I apologize if this topic has been discussed elsewhere in the forum. Would appreciate it if someone could point me to those previous posts. I am concerned about a new development in my setup. Earlier this week, I switched on my WIFI range extender only to find that it had no juice. So I plugged it to the wall using a standard USB2 cable with wall plug adapter. I expected it to take several hours to charge back from zero. When I went to check, I saw that the indicator lights were on - both of them. The signal indicator light was flashing green, and the power light was a solid green. This, in spite of the fact that the power switch for the range extender was in the OFF position. Puzzled, I disconnected the repeater and turned it on. Powered up okay, or so it seemed. So I put it back in my carrying case, and stowed my gear for the next days' flying. The next morning, I decided to check the repeater again, and flipped on the power switch. It was dead. I plugged it in to a USB2 cable connected to my Mac. The customary orange/yellow charge indicator (the right side LED) was lit. A couple hours later, I examined the repeater. The charge indicator had turned RED. I made sure the power switch was in the OFF position. I reconnected the USB2 cable, and re-established the orange/yellow charge indication. Thirty minutes later, I checked the repeater, only to find both lights on - GREEN, this time, with the WIFI signal indicator flashing, and a solid green on the power indicator. What is the deal with this? If anybody knows, I would appreciate your advice. Otherwise, I wonder if it is time to purchase a replacement WIFI repeater.
