CM1150V modem frequent and long reconnects more recently - upstream channel issue.
Hi, I found this forum somewhat helpful and and going to post my experience troubleshooting a problem with the CM1150V. I have not found root cause, but seem to have resolved it for now swapping ou...
Did you ever find a solution for this? I also have CM1150v with seemingly identical issues that are only temporarily addressed by power cycling the CM1150v or using the rented XB7. With the XB7, I still have intermittent high latency issues and some bandwidth loss, but never so bad that it requires a power cycle. There are other posts here that mention that when the upstream signal of the 1150v reaches 48 dBmV that bandwidth drops.
I have a comcast tech scheduled to checkout my line tomorrow, at my own expense.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
