Speed is great to measure, certainly nothing wrong with having it.
For what its worth, on our properly set up and working wi-fi network, we get along fine on TWC/Spectrum 6/1 with an actual measured 7 down and 1.25 up.
Never, ever, any buffering, we do not pay for TV, OTA with superior HD picture then ANY pay TV service, bar none. We use a Channel Master DVR+ for the main TV.
We also have 4 Roku players for streaming and have a subscription to Netflex and Hulu+
Price is $39.99 per month for 6/1 TWC/Spectrum internet plus less then $20 a month for our Netflex and Hulu.
Im only saying this as IF and only if some people are looking to save money, if your network is working properly you can get by on WAY less then some of the speeds I am seeing posted here.
With that said, I suspect soon TWC/Spectrum maybe upgrading our speed at the same price as our Electric Co-op is now laying fiberoptic and offering 100/100 Mbps for $49.00, for the $10 I might get it when it arrives, UNLESS TWC doubles me to 15/2 at no cost.
