Spectrum's Loaded Latency problem is horrible and they won't fix it.

Use Fast.com to test your down load and upload speed, as well as, your latency and loaded latency.  Spectrum's loaded latency is absolute garbage.  It's pathetic and it's 100% Spectrums fault.  My loaded latency is around 850ms and this is complete garbage.  I've taken my PC gaming system to other homes and tested it on their ISP networks and the loaded latency is far less.  Spectrum won't fix this problem.  If you're a gamer or intend to stream gaming, I highly recommend not to use Spectrum.

    This isn't generally Spectrum's problem to solve. What you can try is swapping to one of the newer DOCSIS 3.1 modems which have Active Queue Management (a fancy way of saying Quality of Service) that can be applied to the Download and Upload. WIth that said, you're better off setting up QoS on your router. You'll need to set the QoS on your router to a speed under what you get on a Speed Test, so that the latency does not skyrocket when downloading or uploading. Keep in mind that if you have a connection like 400Mbps or 1Gbps, most home routers don't keep up while running QoS. 100Mbps, anything made in the past couple of years should be able to handle it, with 200Mbps cutting things close for lower end routers.


    The reason this is happening is due to the way Spectrum's network operates. Your download and upload is provisioned in at least one location. Your modem, and possibly the CMTS (the router that is generating your Cable Internet signal and also connecting you to Spectrum's Internet backbone). The pipe from the Internet going towards your house is larger than the pipe going to your house. So the bottleneck you see, the high latency when saturating, is because a point before your modem is sending data to your modem faster than it is allowed to transmit to your home. In order to avoid dropping packets (meaning less reliaiblity) or other unintended behavior, network equipment queues up the data for transmission instead of just dropping it. This actually benefits video streaming, because many players see the slightest amount of packet loss or shake in connectivity as an overloaded connection, when then leads to a quality drop.


    Again, the only real fix is to throttle down your download to a speed just under what your connection is rated for, using QoS, or whatever is downloading the data. Steam on PC for example has options built in to throttle back download speeds so you can download while playing games. Or avoid impacting streaming and other activities on the connection.

    It is more of a QoS issue... basically a buffer bloating problem. Simple view of the problem: data is dumped to buffer in a burst, held, then bursted again.

    Cable systems have always struggled with it because of how they function... how connections are metered/bursted. We were less aware of it in the past because the bandwidth was much more constrained even when bursting.

    The trick to managing it better is having a good QoS implementation at the router, or elsewhere in your environment.

    Have demonstrated the difference to people by slingshotting through a 10/00mbps switch before the router... a cheezy way to strong-arm a throttle in hardware.
