Apple has released version 3.4.2 of the AirPort Extreme driver, which fixes an issue where having more than 1GB of RAM in a Mac or PowerBook with an AirPort Extreme card could result in wireless network slowdowns and disconnects (see reports 1, 2 and 3), especially during periods of heavy network transfers. Previously, the only was removing RAM to bring the installed total under 1 GB.
Apple's release notes state only that the new release provides enhanced networking reliability during certain memory intensive operations, but several readers have confirmed that the new release fixes the >1 GB of RAM connection problems.
Two posters to VersionTracker's comment system note the fix:
- "butcher1" writes: "It appears this update fixed the major problem a lot of users with >1 GB of RAM have been complaining about, where Airport would drop out under extreme network or CPU loads and not connect to a network again until rebooting."
- "Titanium" writes: "I was having some really ugly Airport behavior with my 17" PowerBook with 2G of RAM. Seems to be resolved and working perfectly now."
The new release is a 752KB download available via Software Update. Note that the update will only show up if you have AirPort 3.4 or 3.4.1 software currently installed.
