Upgrading the Firmware
As new versions of the DWL-3500AP and DWL-8500AP firmware become available, you can
upgrade the firmware on your devices to take advantages of new features and enhancements.
The AP uses a TFTP client for firmware upgrades. You can also use HTTP to perform
firmware upgrades.

configuration information.
Use the following steps to upgrade the firmware on an access point by using TFTP:
1. Click the Upgrade tab in the Maintenance section.

new firmware image is provided.

types of files will not work.

the image to upload.
5. Click Upgrade.
Upon clicking Upgrade for the firmware upgrade, a popup confirmation window is
