Hi All,

      I am not able to reload in Access Point and upgrade it to LAP.When ever I do that ,I receive  error "magic number mismatch". My image upload is successful everytime but not able to reload that image.Please suggest me what I have to do for this.Is this due to tftp server ?Should I change tftp server ?

Good morning

Thanks for using our forum

Hi Atit, my name is Johnnatan and I am part of the Small business Support community. You can download the image again from Cisco.com, probably an error ocurred inthe .zip file, it´s would be very useful if  you provide us your device model and software version.

I hope you find this answer useful,
