Hi @heich,
I do not have information on how to troubleshoot those devices but if its having issue connecting to the modem/router, I recommend to contact the manufacturer support to avoid incorrect troubleshooting.
I ran an initial test again to the service it shows no line fault and connected for 1h 30m. When you say the Internet and WLAN leds are frozen does it mean its LIT UP? Because if its yes, it means the internet is working fine. It is possible that the devices that you are trying to connect is having issue to connect wirelessly.
Try to connect the LAPTOP directly via LAN/Ethernet cable and let me know if it will experience dropout the same with the other devices that is having issues. In the event that only the wireless devices are having issues with the connection to the modem, try to follow the troubleshooting of these articles.
On the other hand, I will raise this to the assigned Complaints Resolution Case Manager handling this case for additional reference.
Just now I tried to connect to the internet and my LAN devices and once again the internet and WLAN LEDs are Frozen cannot connect to the internet and my Local devices. Now getting pretty pissed with this and ready to throw it into the rubbish.
Regards
Henry Przybycien
