I have Edge Pro 8 with 1.7 version firmware. My problem happens sometimes, every one or two months. I resolve by reboot router.
One computer suddenly stop communicate with router. Any ping to router not responding. When I change IP on this computer then everything is OK. When I use assign problematic IP to another computer then this computer also has a problem with communicate. Where can I search a problem on router? It looks like something block this IP on Edgerouter.
