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.
