Slow Wi-Fi with Radio Apps?

[bg.nashville]

I just set up a wireless network at home. Everything was working just fine, but all of a sudden I am having a difficult time getting high bitrate streams to load on several radio apps: Wunderradio, Afterhours.fm, and Shoutcast. Problem happen mainly on 96k+ and all 192k+. If I turn off Wi-Fi the streams load quickly.

If I use safari to browse the web the pages are loading much quicker in Wi-Fi than 3G. Anyone have a guess as to the problem and solution?

I am having the same problem here. Tuning in internet radio on 3G is fine, music plays smoothly, but when on wifi, it will stop within a few seconds. Wifi should be faster for sure, there seems to be some problem with the wifi in OS 3.0. Hope Apple will fix it soon.
