Touch Pro Wifi

[0Gravity]

Hi All,
I am just wondering if there is a way to tell, if my TP is actually using the Wifi connection? The reason I ask is that when I turn on and connect to my home wifi network, I see no diference in the speed at which web pages load!
Do I have to set it up somewhere to use the wifi instead of Spints network?
BTW, b4 anyone asks, when I connect to my home wifi network, the Wireless Lan settings window does show me connected at 54g and the "Ev" at top of screen changes into the Wifi indicator. But the speed just doesnt seem right!

Also, if you go into the Comm Manager and shut off the DATA connection, shouldn't it kill all data transfer from the Sprint network? Because when I do it still shows me the "Ev" Icon at the top of the screen and when I open Opera it still downloads webpages...even though I am not connected to wifi!
IF this is normal, then what does shutting off the "Data Connection" in the Comm Manager actually Do?

Thanks in advance,
