Security update to latest firmware for wndr3400

[Powerbean]

I bought this router in 2016 and have never had a problem with it. I have received several emails over the years from Netgear telling me that there is enhanced security updates to the firmware. To date I have not figured out how to perform these updates. My model does not show up on nighthawk and routerlogin.net will not open on safari.

So how do I update my router?

What modem do you have? 

If its connected to a modem/router combo device, you might have a different default ip address for the router. 

if so, disconnect the router from the modem/gateway. Then you can open a command prompt and type ipconfig 

the default gateway should be the ip address for the router. Try using that to access it. 

You can download the firmware and view the instructions here:

make sure you have a v1 as there's several versions. Use the drop down box to select your version.
