Internet disconnects daily after upgrading the speed

Hello,

I have recently opted for the “faster internet-100Mb/s” service via MijnKPN. I received a new modem (Experia box V10) and a mechanic was sent to my home to install and upgrade my connection.

But ever since my internet was upgraded, I am experiencing at least 1 internet disconnection per day. The service light turns orange and the internet light turns red. Then it randomly connects again after a while

Could you please check to see why the connection has become so unstable after the upgrade? This has made it very difficult for me to work from home

In case this is helpful, Below is a typical example of my modem’s “service log” everytime the disconnection happens

I appreciate any help
