Hello @Sancy,
welcome to our o2 community 
I am sorry to hear that you have problems with your internet connection. These disconnects can have many different causes. First of all, please check all cable connections for loose contacts. Please do not use extension cables or multiple sockets and only use the original cables if possible. If the cables are all okay, please perform a power reset: To do this, pull the plug of the switched-on router from the socket for 1 to 2 minutes. After restart, the connection should be working again.
If this doesn’t help please call our support and report the problem. They will inform you about the further procedure, a technician may have to come. The staff will then arrange an appointment with you directly.
Please let us know if you have further questions.
Best regards
Giulia
