rc1 wrote

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.
