Flashed ICS i9020T image onto AT&T I9020XXKI1 baseband phone now intermittent WiFi

Question

I flashed a Nexus S i9020T Android 4.0.3 package image onto my AT&T Nexus S. The flash was a success, but the wi-fi is intermittent. It will come on for a bit, but then lose connectivity. In the top notification bar, the wi-fi icon goes away, but the system says that wi-fi is still on.

Could the wi-fi problem be caused by my not flashing the correct radio image after I flashed the ICS ROM? This warning/error message is showing up in LogCat every 1 second.

Answer 1

As that's the wrong stock image for your phone there's something in it that doesn't work correctly, such as a baseband or radio image that's incorrect.
