Reduce Latency

Hi,

 

I am trying to reduce my latency while using Spectrum.  I wanted to post my signal strength and ask for any input you might have.  I only have the internet and have no splitter between at the box which then goes directly to the cable modem.  Here is the status page from the SB6190:

Re: Reduce Latency

You want to reduce latency because you're a gamer or use extensive video conferencing? Outside of any physical coax issues causing your problems, the 6190 has a chipset with a fatal flaw that increases latency. I myself have a 6190 and don't notice any problems, but I'm not a gamer.

I am a gamer trying to reduce latency. I have read about the 6190 issues. I wasn't sure if all 6190's were effected by this issue.

Re: Reduce Latency

The Puma 6 chip design flaws get worse as the speed increases from 100 Mbps up to 400 Mbps, which is the maximum for this 24 x 8 modem when used on Spectrum.  But you also have a second severe problem, which is high noise on the signals coming in to the modem.  Look at the high numbers of both corrected and uncorrectible data packet errors on every channel. 

These can be caused by broadcast TV or cellphone signals leaking into the cable system, or by a signal amplifier that is far out of adjustment.  You definitely need to schedule a home service tech to visit and resolve the noise problem.  Swapping out the modem for a different model will do nothing to reduce the noise and the resulting errors.

Thank you for the reply!  I have a tech coming out today and will update.

The SB6190 is a 32x8 modem.

 

Just be aware that if you elect to use the Spectrum supplied modem/gateway it will more than likely also have the Puma6 chipset so you won't do anything to improve latency. I think the Technicolor and Ubee supplied modems do not use Puma6 but the most commonly supplied modems from Arris do.

@reds91185  You are right about the SB6190 modem.  It is capable of 32  channels, but the local cable system only has 24 activated in the modem, and they are all full of noise.
