The most common installation problems relate to IP Addressing. For example, without the TFTP server IP Address, you will not
be able to download the AP Image to the WL520. IP Address management is fundamental. We suggest you create a chart to
document and validate the IP addresses for your system. You can also use the form provided in
Settings.
If the password is lost or forgotten, you will need to reset the WL520 to default values. The

In some cases, specifically when a bad AP Image prevents successful booting, you may need to use the Bootloader CLI to
download a new executable AP Image. If you need to force the WL520 to factory default state after loading a new AP image,

To download the AP Image, you will need an Ethernet connection to the computer on which the TFTP server resides. This can
be any computer on the LAN, or connected to the WL520 with a "crossover" Ethernet cable.
You must also connect the WL520 to a computer with a standard serial cable and use a terminal client, such as HyperTerminal.
From the terminal, enter CLI Commands to set the IP Address and download an AP Image.
