Getting a max of 4 upstream channels on an 8 channel modem; is this normal?
Today I upgraded to a 24x8 channel DOCSIS 3.0 modem (The Motorola MB7621), from the 16x4 channel modem supplied by Spectrum. Once the modem was activated, it bonded to all 24 downstream channels (yay!), but only 4 upstream channels, out of the 8 available on my modem. Screen shot of the channel statistics attached.
I'm wondering, is 4 upstream channels a limitation of Spectrum's network in Brooklyn, NY, or should I bug tech support about this? My service level is Spectrum Internet Ultra 400/20 if that helps.
