Hummm. I wonder if this will fix the problem that I had when connecting my MBP to internet sharing on my mac mini at my girls house after updating to 10.5.8. I was beginning to think maybe the mini's airport was going out after being on since March 3, 2006.😀 My iPod Touch would connect and get safari, but when the MBP would connect, it would have a self assigned IP and no internet access and even then, the mini's connection would frequently become unstable. I ended up having to just use my backup netgear wireless router. (Which I wouldn't mind if I had the time or patience to set up port forwarding correctly🙄)
