Netgear router

There is no need to install any software to use any router in general, you just need to configure the router and you're able to plug in your network cable or thru wireless to connect to Internet.

You need to consult your router manual on how to setup the router for proper Internet connection.

Go to Netgear site to search for manual for your router model for reference.
