Security Network key not working N750

1. what device do you have? N750 is a speed

2. what modem/gateway is it connected to? 

3. what error do you get? 

4. did you change the ssid or password? You can log into the device and check it

 

There's a support site with access to manuals, firmware, install guides, etc.
Go to https://www.netgear.com/support/
Type in your model number and from there it'll take you to the above.
Its a great resource to start with.

You are connecting wifi devices?

 

Did you set up the router?

 

Did you change the network key (wifi password)?

 

What does "not work" mean? What are you doing and what happens?

 

Then there are the questions from plemans 

 

Manuals are always a good place to start.

Visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware.

Look for the model number on the label on the device.

Check the section in the manual

Specify Basic WiFi Settings.

There may also be some helpful videos on what to do.

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

I mention it because Netgear gave up on supplying paper manuals and CD versions some years ago and people sometimes miss the downloads.
