Thank you for your help. Even your post indicates that the range extender still functions when the lights are off. Mine has an on/off switch on the side for the LED’s.Thanks, again.

Model : Hardware Version : Firmware Version : ISP : I just purchased a TP-Link AC 1750 Extender and a.m. wondering if it is o.k. to turn the LED lights off and still leave it on?Just wondering....
