Download/Upload/Ping seems not correct Fritz!Box 6590 Cable
Into the EVE App I can see my Download & Upload Speed and the ping but everythin isn't correct. Into EVE my Download Speed is 46 MBit/s but the my real Speed is 426 MBit/s. The same with the other two options.

But the the Powerline adapter 1260E works also fine with your plugin. Maybe it's important for your wiki.
