R8500 Constant WAN Internet disconnects/connects!
My wireless is rock solid, never disconnects. The WAN is another problem, see below from log: [Internet disconnected] Thursday, Feb 11,2016 02:35:35 [Internet connected] IP address: 192.168....

Same problem here (I started the thread) WAN disconnects.
Cable company came out and tested and replaced the Modem.
2 Hours later I had a WAN disconnect. RMA # 2 will be here today.
I never had this problem with the R7000!

Having a similar issue, although I lose both Wired and Wireless access. Sometimes the router successfully reconnects while in other instances, I have to reboot. I recently applied firmware V1.0.2.28_1.0.42 with hopes some of these issues would encounter more elapsed time between disconnects - no success. I have confirmed my cable modem is not the issue by working with my ISP during the disconnects. I am running QOS and UPnP.

Can you guys try to lower down your MTUs?
See this link.

I worked directly with my ISP to calculate the MTU rate and 1500 is where we landed. I tried lower rates, but no changes to the disconnect behaviors.
My calculation -
max packet size (ping test) + IP and ICMP headers = MTU size
1472+28 = 1500

All I am beta testing a new firmware and the WAN disconnect issue seems to be resolved!
Also the radio scheduling issue. Running abot 2 days now no WAN disconnect. Before I would
have at least 1 every 4-5 hours.
