What kind of wireless router are you using? A G or an N? I used to have a G but upgraded to an N & I get loss of connection a lot less now. If all else fails think about getting a N router & see if that helps. Remember to save your receipt in case it doesn't help. My old G router was a Netgear, I used to get booted off occasionally & eventually I couldn't even log on(b/c I live with 2 other people so the connection becomes unstable). Upgraded to a Belkin N wireless router & now the connection is much more stable. Also try checking your settings or moving your wireless router to a different location. Hope you solve your problem. One more thing there could also be some compatibility problems. Maybe the G adapter in the PS3 isn't that compatible with the wireless router you are using(never heard such case though). Similar to pc's.
