I have an M2, that went through set up without a problem. This was only a few days ago, yesterday I noticed the remote is grayed out in the iphone slingplayer app, and on the desktop slingplayer there is no remote that pops up like it used to after setup. The IR blaster has been in the position as set up when it was working. It is fully connected to the back of the slingbox. The cablebox is a Comcast Xfinity, during set-up it was not switched to IR settings - only when I noticed the problem did we go through the steps to switch from RF to IR, but still no remote. Any suggestions on what to do? Will I really need to go through setup again?
I would recommend reconfiguring your input. It is basically going through the step in setup where you'd pick your remote control. Not sure what happened, but looks like your previous remote configuration may have been wiped out. On your Desktop, you can go to Settings > Reconfigure Input to initiate this.
