I was streaming on my 3400X last night when my router at home rebooted. Ever since then the Roku splash screen will display, just says Roku across the screen and the Roku backround tune will playl and then no signal displays on the screen and then it will do the same thing over and over. all my other wifi devices are connecting to my router. The light on the Roku comes on for awhile and then will blink and then go through the same process over and over again. This is a jvc tv with a HDMI-MHL port that the Roku is plugged into.
