I'm in charge of managing an array of Windows Embedded 7 Standard based PCs (they act just like plain old Windows 7).
The computers have 3G cards as their only means of communication, and are on buses. Right now, the 3G cards are configured in NDIS mode which in theory will maintain the connection automatically and persistently. However, sometimes the 3G link fails and never comes back up.
Can someone help me out here? My basic requirements are
- Internet is available always
- If the connection fails, it is detected and retried
Is RAS/DUN more reliable for this sort of thing than NDIS?
