I recently purchased a Mifi 2200 from Radioshack and they also helped set my account up.
The night I purchased it I was using it fine, there were no problems connecting whatsoever. When I finished using it I turned it off and went to bed. But today I turned it on and now it will not access the internet.
I open up 192.168.1.1 and try to connect through there but it just keeps disconnecting. The IP Address, Mask, Gateway, and DNS are all 0s even though I have it set to automatically obtain them. Also at the top it switches between EvDO Rev.0 and EvDO Rev.A and then finally gets stuck on 1xRTT if that is important information. The LED that shows connectivity is a solid green which according to the manual means it is connected but isn't transmitting or receiving data. The device is activated and still has plenty of data usage until the next billing period. I am using it wirelessly. I am also using Windows 7 if that makes a difference.
I've tried ipconfig /release, renew, and flushdns but that about covers my network troubleshooting abilities. I've also tried resetting it to factory defaults but that didn't seem to help either.
If anyone has any clue as to why it worked perfectly fine the first day but not at all now I would really like to know.
Thanks in advance to any and all help.
