If you are talking about the standalone routers, like pic related, drivers or anything like that shouldn't come into the picture for configuring it.
Just connect it to your internet cable and power it on. If you are using a laptop or mobile, connect it to its wifi network or use a cable and connect it to the lan ports of the router if on the desktop.
Then enter the addresses listed here on a web browser:
and see if a login page opens up.
Then, if you have not set up the router before, enter the default login/password info from that site. If you don't know the login and password, take a needle and look for a hole that says "reset" or something like that, and push the needle down till you hear a button click. Don't stop until the router shows some reaction.
The router then should ask for your connection details (connection username and password etc.), which you can get from your ISP. You should be also able to set up your wifi network name and password here. Click on submit and all should be well.
