Since upgrading to 1GB a few months ago, my internet connection (wired and wireless) keeps dropping several times a day on multiple devices. 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). 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). ". Upload speeds of 35mbps seem fairly consistent. 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 Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? My internet works fine, and my speed matches my tier (250 Mbps). There should always be at least 1 channel acquired with a DOCSIS 1.1 or 2.0 modem. Acquire Downstream Channel: This should say "Locked", "OK" or similar. Brian Cox Support Forum Moderator. Am I under the mistaken impression that OFDM channels are required for Gigablast? out of my modem's 32 channels?!? I have the Netgear CM1150v Docsis 3.1 cable modem telephony and am curious about the downstream channels. ; The first 2 checked wiring etc which is a fine. Can you see it on your(Cox) side? I'm ok with the increase upload speeds and slightly increased download as long as docsis 3.1 is in the works. During certain times of the day I'm seeing it much lower. My SNR and power levels are all well within acceptable ranges and I bond to all 4 channels upstream. • 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 Also, I've got a … By properly … Page ... OFDMA 96MHz Channel Cable Modems OFDMA: Low-grant signals are those where less than about half of the subcarriers are active, and the remainder are transmitted as … The CM1150V will only bond (2) upstream channels. • 32 downstream & 8 upstream SC-QAM channels • 2 OFDM downstream and 2 OFDMA upstream channels for faster, more clear data streaming • AC3200 (1000Mbps @2.4GHz with 1024-QAM support + 2200Mbps @5GHz 11ac) † • Simultaneous dual-band WiFi—Tx/Rx 4x4 (2.4GHz) + 4x4 (5GHz) • Beamforming+—Focuses WiFi signals for I would expect to see SNR of 43-45dB with a 9-10dB power level. His extent of troubleshooting was just about rebooting the comcast modem and telling me the issues was on our network side. Is Spectrum going to fix the Browser Flash player issue? Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? I appreciate the accurate response I get through this forum. 3 Agenda . I'm seeing ~340 mbps max download speeds when doing a controlled test from my laptop wired directly into the modem. Since I don’t see any OFDMA channels I’m assuming that’s your DOCSIS 3.0 modem not the CM1200. Generating in-channel and out-of-channel upstream and downstream DOCSIS 3.1 signals. Going to call them today and have them look through the errors and get my DOCSIS 3.1 blue light back. Download speed and upload speed are important factors when choosing the right cable modem for your needs. Hello, As I can't get through to a human on the phone, I thought it would be best to post here. Move CM's service flows to RBG/NB or suspend RF from BG. So basically I have a "24x4" modem router. Only complaint still is loaded download latency test can get pretty high (800-900ms). used?) By subdividing the channel, parallel transmissions of small frames to multiple users happen simultaneously. It looks like you're new here. 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. Learn more about upstream and downstream channels here. The first-release Long Term … 20. Channel 32 is not locked on. Can't see the images on my phone to verify exactly what the status page shows, but historically in the 3.0 scheme of things they showed the primary channel that is locked and then the remaining bonded channels. The upstream channels, however, only half of them lock (channels 1-4). Event Type Code: 1; Chan ID: 15 16; DSID: N/A; MAC Addr: N/A; OFDM/OFDMA Profile ID: N/A.
