Ex6120 on iphone 7 weak security need help for firmware updates

Not sure that anyone can help much with this. Trying to pack everything onto the subject without explaining things isn't going to get us very far. That what the Body bit of the message is for.

 

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

WiFi Range Extenders & Nighthawk Mesh - NETGEAR Communities

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

 

 

What security are you using? WPA2 is standard.

there's a newer wpa3 standard but you'd have to upgrade hardware to get that. 

And apple devices are great at giving you a notice that "your security is weak" when you're not on the latest devices.

Quite a few devices still use wpa2 perfectly fine.
