regards, Sven

It started working again this morning , issue solved itself
