Dear Ziggo,
I have an issue with internet connection, my setup is Connection Box in bridge mode + Keenetic KN-1810 (default settings), my connection from laptop to Keenetic is ~500-700 Mbit/s, connection speed between Connection Box and Keenetic is 1 Gbit/s however my internet connection speed is extremely low.

I have package:
INTERNET COMPLETE
Dit pakket heb je nu
350 Mbit/s download
35 Mbit/s upload
Wifi-modem
Internetbeveiliging
Installatiehulp
And there is not even close to 35 Mbit/s download speed:

On ziggo site checker speed are better but it 10 times less than stated:

Please help me to find out a reason of this strange behaviour of Ziggo Connect Box, cause on my side everything is fine, no any issues with Keenetic or my home network.
As well please disable IPv6 for my account, as soon as no any devices are using it at my home network.
