Your router is a gateway to access the internet. You can access the settings by typing the IP address of the router into the address bar of a new webpage.
By default, the router IP is 192.168.1.1 and the password is ‘vodafone’. This will take you to the router home page which you can access and change settings for your Wi-Fi, LAN and connected devices, as well as manage firewalls and follow diagnostic steps. The router can send the Wi-Fi signal to your chosen device to improve performance where needed.
