EAP 245 Can't update firmware
I have a TPLink EAP 245 v3 wtih firmware v 5.0.1 Build 20210113 Rel. 63140(4a50).
Whenever I attempt to update the firmware I get the message "Bad file" or "Failed to check for new update".
I've tried this with firmware files from the US, UK and CA TPLink sites. What can I do to troubleshoot this? Is there a way to force a firmware update via SSH?
Thanks for your help.
