Wifi performance suddenly poor
I have been using an R8500 and a EX7000 extender for some time with good performance.
In recent days (possibly following an update of the R8500), performance on the 5GHz channels has become terribl...
Forgive me for replying to the wrong party.
Thusfar, the behavor and issues you are describing are often the result of bad FW flash or misconfiguration. Its good that you have disabled WiFi and DHCP, etc on your ISPs modem, but you should really look at getting in into Bridge or Pass Through mode. No way for us to rule out this not being related to your issue(s) unless this is done. The 8500 needs to be running the show. I recommended taking the extenders out of the mix (for now) because you have zero stability from a performance standpoint.
Flashing FW - should only be done from a PC connected via ethernet. Genie or automatic update might work 90% of the time, until it doesn't. Eliminate as many variables as possible.
Reset, good idea. Now use an app to see what other networks are broadcasting in your vicinity, and what channels they are using. Choose something else.After saving, I suggest fully restarting your router before testing again. While its not alway neccessary, I've found it to be reliable.
QoS - Avoid it. You're asking for trouble.
Smart Connect - Also not a fan... Why not create your own networks, name appropriately. Connect your devices based on capabiity. Also gives you greater flexibility with channel selection. Up to you. But remember, if one of your 5Ghz devices get put on a 2.4Ghz broadcast, performnce is going to suffer.
You've got some more troubleshooting to do. I've not had a router forget its port forwarding or address reservation settings once set. Hope you;ll figure it out.
Have you connected any new devices to the network when you started to see this happen? Have you tried to resync the extender?

Hi Darren,
Not before the problem started, although since writing this, I have tried many things, including replacing the EX7000 with an EX8000; and yes I have resync'd it very many times. I even tried contacting Netgear support, but they were less accessible than the crew of the Marie Celeste.
I am pretty sure that the problem lies with the router.
Yesterday I noticed that the table of attached devices was shuffled.
The device names and types were not those of the IP address and were changing each time I went back.
I have switched off QoS as this shuffling was causing mayhem - putting the extender on low priority for instance.
In the end, I did a full factory reset of the router, but that did not change the firmware and the problem persists.
