Hello. Go to Sprint.com/coverage and type in your exact address. This will show our coverage expectation level as being BEST, GOOD or FAIR. I can see a FAIR coverage area to the NW of Adrian, MI. These errors can be thrown if the device is having trouble determining whether to roam or be on a Sprint tower. Also, 651 and 631 appear to be relating to the same issue which is your dialer for Sprint Smartview maybe corrupt. If you're using Sprint Smartview, you can simply delete these dialers and SSV will create new ones when you click connect again. And no, dialer doesn't mean dial-up speeds. Our USB modems are still cell phones really, just without a screen or keypad. "DUN" (Dial Up Networking) error codes and more information regarding them, I found here. www.modemsite.com/56k/dunserror.asp //
To delete your DUNs from Windows 7, go to your start button, and type in the search bar, either "view network connections," or "manage network connections." This should pop up in the search string above your start menu. Delete 3G, Mobile, and CDMA. If you don't have all 3, delete the dialers you do have. Then try and reconnect from SSV.
To select Sprint Only which disables roaming, in SSV, go to Tools - Settings - Hardware - Modify (3G) - and select Sprint Only in your Roaming section - Apply - Ok.
Hope this helps,

Tom, sorry that I didn't get back to you right away, things just haven't been going my way. I checked the connections , It showed 3, 2 are disabled (local & wireless printers ects.) I deleted Mobile. I reconnected ok.
When I go into SSV Tools>Settings> Hardware> Modify, The selection is grayed out, set at Auto and so I don't for some reason have the option to click "Sprint Only." As I said I've tried reinstalling it , what next ?
