System Software: Upgrade - HTTP Upgrade
 

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

The version of Cisco IOS software that is running on the access point.

Bootloader Version

The version of bootloader that is installed. The bootloader does not change when the system image is changed.

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. Go to Cisco.com and download the newest system software version to your local drive. Click Browse, locate the new system software file, and click Upload to copy the file to the access point. Upgrades may take several minutes to complete and can cause the access point to reboot.
