multiple problems with xr500

Hey, First of all i have a NAS drive for my camera's but when i'm at home i cannot connect to my server with my external ip all ports are forwarded.

2nd At random times some things that are connected trough cable go offline including my NAS drive and my pc network freezes for a sec or 2 and i'm fine again and my Wifi goes to connected but no internet.

Some log:
