Upon upgrading a Sony Vaio (which includes a built-in Sony Ericsson GC75 EDGE / GPRS WWAN cellular modem), I was unable to connect to the internet.I was able to get things running in the mean time while the drivers/programs are being updated and are not yet available. 1. Enabled the SmartWiService, and set it to start automatically. Rebooted. 2. Created a link to the Cingular Connection Manager in the Quick Launch toolbar, and set it to run as administrator. Started the CCM and configured it to use "Optimized EDGE/GPRS value" under advanced networking. (Doing so verified that the CCM could save its settings.) Also told it to connect using "EDGE/GPRS Accelerated", as it had lost this setting. M.
