Cellular Disconnected
I have a cellular modem in my Dell Precision 3520. I used it Friday without any problems at all. Today, as I'm at work, I cannot connect to AT&T's cellular network.
When I click the network icon in the system tray, it shows my cellular connection as "AT&T (HSPA)" and then reads "Disconnected" underneath it. It shows 5 bars. If I open network properties and try to troubleshoot the adapter, it gives me a SIM2 error that says I need to enter a PIN code (there is no PIN code on the SIM card, but just for troubleshooting purposes I added one, still got the same error, and then ultimately removed it again).
Things I have tried so far:
- Toggling cellular on/off
- Rebooted computer (several times)
- Uninstalled and reinstalled the driver (twice)
- System restore to the point where it was working the other day
- Ejecting the SIM card and reinserting it
- Verifying that data is turned on with my AT&T count
- Enabling/disabling PIN code
- Resetting network settings via command prompt
- Creating a new APN (with phone, NXTGENPHONE, etc.)
Any tips?
