Here is a possible solution proposed by another forum user, attemptress: One suggestion: If you keep getting failed downloads, you may want to be sure you've set your wi-fi not to shut off when the device is plugged in (otherwise, it may turn-off when the device "sleeps"). To do this, go to network settings, then press the menu button. A two-button menu will pop-up. Press "advanced". Press "Wi-Fi sleep policy" at the top of the screen. Select either "Never" or "Never when plugged in." Also, a couple of other posts recommend you disable screen saver. I'm getting my PE today and I'm on the edge of my seat (I plan on upgrading to Ermine, maybe) so please let me know how it goes.
