Problems with the Pandora plug-in?

So I now own four Squeezeboxes, all connected to MySB.com Lately, I have noticed that they ALL are having the same problem (even when I disable the sync). I start to play one of my channels, and it will play a couple of songs with a normal time gap in between song (2 ~ 3 seconds). However, by the third song, that gap starts to get longer, and by the fourth or fifth song, the stream will stop. I have to change channels to get it to play again. I do not have this problem playing any other sources on my SqueezeBoxes (including my SiriusXM channels).

Anyone have any ideas? The *only* change that I recently made was to upgrade from 64 to 128 bit WEP passcode on my Wi-Fi Access Point. Thoughts???
