I purchased a 3 piece P9 setup back in January. 2 of the 3 units are rock solid and reliable. The 3rd unit goes solid red at least 2 times a day for the last week. When that happens the devices connected to that unit will not reconnect until the device is unplugged. I tried resetting from scratch and it worked for about 2 days and now back to the same problems. I'm really getting frustrated. Please help.
