I have a Motorola SURFboard SBG6580 Cable Modem/Router combo that was working great until I upgraded my Internet speed with Comcast at which time, they pushed either a firmware or software update that appears to have caused my modem to stop locking channels with Comcast, making it unusable.
The Comcast technician suggested that this was the case given the timing and knowledge that they push updates to cable modems.
I'd like to get the modem working again and wanted to find out if there is a way to remove any software updates or revert the firmware on the modem. I've searched online but haven't found anything helpful. I've reset the modem to factory defaults but that didn't fix the issue.
Any help would be greatly appreciated.
