Thanks for the welcome Lylej2k and thanks for the program darren.wlsn1.
Since my post, I found this suggestion buried in another forum: Dial ##778 - 000000, then go to Modem, and change Preferred mode to CDMA only which will supposedly kill any data connectivity with phone. (If that is a waste of time, or worse a harmful change, let me know and I'll switch it back).
After a reset I got a new error. Error 13. Service not activated on the network. However, this time, the Vz data connection did not appear to come back in the "connections" tab. Maybe that is good news?
Sorry about not giving more info in my first post. I was hesitant to make it too long for fear no one would read it!
I have outlook syncing via imap with gmail, I have a weather program but it manually syncs, active sync runs almost immediately via wifi with exchange...in short I have several programs trying to hit the internet on startup. I just need them to go wifi rather than data.
I see where you're going with your question though. Find the program that is trying to update and stop it...at least until wifi can get rolling.
Now that I think about it, It may be that I only get the error when I lose connectivity with wifi, which probably means all those programs I just told you about are still trying to connect and they are causing my problem. That may me the very problem NoData is supposed to fix.
For now, I'm going to call it a night but I'll resume testing tomorrow. I'd like to see if the CDMA change makes any difference, but If the error comes back - which it has randomly done - I'll try the program you suggested and post results.
