Arcadyan KDV21 white screen

@cllnvghn can you help us help you with some clarity? when you say you can’t connect to the gateway, does that mean that when your devices look for the gateway SSID (e.g., myhomenetwork) they can’t see it? Open the T-Mobile Internet app and tap on Network at the bottom of the screen. What does it say? Tap on the SSID Lakeland scroll down the page; is the option “Hidden” turned on? If so, turn it off so you can see your SSID.

Let us know what happens.
