Moin Moin,



is the connection slow with cable or with WiFi?



If the connection is slow with WiFi could you check it with calbel?



if only the WiFi connection is slow that try a nother channel.



You could restart the router remove power from the router for 5 Minutes an reconnect.



Manuales could find at Router Anleitungen und Handbücher: Hilfe im o2 Service ansehen
