Re: [Cable HSI] Channel Bonding

You are losing channel bonding because you're signal noise ratio is too low. Swapping the modem is not the cause of your issue. You need a tech out to your house to fix the issue.

I have not lost bonding since my last post. The SNR (although lower then I like) is well within the modem's range. The lowest reading has been 33.5dB. The SNR went down when they fixed the huge gain tilt on video signals from low to high frequencies. The tilt compensation that lowers lower frequencies must cause some loss in the cable modem frequencies (which for me have always been low frequencies.) You can see that I still have lots of signal strength on these frequencies > 2dBm.

256 QAM: 30 dB minimum. 33 dB or higher recommended. (often used in downstream channels)

It's great to hear that you have not lost channel bonding for awhile now.
