i have 2.4 and 5, the thing is not about the maximum speed, in fact downloads run fine but streaming and live play is what glitches and I get lags, I can't watch anything on twitch without interruptions every 5-10 seconds and loading bar ... in games it's worse, CS:GO is a noGO, and league of legends is mostly one minute of playtime normal ... 5 seconds lag, umm what else have I tried, Diablo runs ok i guess. In theory my internet runs ok but in practice not that much. If you have other means of testing out wi-fi connectivity, please share and I will try them out in order to give you a more detailed explanation on how exactly my internet sucks major balls and they charge me money for it.
