I installed Kong dated 1-18-2017 onto my R6250's. Everything looked good, ran great and later in the evening after about 6 hours the routers crashed. Lost internet and unable to access the router. Only way to gain control was reboot, which took longer than usual. I reset the router and reconfigured only to have it do it again. So I loaded the one dated 01-14-2017 and it ran perfect with zero crashes. I let it run for days then reinstalled 1-18-2017, later that night the routers crashed. Figuring it was the routersbeginning to fail I reinstalled Netgear and they ran fine for 5 days. Two days ago I reinstalled 1-14-2017 and both routers have been running fine. Never had an issue with Kong's firmware before.
I installed the latest update dated 02-03-2017 early this morning and everything is working good. No crashes and I can still access the router.
I installed the latest version dated 2-3-2017 and my main router crashed again. So I really don't think it's Kongs firmware. I am replacing it with a Asus RT-AC3100 with Merlin installed.
