[jimmy.wucy]

Hi Sir:

We have same issue with this bug. 
But we have try TFTP and FTP still same issue. 

Our Controller is CT5520. 
AirOS is 8.1.102 
Use service port connect the WebUI and Console. 

Have anyone idea? 

cheers

"Failure while validating the signature" means the file uploaded was corrupt.
Why are you uploading 8.3.132.0 when this version is affected by the KRACK vulnerability.

Hi Leo:

Thanks your information, we will retry new 8.3.133 image.
But we have upgraded other CT5520 use this image(8.3.132) it's OK.
So, we I think maybe this is same bug issue for Tftp and ftp.
Use WebUI the error message like Transfer failure while storing in flash.

#Our TFTP tools use TFTP32 version 4.1 up.

No, the bug affects HTTP transfer. TFTP is the workaround.
