Hi. I have my ATV4 connected via Ethernet, all working fine. But if I leave it for a couple of hours and come back the network drops, no assigned IP address from the router. I then have to go through a song and dance of rebooting the router and ATV4. Never had this on the previous ATV3. Is this just me or has anyone else experienced this behaviour. P.S all other connected devices to said router still work.
