Speeds being switched at different times of day - uh, no. Either the rep was confused or didn't communicate clearly, but that's just flat-out false. Your DSL connection gets switched when it gets switched. Downstream and upstream are tied together; if you're maxing out your downstream, then that throttles your upstream, and vice-versa (which is why, when you run a speed test, you'll see it test first one, then the other, rather than testing both simultaneously).
DSL being switched at different time than phone - ok, THAT is accurate, although usually both get switched simultaneously, or close to it.
Fusion basically uncaps your speed, so if you were already connected at the max speed possible for your location, you may see little or no change. Your upstream was obviously capped beforehand, and now that it's uncapped you're seeing the obvious increase in speed. It's like driving your car down the freeway, and we take away the speed limit: you can go as fast as your car can with you flooring the gas pedal, but you're still limited to how fast your car physically can run.
Btw, if you're seeing 2.4 on a speed test, that usually means your modem actually IS getting a full 3.0. Up to about 20% of your bandwidth is reserved for routing overhead (see »DSL FAQ
»What is the 80% bandwidth / speed
). That's just how the internet in general works, not anything wrong with your connection specifically.
However, we might be able to tweak the settings to improve the downstream traffic; send me a PM with your account info and I'll have a tech look into this for you.
Second question: if you're getting the Fusion speeds now, I'm sure your phone has been moved over too. Tech can double-check that for you too, if you'd like.
