While not exclusive to any single ISP, error 651 is commonly reported with certain providers like Verizon FiOS and some cable companies. It's also more frequently seen with specific modem models, suggesting potential firmware or hardware compatibility issues. Checking online forums for your ISP and modem model can reveal common solutions.
