Remember to load the firmware & run Permissions

Thanks, now I don't feel alone having to
recycle power to AirPort.
AirPortExtreme with a Dr.Bott Omni Antenna has
worked flawlessly with my MacSense xRouter MIH-130 tied into SprintBroadband microwave,
until this AirPort update came along.
I dutifully downloaded and installed the update in 1st my G3 iBook with non-extreme AirPort card, and later in my G4 (no AP card) which is tied by Ethernet cable to the AirPort Extreme Base Station, (and then the xRouter spreads Ethernet to various Printers and such).
Well, I wanted to wait to upload the new Firmware 5.3 until I was on the G4 and thus hardwired to the AirPort base station ...but
I forgot, until last night when the "disappearing network" problem started.
Couldn't figure out why my iBook kept loosing internet access with a strong AP wireless signal indicated, while on the G4 it showed access was up and doing fine hardwired to the Broadband modem. The AirPort Base Station had to be the problem? Unplugged the AP and plugged it back in, and that resolved the problem...until the next episode, and the next...

Then I remembered the yet to be installed firmware and update on the G4.
First the AP update Install, then into the Utilities folder, run AirPort Admin Utility, and the firmware update was typically easy.

No more AP problems since!
However, while I got used to running
Permissions with Disk Utility regularly in Jaguar, since Panther I've become, well ...neglectful. Oops!
This time when I ran it on the iBook, Permissions had to handle an iTunes update, and a bunch of new installs that did not get taken care of at the time. Good grief, there was a steady stream of
thousands upon thousands of corrections...on and on and on. At least I could see some progress as the blue bar crept across my screen. I noticed a lot of
localization files (languages) being corrected, so when Permissions were done I ran
DeLocalizer, which removed several hundred MB of useless language files.
All clean!

Works fine!
