This post describes a list of security and configuration improvements regarding Home-Router’s (e.g. Fritzbox, NetGear, D-Link)
Change default administrator password
To change the default administrator password, you need to login on your router’s management webpage. If you never done this, take a look below your router. You will find a sticker with information like: Wifi-Network (SSID), Password, WPA2-Key. Depending on your router’s manufacturer, you will find e.g. http://192.168.178.1 or http://192.168.0.1 as an entry point.
Once you are logged in, look out for the administrator password under the settings section. Change the default password into a loooooong password.
Thats it!
