If it were congestion at the node, then yes. Here, no buffering at all from Netflix, Amazon VOD, or VUDU. Primetime, pre and post, no difference. So I would have to say that TWC is not
doing anything illegal like throttling traffic to major streaming sites. Not sure what Sony network player you are using, but my LG & Panasonic players as well as the laptops and Xbox 360 all have zero difficulty not buffering, let alone being "almost unusable in the evenings". Oh yes, also using Vonage, ipod(s) and 2 other laptops (more than once all at the same time too) with no buffering issue.
Now, I DID have an issue when initially getting Extreme service in that I was still getting buffering issues, and I had slow speed test ratings. Had TWC come out and the idiot tech(s) (yes, morons sent 2) BOTH told me that using wireless I could "never expect the full bandwidth being paid for"
"because it is wireless." So after I kicked them out of my house, I went to Newegg and bought a refurb'd dual band Lynksys (sp?) 3500? I think it is, N router, to replace the 4 year old refurb'd Lynksys single band N router (WRN 160 I think?) and my speeds jumped from up to (yes, I said "up to") 10MBPS to 30+ MBPS via wi-fi/wireless!!!
Moral of the story??? Are you two guys ABSOLUTELY SURE your routers are not the cause? I just state this because it was ultimately my issue here. Hope this might help.
EDIT - Also, just so we are on the same page, the LG is wi-fi built-in and the Panasonic is hard-wired.
Second EDIT - Just now ran speedtest.net and during primetime I am getting 30.16 down/4.87 up, 52ms ping time.
Third EDIT - VUDU speed test; 22820 KBPS down/4812 kbps up...Netflix test does not work, at least from the link provided in post 14062.Edited by Splicer010 - 11/25/12 at 5:58pm
