    Hi goranri, 

     

    Welcome to NETGEAR Community!

     

    First of all, we do apologize for the inconvenience of not getting back to you immediately due to the backlog in the system. Are getting slow or intermittent internet connection with the DoS attack on the logs? Did you check your modem if you are having issues with the internet as well?

     

    Please do not hesitate to let me know if you need further assistance. 

     

    Regards,

     

    Oliver
