I have WPA4220 kit (one PLC adaptor, one PLC/WiFi extender).
I updated to latest firmware.
Using web browser, I can log in at http://tplinkplc.net with no problem. The password is unchanged from factory default (admin).
The GUI does NOT ask for userid, only password.
After logging in through browser GUI, I configured WiFi settings and other parameters. Everything works fine:-)
I wish to disable low-power mode, so I downloaded the Mac version of tpPLC utility.
It can see both the adaptor and the extender, and displays excellent PLC connection between the two.
It can use the Settings gear icon to access the settings of the adaptor. No password is requested when I click on the icon of the adaptor.
But the utility cannot access the extender. When I click on extender icon, the utility requests userid and password.
I tried admin/admin. I tried admin/password. I tried admin and empty password.
None of these guesses work.
What is the userid and password to use for accessing the PLC WiFi extender using the tpPLC utility?
