G4 733 running 10.4.11
This problem has only recently arisen.
Symptoms are that the Airport icon turns grey but retains four bars. Usually no networks are shown in the dropdown menu. Turning Airport off/on has no effect. Sometimes it will return on its own. However sometimes networks are shown in the menu and then connection is usually possible.
It originally started to show itself when the Mac had been in use for some hours and would then mean that Airport would not show any network virtually continuously until shutdown. Now at boot it maybe OK for several hours, a few minutes or not at all. During the day it will sometimes come back for hours or just minutes.
Laptops used in the same room are OK.
No nearby networks are on the same channel. Our router is on automatic channel selection but I have tried all channels to no avail. I have rebooted our router.
I have deleted com.apple.airport.preferences.plist and zapped PRAM.
Booting from two other HDs (10.4.2 and 10.4.11) the same problem appears, which to me suggests the cause is within the G4.
Suggestions welcomed.
Thanks,
Michael
