KPN decided to limit Guest Wifi to 10Mbps and not allowing you to adjust it. People are complaining about it since at least 2 years and KPN doesn’t care. Even some people like me spent checking all settings, factory reset etc. spending hours maybe but KPN still doesn’t care about any user experience yet it’s the most expensive ISP in the Netherlands. Next time I won’t choose KPN.
Advice to KPN: At least put a note or warning in the Thuis app next to the Guest network that you have the unadjustable 10Mbps limit so that people don’t waste their valuable hours and get less pissed off.
