if your on a router behind the U-verse Gateway. expect loss of speed.. i dont know if the tradiotonal "Bandwith Loss" when you use a Router applies to the U-Verse Residental Gateway. as i only had the service myself for a month before i had to move. (and quite frankly im paying less (67$ a month prorated for phone and Net uncapped w/ WideOpenWest)
but never expect Rated speeds. further away you are from thier distrubtion centers les syou get.. Uverse Is still a DSL product afterall.
