Firmware
Can the DWL-1800B/ DWL-1800R firmware be upgraded?
Yes, the firmware in the DWL-1800B/DWL-1800R is stored in flash and is upgraded using the
built in Configuration Utility or the TFTP server.
Can the DWL-1800B/DWL-1800R flash be erased or the firmware changed by an
unauthorized person?
No, the TFTP server in the DWL-1800B/DWL-1800R requires the SNMP write community
name (password) to perform an upgrade.
Can the firmware flash be corrupted when upgrading to a new version?
Yes, if the TFTP file transfer is interrupted during a flash update the firmware may be
corrupted. The D-Link Air Premier DWL-1800 has a backup flash, which contains the
previous version for firmware. If the primary flash is corrupt, then the backup is automatically
used to return the unit to an operating state.
When does the back up flash image get upgraded?
After completing a firmware upgrade, the backup flash containing the old firmware version is
overwritten with the new version on the new power on cycle.
Can D-Link Air Premier DWL-1800 firmware be downgraded?
Yes, an earlier version of firmware can overwrite a newer version.
Can the previous version of firmware be kept?
The previous version of firmware cannot be kept on the DWL-1800 itself, but can be stored on
your PC and loaded if needed.
Configuration
Can the regulatory domain (country) of a DWL-1800 unit be changed?
No. The regulatory domain is factory set.
How can the DWL-1800 be configured or managed if the SNMP Community name has been
forgotten?
Press the reset button on the top panel with a paper clip. This will set the read and write
Community names to public and private, respectively.
How can the DWL-1800 unit be returned to factory default settings?
There are two ways. One way is to use the Default button on the Station Control Tab in the
DWL-1800 Configuration Utility. The other is to press and hold the reset button on the back of
the unit while powering on the unit. Remember that all settings including IP addresses will be
lost when setting defaults.
