My Stick+ works great upon setting up. wifi connection is great (my wifi works great with the multiple devices currently connected to it). i connect to my Roku account, activate Netflix, etc. once i'm done watching something, i power down my TV with the Roku remote - works fine. once i return and turn on the TV Roku screen appears, i select Home button and upper right hand notification says "no connection." sure enough, connection to wifi needs to be set up again. i've tried all of the suggestions on Roku's troubleshooting pages. tired factory reset. even returned original Stick+, i'm now on my second one. still loses wifi connection between power cycling.
