Additionally, the configuration version can be manually changed in the text file to cause the
configuration to be applied when required. The parameter name within the configuration file is
“cfg-version-1.1-01.” The access point only checks the two characters after the third hyphen (01)
when making a comparison. Change the last two characters to update the access point’s
configuration. The two characters can be alpha-numeric.
Upgrading from a legacy to a new firmware version 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 the actual firmware update. For subsequent upgrades, a single download will
suffice. Using Auto Update, the access point will automatically update itself twice when upgrading.
Upgrading to a new access point firmware baseline does not retain the configuration of the previous
(lower version) firmware. Motorola recommends users export their 1.0 configuration for backup
purposes prior to upgrading.
When downloading to a lower firmware version, all configuration settings are lost and the access
point returns to factory default settings of the lower version.
For detailed update scenarios involving both a Windows DHCP and a Linux BootP server
configuration, see
Configuring Automatic Updates using a DHCP or Linux BootP Server on page B-1 .
CAUTION If downgrading firmware from to a lower version, the access point
automatically reverts to default settings of the lower version,
regardless of whether you are downloading the firmware manually or
using the automatic download feature. The automatic feature allows
the user to download the configuration file at the same time, but since
the firmware reverts to the default settings of the lower version, the
configuration file is ignored.
NOTE An AP-5181 does not support any firmware versions prior to 1.1.1.0.
