Wireless LAN Controller Upgrade

[vnirmal112]

Hi,

I was trying to upgrade Cisco 4402 Wireless LAN Controller from 4.0.171.0 to 4.0.206.0.

I was able to upgrade one of WLC without any issues.When i tried to upgrade another WLC, i was getting an error " Failure with Signature Verification".

Can any one help me in fixing this issue and ensure successful upgrade of my device.

Regards,

Nirmal.

Hi Nirmal,

Is the second controller also running 4.0.171.0. Can you download image again from CCO website and try upgrade again.
