• Upgrading from v1.0.x.x to 1.1.x.x/1.1.1 is a two step process requiring the same upgrade
procedure to be repeated twice. The first upgrade will result in a bootloader change, and the
second upgrade will result in a firmware change. For subsequent upgrades, a single
download will suffice. Using Auto Update, the access point will automatically update itself
twice when upgrading. Upgrading from v1.0 to v1.1/v1.1.1 retains existing settings. Symbol
recommends that users export their 1.0 configuration for backup purposes prior to
upgrading. When downloading from v1.1.1/v1.1 to v1.0, all configuration settings are lost
and the access point returns to factory default settings.
