In the last 2-3 weeks, my two Streaming Stick 4Ks have stopped holding their wi-fi connection. I had to repeatedly reset the devices every time I tried to use them. My Roku Express 4k+ on a third TV continues to work as it always did, and no other devices in the house are having issues staying connected to the wi-fi system. I have had to stop using the Streaming Stick 4Ks since they suddenly became defective in their wi-fi connectivity after having previously worked properly since I installed them a year or two ago.
