upstream ofdma channels not locked

I did notice downstream light went to green (no DOCSIS 3.1 anymore) last night after my last post. Download speed and upload speed are important factors when choosing the right cable modem for your needs. 20. There should always be at least 1 channel acquired with a DOCSIS 1.1 or 2.0 modem. 21 But with a Netgear CM1100. My internet works fine, and my speed matches my tier (250 Mbps). I checked my modem page on my CM1000 and I'm not seeing any OFDM channels locked. Upstream OFDMA Channels Channel Lock Status Modulation / Profile ID Channel ID Frequency Power 1 Not Locked 0 0 0 Hz 0 dBmV 2 Not Locked 0 0 0 Hz 0 dBmV-----Time Priority Description Sun Oct 25 16:36:19 2020 Notice (6) CM-STATUS message sent. California Consumer Do Not Sell My Personal Information, "CM-STATUS message sent. I was told the Docsis 3.1 frequencies are above 677Mhz. Docsis 3.1 and EuroDOCSIS 3.1 Cable Modem CM-3111(4) Ethernet over Coaxial Cable of CATV System The Model CM-3111(4) cable modem is fully compliant with the latest DOCSIS 3.1 specification as published by CableLabs® and is capable of delivering downstream cable speeds of up to 3.6 Gbps by using 2 Orthogonal Frequency-Division Multiplexing (OFDM) downstream channels … I've had 3 engineers out over the last 6 months. Upstream power is in spec. Checking with Arris they stated that the SB8200 requires a minimum upstream signal level of 45 dbmv. Tech was out once and said the issue was on our end. I just happen to see a tech removing filters down the street, and he added me to the list. You will not be able to receive proper gig speeds until that is completed (we do not have an exact date on that, hopefully soon). Below is the status page from my modem. 3 Agenda . • 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 OFDMA subdivides a channel into smaller frequency allocations called resource units (RUs). … 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. This means your modem found the frequency with which to receive information from the internet. Upload speeds of 35mbps seem fairly consistent. I would expect to see SNR of 43-45dB with a 9-10dB power level. ABSTRACT We propose a scalable support WDM‐based orthogonal frequency division multiple access‐passive optical network uplink transmission system using an injection‐locked Fabry–Perot laser diode (IL‐FP‐LD). The modem indicates 3.1 / blue on the downstream but the upstream is showing 3.0 / green. 16. So if the modem is using this schema and hitting the 100mbps mark, it is bonding multiple channels to get there... at least 4 are in play. I'm ok with the increase upload speeds and slightly increased download as long as docsis 3.1 is in the works. ; The first 2 checked wiring etc which is a fine. I'm seeing ~340 mbps max download speeds when doing a controlled test from my laptop wired directly into the modem. 38 Not Locked QAM256 0 Hz 0.0 dBmV 40.3 dB 0 0: 39 Locked QAM256 417000000 Hz 5.6 dBmV 40.1 dB 0 0: 40 Locked QAM256 423000000 Hz 5.3 dBmV 40.1 dB 0 0: 41 Locked QAM256 435000000 Hz 5.2 dBmV 40.0 dB 0 0: Upstream Bonded Channels: Channel Channel ID Lock Status US Channel Type Frequency Width Power Acquire Downstream Channel 555000000 Hz Locked Connectivity State In Progress Us parameters acquired Boot State In Progress Unknown Security Enabled BPI Downstream Channel Lock Status Not Ready Modulation 256QAM Channel ID 1 Provisioned Rate ---Symbol Rate 41879.195 Ksym/sec Downstream Power -1.0 dBmV SNR 39.0 dB Upstream Channel Once the water had receded, the extent of the damage became clear.
