Are the devices with issues connected to the 2.4ghz or the 5ghz?

What firmware is on the router? 

What modem/gateway is the router connected to? 

When its having issues, what actual error do you get? Does it connect but say "connected, no internet". Does it disconnect from the wifi entirely? What actually happens?

    Currently running on 2.4ghz. Some of the smart plugs and smart bulbs will not work if 5ghz is turned on. I had to turn 5ghz off and leave it off to get them set up and keep them working.

    Router Firmware Version V1.2.0.62_1.0.1

    Arris TM1602 Cable modem from Spectrum

    Here's a summery of what I see happen.

    It's mostly with iPhones, laptop, and Firesticks. It also occasionally happens to our Honeywell thermostat too.

    We still have the Wifi connection icon on the screen on our iphones but can't connect to any websites through the browser. In our area, we have no cell service and use Wifi calling and internet.

    Firesticks simply says "no internet connetion" when trying to connect to directly to the router but will connect fine with the range extender, which is a cheap ZettaGuard I got free from Amazon for a review.

    My laptop simply shows a grayed out Wifi indicator with an exclamation mark in it. My laptop does not like the extender. It will connect but the connection is extremely slow. 

    When I reboot the router, everything returns to normal. All devices will connect to the router instead of the extender. 

    Thanks for taking your time to trying to help me. I am very uneducated when it comes to routers.

      2.4ghz is a very slow network and sensitive to interference. 

      If you're devices have 5ghz, that's what they should be connecting to as its significantly faster and suffers from much less interference. 

      Your smart devices shouldn't care if they don't have 5ghz whether its on or not. 

      And if they do have 5ghz, they're higher end IoT devices and should connect fine. 

      I'd try turning 5ghz back on and select a channel in thee 149-165 range for its channels. 

      For your 2.4ghz, try manually selecting a channel on either 1-6-11

        also, something to keep in mind is Netgears consumer routers are limited to 32 devices per band. If you're having 35, whenever a new device connects, it kicks an old device or different device off. Its why you have the 2 bands so you can put some on each band. Plus with 2.4ghz being slow, its better to just put the IoT devices on it. 

        So enable your 5ghz and just disable smart connect on the router. then you can setup the 2 bands separate. that might help the stability a bit.
