Just an FYI, the PS3's WiFi NIC is crap. If at all possible get it wired to your router.
If you haven't changed any of the settings from the defaults, then you'll need to set the max bandwidth (start with 15 if anything is wireless) and probably reduce the video quality as well. Both settings are located under the Transcoding Settings (tab) -> Common Transcode Settings (left menu).
