hey everyone, i just wanted to share my experience with updating to 10.5.2 for some of you that are having issues with the update. last week i updated through software update. no big deal. when my macbook rebooted, my router suddenly stopped broadcasting my wireless network. the only way to make it work was to manually reconfigure it with a non-10.5.2 computer (my girlfriend's macbook), but as soon as i turned my airport back on, BOOM, no more router. clearly this was unusable, so i used time machine to restore to 10.5.1 and everything was fine. but i wasn't satisfied. i downloaded the 10.5.2 combo update from apple.com, made a time machine backup, and started from scratch. i did an erase and install with my 10.5.0 leopard disc, then immediately applied the combo update to 10.5.2. i manually dragged my files back from my time machine backup (except the system folder), and voila, everything works, no wireless problems! now that i did it properly, my OS is running smoother than ever, and i'm having ZERO wireless dropouts (i used to have 4-5 per hour). just wanted to say i'm finally HAPPY.
