I'm trying to update to the latest firmware, but I'm receiving a message that says "Upgrade unsuccessfully because the version of the upgraded file was incorrect.

Please check the file name." and the error code is 18005.

I've downloaded the firmware from this link: https://www.tp-link.com/ca/support/download/tl-wr940n/v5/#Firmware.

I'm in Canada, but the file provided for Canadian users has "US" in the name. I looked at the US download site, and the files are identical.
