The IP address assigned may vary for reasons connected to the wireless home router setup
(for example, a very brief DHCP lease time). If verification of the address is required, it is
usually possible to obtain the client list (and the corresponding IP addresses) from the wire-
less router administration panel.
The most common causes of losing connectivity might be: different wireless network pas-
sword, faulty or unreachable router, replacement of router (different SSID) without the neces-
sary setting updates.
Where possible, "Station Mode" is always preferable. Thanks to the internet connection, this
mode ensures better operation.
