  1. I just upgraded my internet speed with Spectrum (formerly know as and still using, Time Warner, in some instances). I went from a Time Warner based download speed of about 75mbps and 6mbps upload speed to what Spectrum claims (and shows via Speedtest.net) to be 400mbps down and 20mbps up BUT ONLY when my PC (Win 10 Pro) is the only device on my LAN and it's directly connected to the bridged Arris Surfboard 6183. When I test with testmy.net going either through the modem or through my Cisco RV042 Gigabit dual WAN router (one WAN connection, rated throughput specified at 687mbps) I get vastly different throughput "estimates." I understand that speed and throughput are different but I want to know what Spectrum and Speedtest.net are doing to show the speed without proportional throughput. I ran Wireshark (TCP IP trace tool) and discovered a couple of differences between the testmy.net trace and Speedtest.net. The Speedtest.net appears to be fully on IPv6 addressing when not going through the router (the router is using a dual stack v4 & v6) and data from Speedtest.net was using a Message Transmission Unit size of 1440 or 1472. I got one test to show a small burst of speed via my router of 1200mbps on Speedtest.net VERY FISHY. Testmy.net consistently gave the same answer regardless (+/- 5%) in either configuration. Can someone more up on this stuff tell me anything about what Spectrum and Speedtest.net are doing?

    can you speed up internet speed?

    can you speed up internet speed?

    I use TWC (which is now Spectrum) and have recently reduced my bandwidth from 300 Mbps to 60 Mbps. The reason is that, after two years of fighting with TWC, I discovered what TWC and Spectrum are doing. I have DirecTV and want to use the video streaming on demand which according to DirecTV requires at least 2 Mbps for HD video. Only one in 10 or so times could I view a program all the way through without getting massive numbers of "video buffering" messages and usually the connection got severed. When Spectrum took over this past Saturday ALL my connections got reduced to about 2 Mbps. I complained. What I discovered is that while I paid for 300 Mbps what they gave me was divided up into logical connections at 2 Mbps. I would have to have about 100 connections to utilize my 300 Mbps. None of them would be sufficient to use DirecTV streaming. Since then I have argued and presented my case and I am now getting my reduced 60 Mbps on some connections but not on connections to DirecTV. I am not however paying for service I cannot possibly use. I suspect all the ISPs are doing bandwidth management on the logical connections so that they don't really have to have the bandwidth you pay for available or maybe they're just punishing the competition (DirecTV).
