GRUMBLE GRUMBLE @ R8000

I would have returned the router by now, but the likelihood of getting anything except stares from the store I purchased it at, I would be laughed out of the store.  It seems Netgear routers have a habit of breaking down after any kind of warranty is about to expire.  I am on the remainder of my hardware warranty for this router.  This has taught me a lesson - never ever buy Netgear products again.  They are a headache and a piece of crap (I could fill in an expletive here but it would cause the message to be deleted.)  I only have several devices (1 computer, 1 wifi printer, chromecast, bluray player & a tv - not an exhaustive list of hardware which this router should be able to handle easily.  By the way, I did as you had suggested - reload old fw and then add one device at a time and NADA.  I asked for Netgear tech to call today, not a peep from them.  I called in again, trying to reach the tech that I had been dealing with and I got a person saying she would relay the message and wait 24 hours for a call from a tech. GRRRRRRRRRRRRRRRRRRRRRRRRRRRRR!
