192.168.l.l (sometimes referred to as 192.168.l.l), is the default router address. By accessing this address it is normally possible to access the configuration and modify each connection parameter. The address is a private or local IP address, this means that addresses of this type are not unique in the Internet. While in LAN (local area network) they the router. If the router does not have this local address then it is always possible to try the equally widespread

What can I do by accessing

- See connected devices (both via cable and via wifi) - Configure the wifi (frequencies, access password, key protection protocol) - Configure the internet router access parameters - Modify security parameters - View any transmission error percentages

What to do if I can't log in?

It is possible to try with the default password. It is always good practice to change the access password. If you still do not remember the password, you can always press the reset button and bring the router to the factory settings (including the password). Vodafone usually distributes proprietary routers which however have a configuration very similar to modem routers of other brands.

The following is a list of default user names and passwords for the main brands on the market:
- Vodafone admin admin
- 3Com admin admin
- Belkin admin admin
- BenQ admin admin
- D-Link admin admin
- Digicom user password
- Linksys admin admin
- Netgear admin password
- Sitecom sitecom admin
- Thomson user user
- US Robotics admin admin

What if I don't know the router address with certainty?

In windows you can get the correct address by typing cmd and then from the command prompt ipconfig (the address is indicated as the default gateway address).

Some common addresses besides or are the following:

Many routers allow you to change firewall settings. The firewall allows you to have a protection from the external environment and serves to protect the devices connected from malicious attacks. Normally in routers it is possible to enable / disable or change the security level of the firewall.

Very important and useful is the port mapping or NAT service provided by the most common routers. Port mapping allows the transfer of packets through a specific communication port by forwarding the correct service to the device that needs it. In particular, for gaming or VoIP setting this function is necessary to avoid communication problems that would compromise the use of the service.

In the DHCP settings it is possible to change the address set of the connected devices. The possible IPv6 configuration tab allows you to enable or disable the use of the new IP version 6. IPv6 will replace the current IPv4 in the future. The address is one of many IPv4 addresses. They consist of 4 blocks of numbers. IPv6 addresses are instead formed by four blocks of hexadecimal numbers.

It is possible to change the default DNS servers and NTP servers. DNS is the service used by any browser to access a web address. Since each web address is part of a domain and each domain is hosted on a server reachable through an IP address, the DNS is like a telephone directory that provides the IP.

Some routers allow you to set access filters based on the MAC ID of the authorized devices. In practice it is possible to list the MACs of trusted devices to allow them to connect and leave out all unknown devices.

Finally, some routers have other settings such as: Quality of Service (QoS) management and WPS blocking.
