This is normal. Several have reported speeds on Wifi no faster than on the 3G network. Even when connected through Wifi, all info still goes through the BIS Servers, which slows it down.
Do a search of the forums and you'll find a ton of info on it.
Also, try going into browser options and shutting off Java Script support and change your browser to Hotspot Browser (when connected to wifi). That will speed it up noticeably.
There is a cool Free app here on crackberry you can download called speedtest that you can use to see exactly what your speeds are. It may not be entirely accurate but it can give you an idea of the speed difference from network to Wifi.
There's a difference, but it's not noticeable. The fact that wifi is going through BIS does not really make much of a difference. The BB Browser just plain sucks at rendering css, javascript, etc. That is what really slows it down and hence why you don't see much of a difference on wifi.
I can definitely see a speed difference. I am on wifi most of the time (home and office), so I notice the difference when not on wifi (slower) as opposed to the other way around.
Ok well i dont know if this is related but im connected to my wifi but its greyed out and I cant go on appworld or use bbm... Im roaming and i have data turned off but it used to work on only wifi before but now its not
