Hello, I got some weird issue. Some days ago my old router died. The IP Adress of my old Router was 192.168.15.1. And since my old router had the same IP i didn't expect to have issues. However i don't have internet access on my Fathers PC anymore. The settings are: IP:192.168.15.5 Gateway:192.168.15.1 DNS: 192.168.15.1 Submask: 255.255.255.0 Which i expect to work? However i only seem to get internet on his machine when i change his IP to 192.168.15.6 If i change it to 192.168.15.2-192.168.15.5 no internet again. I wonder how that is even possible since we only have 2 PCs connected to the router?
