Do the pods have a short lifespan? I've had mine (6 throughout the house) for a little over a year. Up until the last week, they worked seamlessly, and now, most of them are sporadically disconnecting, requiring a reset (unplug) daily. Nothing has changed, they're in the same locations as always. I've reset the router multiple times, I've "removed" pods and added them back, but all of these attempts result in temporary fix, and then within a few hours, the cycle starts all over again. Given the cost of these, I would expect them to work successfully for more than one year, but wondering if anyone else has experienced this and what the solution is. I'd like XFinity to replace them, as they seem defective, but I don't anticipate Xfinity would accommodate that.
