Roku light flashes while watching

I noticed that while watching tablo (not sure if it does this with other apps) the roku 2 (the latest one) light on the front will flash fast for about 1 or 2 seconds, then goes back solid…then I get a LPW for about 1 second.

Any idea what the roku is going to make the flashes? It has done this twice in the last 12 hours.

The Roku light flashes while booting up, and when connecting/reconnecting to a network.
It’s probably disconnecting, then reconnecting to your network.

ahh well maybe that will justify my powerline network adapter i’ve been contemplating
