Just fyi that I have successfully upgraded the AP7522E access point from Wing Express 5.8.4 to 5.8.6 by directly connecting the AP to my pc.
It seems that there's some security setup or disturbance in accessing the upgrade image to the "live" access point when I tried it earlier within the customer network.

Can you reproduce this issue outside your clients site? Or useing FTP?

Hello Manuel,

When you say TFTF I would assume you mean TFTP? Please confirm.

If this is the case I would suggest you start by making sure that all firewalls are off on the computer/server on which the TFTP server is installed.

Try out another TFTP server such as TFTPD32/64.

Worst case, please use FTP to circumvent any firewall issues.

Regards,

Chris
