An HTTP upgrade requires you to load the image into the access point memory. If there is not enough system memory for an HTTP upgrade, the upgrade fails. If it fails, try using TFTP upgrade or upgrading HTTP again after disabling the radio interfaces, shutting off high memory usage features (such as WDS), and rebooting.

System Software Filename

The software that is installed on the system.

System Software Version

Upgrade System Software Tar File

To install a newer version of Cisco IOS software, insert the correct path and filename of the new system software tar file.

Upgrades may take several minutes to complete and can cause the access point to reboot.
