We've tried every combination we can think of- both at&t options, different countries, no isp, etc. I used the connection information from the Sprint software. The logs show nothing other than 3g init- then nothing. I would have expected it to show a failure in the log. When I go to the status page, the 'Connect' button doesn't seem to do anything. It looks like the 3g functionality was really just an after-thought on this device (no documentation or logging). Will 1.30 address any of this and when will it be available? I was really hoping to avoid the Cradlepoint price tag, but I may just not have an option.
