I need to change my password for direct stream How do I do this? The TV,s are not connecting to the Wi-Fi

TVs not connecting to Wi-Fi has nothing to do with your DIRECTV STREAM password. What streaming devices do you have? Has this been an issue in the past? Is the internet connection in the rooms of the TVs good? You can run a speed test at (speedtest.com) to get the upload and download speeds. If they are too low or the internet strength in the rooms of the streaming devices is poor, you will see issues connecting to the Wi-Fi and random dropouts of signal.
