high-speed Internet and network connections. You can activate/deactivate the Wi-Fi mode on
the IP phone, and then connect your phone to the desired wireless network.
Note
The wrong network settings may result in inaccessibility of your phone and may also have an
impact on your network performance. For more information on these parameters, contact your
