I see you got it connecting while I was typing my 2 cents, but I'm posting anyway because I've had that problem and what I've observed and done to fix it.

I could cold boot the modem and the router, but everything other than the CM DVR+ works perfectly.
I could reset the CM, but I think I'll lose all my Series to-do programming. Any ideas?
I've had this happen, but only when I was monkeying around with the WiFi dongle. For example, unplugging the dongle, plugging in Ethernet, and back to WiFi, or unplugging the dongle when playing with updates. To correct the issue, I usually unplug the router and the modem, reboot the router, then the modem, and then Cold Boot the DVR+. Some times that works, and other times it takes a period of time (15 minutes, 1/2 hour), and the DVR+ magically finds the Internet again. No clue why!
I've also had trouble acquiring the Internet when I had the DVR+ only 2 inches from the floor, instead of about 18 inches above the floor which is where it usually sits. While it doesn't have problems getting Rovi data when it's near the floor, it seems to have difficulty acquiring the Internet, even though it finds the router. It doesn't make sense to me, but that's what I've observed, but I haven't ruled out some other cause.
Did the DVR+ or the Router get moved? Did furniture get moved between the Router and the DVR+? Any new electronic devices? Is the microwave running?
A Factory Reset would definitely erase all scheduled recordings, and lot more. It's the last thing I would try, and only after giving the DVR+ time to magically grab the connection!
