Hello all, I'm not sure if this is a problem that only I am having, but as the title says, ever since my update to 10.5.7 earlier today, my MacBook wireless range has been significantly reduced. I used to be able to sit in my TV room with full signal strength. Now I can't connect at all and have to be pretty much in the same room as the wireless router to connect. Using iStumbler, the signal is down to 22% while sitting in the TV room. Previously, at it's weakest, it got no lower than the mid-70's (percent-wise). Prior to the update I had some off and on problems with it dropping connections, but I was always able to get it to connect eventually. The update to 10.5.7 was in hopes of fixing that, but it looks like it's only made things much, much worse. Really the only thing I've tried thus far is deleting the com.apple.airport.airportutility.plist file and rebooting. No luck. Thanks for any help or advice you can give.
