Does DSL Extreme means Extremely slow? or is deceiving advertisement.?

My ISP (DSL EXTREME), says their basic DSL service has speeds up to, 768 kbps/ 368 kbps. My modems show as the maximum speed 224 kbps/128 kbps. But when I test the speed it only runs at 176 kbps the download. There are no problems with the line I had ATT before running al very high speed, I'm in Los Angeles in a centric commercial / residential area. I know no ISP is perfect, ATT had slow periods and down times every night after 9pm. All the speed test were done also with a Linux OS as well as with Windows XP. According to what is known as basic DSL running very slow going at speeds of about 280 kbps, but DSL extreme is just too slow and I fill is just falsely claiming their service is good and cheap. It's probably the cheapest but also the slowest. That's what they mean by Extreme, Extremely Slow.|||I ignore it...lol yes they always steal and lie... you have to pick the service nobody uses... if they all go to dsl you have to go cable modem or wi-fi and if they all go that way you have to go dsl...
