Can you see it on your(Cox) side? Is Spectrum going to fix the Browser Flash player issue? The CM1150V will only bond (2) upstream channels. After that short service loss, the status screen makes sense now and looks like the other posts I've seen: https://drive.google.com/open?id=17VDrhsocpCaSSgRO1UiqNzHpMLq8PR6D. I did notice downstream light went to green (no DOCSIS 3.1 anymore) last night after my last post. There are also a lot of errors and critical messages. Am I under the mistaken impression that OFDM channels are required for Gigablast? • DOCSIS 3.0 Data rate up to 320 Mbps with 8 upstream channel bonding • DOCSIS 3.1 Modulation: Multi-carrier OFDMA BPSK to 4096QAM • DOCSIS 3.1 Data rate Up to 700Mbps with 1 OFDMA 80MHz upstream channels • Frequency: 5-85 MHz • Upstream transmit Signal Level: +11 to 65 dBmV • Output return loss: >6dB NCP) indicates to the DOCSIS 3.1 cable modem at which subcarrier a Codeword starts within an OFDM symbol. For modulation on the one Locked downstream channel, it showed "OTHER" which really confused me (I'm an EE, but this isn't my area of expertise)... Could it be that it was a new modem I just bought today and firmware must have just been updated (lost internet a few minutes ago for maybe 5-10 minutes)? Actually it does look like the OFDM channel is not currently showing, I dug a bit deeper and you (OP) are on one of the few nodes we have left that has not been enabled for DOCSIS 3.1. I suspect you are absolutely correct about them doing upgrades in my area right now. Tech was out once and said the issue was on our end. However, I am having an issue with downstream channel bonding. Tried a couple power cycles, then a factory reset. Acquire Downstream Channel: This should say "Locked", "OK" or similar. OFDMA subdivides a channel into smaller frequency allocations called resource units (RUs). The modem indicates 3.1 / blue on the downstream but the upstream is showing 3.0 / green. out of my modem's 32 channels?!? Online gaming is becoming unplayable.
