Upgrade firmware CW9178I

[HatDauNho]

I have a device: CW9178I.

How can I upgrade via TFTP or USB on the CW9178I, because in the CLI I don’t see TFTP or USB options?

USB does not work like that.  

Is the AP on EWC image, Meraki or IOS?

Hello @HatDauNho,

these new APs are designed for either cloud-managed or controller-based operations only. They do not support the autonomous mode like old legacy APs. So they only work if connected either to the Meraki dashboard or a WLC.

This also means that you cannot upgrade the firmware via TFTP or USB directly on the AP using the CLI because they do not expose CLI commands for direct file-based upgrades like older legacy APs.

All upgrades for these APs are done either via the Meraki dashboard or the WLC.

HTH!

That's not true @Jens Albrecht - they still support CLI download using the archive command when configured for controller (running AP-COS), just like every other AP model:
CW9178I#archive download-sw /no-reload ?
WORD URL of AP image <tftp|sftp|http>://<server_ip>/<file_path>
As you can see TFTP, SFTP and HTTP are all supported for file download.

The upgrade files are still available for download to be used this way - for example:
https://software.cisco.com/download/home/286332769/type/286288051/release/17.18.1

Upgrading via CLI has nothing to do with autonomous mode.
There are many possible reasons for using CLI to upgrade an AP.

EWC is not supported on the CW917x APs.

Good to know. Thanks for pointing this out!
