This post is not exactly full of information needed for a reply.
First this is tagged with the words support and tor-browser. The title of the post also says browser so I am guessing you need help with the Tor-Browser.
Download the tor browser from this site and install. There different versions: Windows, Mac, Linux, and Android. Now when you surf the internet your router is a “tor router”.
Does “convert my router into a tor router” mean a you want your router to be a Tor relay? Then you probably need DD-WRT. Search for “install DD-WRT on a router” either here or on the whole internet. There are downsides to using your home router as a tor relay.
