Update stuck for hours at 0%


Our Piper started an update about 5 hours ago, and hasn’t made it past 0%. It was initially on the wireless network, but just in case that was a problem we moved it to the ethernet network a few hours ago (is it set up to do DHCP by default on the ethernet port?). I recall reading that if you interrupt the update, the SD card can become corrupted. So, what should we do?
