Change the WEP key

The first solution requires that you get to connect to the WiFi router.
To do so, open the browser and connect to http://192.168.1.1 or http://192.168.0.1!

Under the menu, go to the security tab and change the key to secure your wifi.

Reset WiFi router

If you also have forgotten the password to your WiFi router, the first solution is to try ID and default password as specified in the router's documentation.

If it does not work,reset your access point or your WiFi router with the help of default settings. To do this, see your hardware documentation. On almost all routers, there is a small hole for resetting the router.
