Change TP-link power adaptors wireless network password

[tehx]

Hi, I got some Tp-link power line adaptors with wifi off my friend. I want to connect to its wireless network but I don't know the password. How do I change the password for the adapter?

Ask your friend for the password? If he doesn't remember there's usually a way to do a factory reset. Check the manual (or find the manual online if it didn't come with one).
