I'm sorry, what do you mean with conflicting IP addresses? I've made sure to run the ISP router -> EdgeRouter connection on a different Subnet, and the EdgeRouter is the only device connected to the ISP router.
I've run a ping test for a while from the EdgeRouter, but I can't seem to be able to replicate my issues during a ping test unfortunatly. It's really quite puzzeling me
It's limited so it can be driven using a scooter license. In many European countries you can get this license at age 16. It is also often easier and cheaper to get, but it limits your vehicles max speed to 45 km/h.
