The people who develop reliable consistent nationwide marketing schemes win out over the actual capabilities of the technology.
I am left to wonder why AT&T DSL is limited to 6.0Mbps down and 0.5Mbps up when the ADSL2+ standard they use would allow for 24Mbps down and 3.5Mbps up depending on distance from the CO or DSLAM. Why is AT&T DSL saying I can only get 6.0Mbps down and Windstream is saying they can get me 12.0Mbps down? Yes, it might cost 20% more than the AT&T I get now, but they are at least trying to use more of the capability of standard ADSL2+ equipment. AT&T fails to tap into a potential increase in revenue by not offering a better service that is already built into the network they have. All to support a simplistic nationwide advertising campaign.
