Nickoz Welcome to the community!
The signal values of your connection are OK. As a first test, we have switched your modem to IPv4, which will be completed in a few minutes. Please test it again afterwards and get back to us.
I have also noticed that you are only connected with 100mbit via LAN, although 1Gbit is possible on LAN 1-3 and even 2.5Gbit on LAN 4.
Greetings
Daniele
