I have this adapter bought in the Czech Republic, I trying to upgrade firmware current version 1.0.1 Build 20170908 Rel.62477 online upgrade through the web interface say the latest version is 1.0.2 Build 20171016 Rel.61347, but the upgrade is failing. I try to upgrade manually download files from  https://www.tp-link.com/cz/support/download/tl-wpa7510-kit/v1/#Firmware, but when I unpack files there is .bin firmware. Web interface after uploading bin fails with error Failed! Wrong file. When I try to use the windows tpPLC app, I need a GGL file. Where can I download the correct firmware for this device?
