@cold_river

Make sure that you're suing the correct FW release (device region and HW version should be confirmed).

Here's a guide on how to determine these details - usually from the bottom sticker of your device.

Here's a guide on how to upgrade the wireless router FW.

If this was helpful click once on the arrow pointing upward. If this solves your issue, click once the star to mark it as a "Recommended Solution".

@terziyski I'm using the TP-Link India site and when I select HW version v4, the site shows me FW for Archer C20(EU).

I don't see a Archer C20 FW available on the site.

However, I have another router which is Archer C20 (EU) version but that says "you got wrong file" and won't take the FW either.
