Knoxville TN area Comcast Speed drop is getting worse. Just after Comcast bumped everyone up in speed? Example, Sunday morning 8/2 download speed at 22.1 Mbps, late evening .62 Yes, .62 what the heck is that? Has been bad for over a year now but this is ridiculous. Spending hours on the phone with Comcast. System reset locking up. Something is definitely wrong and no not with the home equipment. Hey comcast, why not some type of end of cable run periodic quality line test? Customer since 2006, cable being replaced about every 4 years. So probably time again!
