I appreciate the accurate response I get through this forum. I would definitely call them. Acquire Downstream Channel: This should say "Locked", "OK" or similar. Yep. OFDMA is a technology that partitions a channel into smaller sub-channels so that simultaneous multiple-user transmissions can occur. There should always be at least 1 channel acquired with a DOCSIS 1.1 or 2.0 modem. Tried a couple power cycles, then a factory reset. There are also a lot of errors and critical messages. NCP profile failure. NCP) indicates to the DOCSIS 3.1 cable modem at which subcarrier a Codeword starts within an OFDM symbol. Verifying DOCSIS3.1 Upstream OFDMA channel bonding across DOCSIS3.0 ATDMA channels. The CM1150V will only bond (2) upstream channels.

That's how D3.1 works. Online gaming is becoming unplayable. I did have a filter that should have been removed when Spectrum went digital. I have the Netgear CM1150v Docsis 3.1 cable modem telephony and am curious about the downstream channels. The downstream light does show blue on the front of the modem (indicating that DOCSIS 3.1 is being used for downstream). However, I am having an issue with downstream channel bonding. 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). 3 Agenda . I just signed up for Gigablast and I was checking speeds. out of my modem's 32 channels?!? Pretty sure OP should have OFDM channel locked. ; The first 2 checked wiring etc which is a fine. Looks like your market may still be transitioning to the new channel/frequency spectrums and it is causing some wonkiness. I am on the 100Mbps plan and in the Irmo, SC area (not sure if this is why upstream is limited to DOCSIS 3.0). Below is the status page from my modem. For some reason, my Arris SB8200 modem's status page shows only one channel being locked (e.g. Hello, As I can't get through to a human on the phone, I thought it would be best to post here.

Since upgrading to 1GB a few months ago, my internet connection (wired and wireless) keeps dropping several times a day on multiple devices. Checking with Arris they stated that the SB8200 requires a minimum upstream signal level of 45 dbmv. OFDM is locked on mine not on gigablast tier though, 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. Move CM’s service flows back to original BG. The current levels provided by Comcast are 38 - 42 across the 4-upstream channels. By properly … Channel 32 is not locked on. My SNR and power levels are all well within acceptable ranges and I bond to all 4 channels upstream. 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. Brian Cox Support Forum Moderator. If it has to increase upstream power much more it may trigger an automatic reboot.
