: Identifies the hardware series compatibility (2802I, 2802E).
Whether you are upgrading to this version or rolling back from a later AireOS version, the update process for a Mobility Express network is generally completed through the WebUI. Prerequisites
Some 2800 series APs negotiate a block size that the TFTP server does not support, leading to an OACK (Option Acknowledgment) failure. airap2800k9me831500tar upd

While later releases like AireOS 8.10 or Cisco IOS-XE 17.x swell to sizes between 65MB and 600+MB, AIR-AP2800-K9-ME-8-3-150-0.tar remains . This makes it the ideal, lightweight "stepping stone" firmware for a successful transition into Mobility Express when there is insufficient space on the device to flash heavier packages directly. 2.
