Internet download speed supposed to be 300Mbps. Getting less than 50Mbps for the past 28 days.

Comcast Internet is broken.  I have rebooted my Cable modem multiple times (locally and remotely) and have even done a factory reset on the modem.  There is nothing wrong with my internet equipment.  Comcast is throttling my connection at the wrong speed and I can no longer ignore it as it is causing issues with streaming of my online classes.

I have 30 years of IT experience including 17+ years within IT at Google where I taught Linux, Security, and Networking to front line support.  Just letting you know not to worry about getting technical.  ;)
