Time Warner Cable in Wichita Falls. They have a faster tier of service for an extra $10 or $15 per month but I turned that off after the free trial ended. Also, I think speedtest.net may be exaggerating the download speed a bit. I think I'm actually getting around 10Mbps but the test shows higher because Time Warner has a speed boost feature that starts off every download at nearly triple the sustained speed, for a few seconds. That lets smallish files download really fast and makes the connection seem faster than it otherwise would. After a few seconds of the burst speed it drops to around 10Mb/s for the remainder of the dl.
Overall I'm happy with the service, but they do have a bit more downtime than I would have liked. Every month or two the network simply goes down for a while.
And it's expensive. Oh well. At least my area isn't saturated so I almost never see the big slowdowns that people get in over-subscribed cable internet areas. Local DSL is 1/10th the speed at the same price and the new fiber to the door services aren't here yet so there aren't really any decent alternatives.
