While I'm trying to update the modem, after the selection of the ".bin" file I get the following error: "Error code: 71211
Failed to upload upgrade file. Please select the correct file.".

I've tried with all the firmware listed in the following link:https://www.tp-link.com/in/support/download/archer-mr200/v7/#Firmware

I also tried resetting the modem but that didn't work neither.
How can I solve it?

Thank you
