Dynamic Range Window Violation
Hello, I am having issues getting someone to help fix a problem with my internet connection. I receive a Dynamic Range Window Violation in my modem log every few minutes and this greatly affects my internet staying connected and VERY SLOW speeds. I have Cox Gigablast 940MB and speeds are near 50 to 60MB constantly and dropped connection. Modem is brand new and worked find until we switched from 300MB plan to 940MB plan. Here is my error log details from modem event log. This problem has been reported many times and it appears that a "data tech" can be sent to the home to investigate the issue and fix the problem. Please help! Event Log The table below contains the log of events that the SB8200 has detected. This log can be important to the service provider to help diagnose and correct problems, if any should occur.
