I've flashed it for our WiFi, I even re-downloaded the firmware, and it won't connect to my computer. It and the NXT agree that they're connected, and the white light flashes like it should. I tried one of my NXT bricks, (with the RobotC firmware) and it has the same symptoms. It won't connect at our teams meeting place either, so I highly doubt it's the WiFi. I can connect via USB for testing, so it isn't emergency, but I would like to figure this out ASAP. All the battery's are charged up, too.

When Ernest3.14 comes, he'll help. Personally, I am not yet familiar with the Samantha module. :crying: :crying:

Thanks roboRed. :) Sorry for not responding earlier, but the PSAT was yesterday.

Does your computer connect to the wifi? If so, what did you use to flash the Samantha ("Network Config" or "Competition Network Config")? Sometimes only the latter will work.

Yes, my computer connects fine. I'm using a 2GB flash drive to flash it. It's been working fine, and then it all of a sudden started dropping the connections. Is it possible that there's something wrong with my Samantha Module?

Did you drop it? Is it in any sort of a Faraday cage (metal stuff around it that shields wireless signals)?

I didn't drop the Samantha, and no, there's nothing surrounding it to speak of. I mean, there's a couple beams, but not enough to effect it; it's pretty exposed.

That's really weird. What version of firmware for the Samantha are you using?

I'm not positive. :P How do I find out, and where do I get the latest?

Does it affect anything that the Samantha is mounted so that its right side is closest to the ground? Like, horizontal on its side.

That shouldn't be a problem; lots of teams do that. You can find .hex files for the Samantha firmware in the RobotC program folder (Firmware/Samantha.hex). Take a blank flash drive and only copy that file onto it. And now I bring you Tim Huffman. </ drumroll> http://www.youtube.com/watch?v=hh8YUswtTss

It turns out I needed to re-install the NXT drivers on my computer. I discovered this when I hooked the NXT up to my computer via USB for some testing, and it didn't recognize the NXT. Thanks for all your help though!
