@woozle I don't remember which firmware I used. It's a long time that has happened. The adapter works only with ethernet. The web browser interface doesn't exist anymore. Only one old Powerline app...

After Firmware Upgrade, I lost access to web interface of my TL-WPA8630. Using tpPLC the adapter has lost Wifi icon and is seen upgradable only using NVM and PIB files. Online I found only bin files....
