Hi Liz,
Please can you try not using the Browser to configure the Egg, and instead use the Arduino Serial monitor? You can download Arduino at http://arduino.cc/download and access the Serial Monitor from the Tools menu.
I'll also offer you that you can send your Egg back to us for a tech refresh. We'll replace your Wi-Fi hardware with our newer chip-set and re-calibrate your Egg using our improved temperature profiling calibration process as well. If you want to do that, please email support at wickeddevice dot com to arrange an RMA. I'd recommend it, as the new Wi-Fi hardware represents a significant improvement.
