Hi Jamie,
If you put a jumper between the 3.3V pad and the ERASE pad then you have erased your Netduino's firmware completely.
When the Netduino Plus has been erased completed, its power (white), user (blue), and ethernet activity (green) LEDs will all come on and stay on--consistent with what you're seeing.
You'll need to reflash your Netduino Plus (first the bootloader using Atmel SAM-BA, possibly on a 32-bit Windows machine...and then the .NET MF firmware).
What version of Windows are you running? 32-bit or 64-bit?
Chris
If you did erase the netduino, then you'll need to use SAM-BA like Chris said.
Here is a good post to check out: http://forums.netdui...p__347#entry347
Today LED's, tomorrow, the world!!! Well, OK, maybe servos.

By chance, does anyone know of any good sources for WiFly troubleshooting? I've looked a bit on here, and the problem I'm having is getting to Write the SPR and initializing.
WriteRegister(Register.SPR, 0x55); if(ReadRegister(Register.SPR) != 0x55) throw new Exception("Failed to init SPI<->UART chip");
Mine keeps failing at this part. Does anyone know a good way to use the terminal with just USB? Do I have to get a USB to RS232 adapter?

That is very strange! The Reset-button on the WiFly shield (at least the one I have; marked with 6/15/10 on the back) just links Gnd to the Reset-pin. I used this a couple of times without problems.Actually what was causing the problems was the WiFly board that I have. At one time I pressed the reset button the WiFly board and it put the Netduino in a strange state. When I put the WiFly board back on and pushed the rest button again, all of a sudden the device was recognized by Windows.
