If a user is performing the update process of a Tp-link range extender through the manual method, he has to make sure that he kept the downloaded file in an extracted form. The downloaded file in an extracted form provides convenience to users while fetching it during the upload process of the tplinkrepeater.net window. Make sure you have downloaded the correct firmware file on your computer as the incorrect firmware version may corrupt your range extender or may void its warranty permanently.
