To access the router login screen, open a browser and connect using one of these three URLs. Try each of them to see which one brings up the login screen for you.
http://192.168.1.1 http://192.168.0.1 http://tplinkwifi.net
Once you’re logged into the router, you can change the admin password under Management > Access Control > Password.
Congratulations! You're logged in and ready to go.
