I have quite strange issue. I've bought new D-link router I can manage at 192.168.0.1 - I can log in into router interface but for some of subpages (in fact for most of them) I'm getting "Router not found". I'm using Wifi.
I've verified it on Ethernet on Windows - it's working fine. I've also verified it using Wifi on Windows tablet and it's also working fine.
Can be any MacOS system setting that is causing problem with this? Everything else is working pretty fine - I have connection to router all the time, Internet is working also fine.
