The current levels provided by Comcast are 38 - 42 across the 4-upstream channels. 1 1 Locked SC-QAM Upstream 35000000 Hz 6400000 Hz 47.0 dBmV. ( 21m 50s ) William: Upstream Bonded Channels. Current setup: - Netgear CM500 modem - Google WiFi (1 primary, 2 non-primary points) - Performance Pro Internet plan (200 down / 5 up) - 20+ devices - Speeds are for the most part fine (both on wireless and plugged directly into modem) I am not suffering connectivity issues … The Netgear can bond up to 4 upstream channels, but many Comcast areas are only enabling 3.

Re: Upstream channel 0 Hz not locked If it's just 1 channel that says that, you're probably fine. Downstream is OK Upstream is either very bad or non existent. The modem indicates 3.1 / blue on the downstream but the upstream is showing 3.0 / green. Acceptable Upstream Power Levels (dBmV): Hello, As the subject references, my modem indicates that it is only locking onto one upstream channel. In the Upstream Bonded Channels section, identify the number of Channels, Type, Symbolic Rate to find verify Upstream Power levels are within the acceptable range for each upstream channel. Those 3.0 channels max out around 38mbps throughput each. ... but historically in the 3.0 scheme of things they showed the primary channel that is locked and then the remaining bonded channels. Acceptable Upstream Power Levels (dBmV): When the modem was new, it was always bonded to 4 channels, and it started only bonding to 2 and occasionally bonding to a 3rd every once in awhile but quickly dropping it a month or two ago (Before I threw it into bridge).
