FWIW.... In my Lantana my wifi was so weak on the Lanai that it was about useless. I went to Best Buy and bought an extender, plugged it in by the sliders close to the Lanai and have full bars on the Lanai now. NO issues. The modem/router is in the front room. The electric outlets could care less the device is one whatever circuit. It works by taking the weak signal and boosting it using two antenna. One brings the signal in and one sends it out. Easy Peazy...
