100/20 upload speed keeps getting cut by 50-75%
I previously started a thread reporting that upload bandwidth was reduced by at least 50%
Comcast reset the modem and the correct # of upload channels were restored. This lasted for 2-3 weeks. The bandwidth was cut in half again.
After experimenting, I've discovered that if I disconnect the modem for at least 10-15 seconds, when it reboots, it reacquires the correct number of upload channels. Unfortunately, this doesn't last more than 24-48 hours and I lose upload bandwidth again.
Since this process started, I attached a line monitor and noticed that on Thursdays and Fridays, the modem is sometimes unresponsive. After the unresponsive episode, the upload channels tend to drop down from 3 to 2.
