Hello. I have been one of the many that was dissapointed with airport having problems (drop outs, low signal etc). So, ive been using this solution since Tiger. Seems that it works fine in leopard too. So, thats what its all about:
1) Download IO80211Family.kext from here.
What this file is actually about? This file contains the settings for airport of the version 10.4.9 (which hadnt any airport problems).
2) Find /System/Library/Extensions/IO80211Family.kext and back it up somewhere in case anything goes wrong.
3) Replace it with the one you downloaded
4) Repair permissions, restart.
I hope this works for you, either way, i wanted to share it
PS: !DONT FORGET TO BACKUP THE ORIGINAL FILE!
