I have a Blackberry Storm 9530 and Thinkpad running Windows 7 Pro and Desktop Manager v. 220.127.116.11 (the latest). I have set up a tethered network on the laptop using the Blackberry as a modem and it works well. I would like to set up untethered network using Bluetooth. I have proper connection and linked device (when the phone rings, I can answer it on my laptop), but if I try to access the internet, I get a Code 28. Device manager has a yellow bang on Bluetooth Peripheral Device under Other Devices, and diagnostic says no drivers are installed (Code 28). I know I have to have Desktop Manager running for tethered connection in order to load drivers, but this does not work for Bluetooth. I don't know which drivers I need to install to get rid of Code 28. Can anyone help?
