What does COX do when they "Upgrade" the download speed to my Internet? Also, I see speed test variations when going to different test locations..could this be the reason users are complaining about not reaching their expected speeds?

Thanks KevinM2 and Cox for the upgrade.  As I posted in another thread, my before and after modem reset went from 180+ to 218 using the Cox Speed test.  Not bad for a wired system.

My original question was what did Cox do to increase the speed.  Was it a hardware tweak or something software related on your end...since nothing change on my side.  What's for the future?

I do see differences in speed test utilities, and some actually concurred with your numbers or even better.  Too bad users are having issues.  Maybe the modem speed procedure that CurtB outlined in the other thread will allow users to view their max Speed of the modem.  This will have a major issue when trying to get > 100Mbps speed test result.
