He said he was probably getting DSL. DSL doesn’t do well streaming IMO. In fact I dropped Netflix because the quality wasn’t that good.
I can download High Def with DSL and play it fine.
With DSL it depends on how close to the switching station you are. If you are within 1 to 2 miles it is fine. After that, the speed tends to drop off. Also, it depends on the condition of the lines coming into your house ( and if your ISP throttles ). I'm within 2 miles and have an average of 20Mbps download ( which is the speed I am paying for ) and can stream HD perfectly.
