We're also experiencing issues with routers giving this error as well. Any word on what's going on?

After attempting to resolve this for weeks and changing one setting at a time, I have found that the new 4.6-R8 firmware along with disabling IP conflict detection has resolved the WiFi disconnect problem. IP conflict detection isn't necessary to have enabled. I have found that at least one device would disconnect every 10 minutes or so. IP confilict detection interval was set to 600 seconds which would explain why this happened every 10 minutes. 

Thought the whole time it had to do with not having enough DHCP leases. This has been tested at my own house along with 2 customers that are trusted sources and were messaging me about wifi disconnects daily before these changes, changes were applied 1 week ago and no issues yet.

IP conflic detection is found under the Network - Advance tabs.
