KPN Internet keeps disconnecting

Hi ​@fritzkohle . Welcome to the KPN Community.

Thanks for your message. That does sound quite frustrating, especially if it keeps coming back after a reset.

To help us narrow things down a bit, could you tell us if you notice any changes in the lights on the fibre box or modem when the connection drops? Also, are you connected via cable or Wi-Fi, and do all services go down at that moment or just the internet?

With a bit more detail, we can better determine whether this points to the modem or something on the network side.

Thanks for getting back.

This is what happens. The Internet light on the modem flashes when the internet is down. So then we reboot everything, the glassfibre connection modem and then KPN router 12. 

Your colleague from KPN has send us a now power adapter for the router 12, but it does not make a difference. Internet stays stable for a while when we do a factory reset (the small pin hole button in the back of the modem) but it does not return to the factory settings and instead returns to the old settings. after a day or so the problem returns. 

I hope that gives you a better idea.
