It looks like you are trying to use a Proxy (10.0.0.60)? The firmware update did take care of the errors that were happening with the modem, so it looks like at this point there is a configuration problem, likely involving those proxy settings.
You can either try to fix those settings, or factory reset the device (which I would recommend) and start fresh. To do this, power off the device, hold the reset button down (you may need a paperclip), then power on the device while continuing to hold down the reset button for about 45 seconds or so. You will see the USR light flash RED and then go solid RED to indicate the processs has completed. At this time, power cycle the device once more. Then run the Wizards and reconfigure the device. Please make a backup WITHOUT selecting the Support Files before resetting the device.
