I am in the same boat as Steve, I finished putting together my second ED and after programming the PIC successfully I plugged power into the ED and the green light came on right away which I new was not right. I then tried plugging an ethernet cable into the MAGjack and no lights lit on the MAG jack and there was no connectivity on my switch. I checked the voltage regulators and get 4.99 off the 7805 and 3.35 off the 117v33. The Xtals check out fine at 3.3 on the inputs and 1.67 on pins 4 and 5. I went around the board and retouched everything. I also went around the edge of the Network chip with flux and solder braid and well lests say I won't be doing that again, I did seem to get all the bridges that formed on the one side cleaned up but I am not happy with the results. Needless to say when I plugged the ED back into power I got the same results, Green LED comes on right away and nothing on the MAGjack when plugged into the switch. (Yes the cable and switch are good as my other ED works just fine). Attached are pictures
