: Confirm the MD5/SHA256 hash of your downloaded file matches Cisco's official release page. Ensure your TFTP server supports large file transfers (blocksize adjustments may be required), or switch to an SFTP/HTTP server for better reliability. Issue 2: AP Stuck in Boot Loop
: After rebooting, the AP broadcasts a "Cisco Air Provision" SSID, allowing you to configure the network through a 10-minute setup wizard in a web browser. Important Deployment Notes
A primary reason network engineers target this exact version is security. Release 8.5.182.0 includes a critical code fix for (colloquially tied to Wi-Fi security flaws). Upgrading to this version mitigates potential Denial of Service (DoS) exploits on the wireless bands. 2. Enhanced Enterprise Integration
