Sanity Check - Downstream Bonded Channel Frequencies and Power Levels
Our cable modem lists Downstream frequencies starting at 213000000 HZ and 4.7 dBmV (screenshot below). As I research the Cox frequency standards I'm seeing other customers listing frequencies in the 700000 Hz range. The majority of references I've found are in that 700 MHz range, with the exception for one customer who had channel frequencies starting at 340000000 Hz. Per my screenshot, are these frequency levels nominal? I.E. are they within the baseline for a stable cable internet connection? If not, should I manually set the starting frequency range to 700000000 Hz? The source issue I was originally investigating was intermittent internet signal drops. Bonus question: Can the aforementioned downstream/upstream frequencies used by the cable internet be adversely effected by external devices using the same band in close proximity to the coaxial line? The disruption source would have to be pulsed/tweaked similar to how specialized RF emitters can destabilize nearby wifi, or bluetooth signals. Cheers,

High Uncorrectables: Cox Moderator Needed
I've been having issues with my Ultimate recently, and think it may be narrowed down to Channel IDs. When reset my cable modem's configuration, it used different channel ID's for my downstream that allowed my Internet to blaze. However, moments later it switched back to the channel IDs that keep giving me issues. Screenshot below. Is a Cox moderator able to access my account, and change my Downstream Frequency? When my cable modem connects to this frequency and upload channel, the high uncorrectables come back into the millions (check account notes). The Downstream Frequency screenshot is attached below.
