Apple Releases Updated AirPort Firmware and AirPort Utility

Apple has released minor updates to the firmware for the AirPort Extreme Base Station and Time Capsule; the new version is 7.5.2 and works only with the 802.11n base station models released starting in 2007. The base station update improves AirPlay streaming, fixes USB issues for attaching external hard drives or flash drives, and solves some NAT problems.

The most significant change is the removal of the TKIP encryption key type associated with Wi-Fi Protected Access (WPA) from use with 802.11n networking. The certified version of 802.11n should work only with the more secure AES encryption key type.

The update is available after launching AirPort Utility; you may be prompted to install the firmware update, or you can choose AirPort Utility > Check for Updates. The firmware updates also resolve a few minor security issues.

Apple also released AirPort Utility 5.5.2. The latest version fixes a crash, addresses a display issue with DHCP settings, and solves a problem in which the keychain failed to store the network password when a 5 GHz network was named differently than the 2.4 GHz network.

The update finally brings a tiny change to slightly older 802.11n base stations: the capability to add multiple MobileMe accounts for remote access to attached drives and remote configuration via AirPort Utility using Back to My Mac (in AirPort Utility, select a base station, click Manual Setup, click the Advanced button, and then click MobileMe).

Until now, base stations from 2007 and 2008—those from before the dual-simultaneous band models were released in 2009—were limited to a previous firmware release that lacked this feature. Apple told me that they intended to add this feature to the 2007 and 2008 models, but they told me this in 2009. This change may be minor, but it’s great to have all the models running the same release, and getting the same fixes.

I'm curious if you know more about the "fixes USB issues for attaching external hard drives" part. I've kept my AEBS on 7.4.1 because newer versions of the firmware made my external USB hard drive very unreliable. Is that definitively fixed?

I haven't tested this, as I became dubious long ago about such things. Thus, no attached drives at all at present.

I had a nasty problem with some of my AirPort Extremes (not the multi-band version), where after updating the firmware to 7.5.2, I couldn't update the base stations (they would go into limbo & upon restart, they would still be on the old config). We use hardware ACLs, so I need to update them periodically & this was a serious problem. Fortunately, I was able to downgrade the firmware to 7.4.2 & the problem went away.

Oddly, this only afflicted the base stations configured for WEP & 802.11b/g, whereas those configured for WPA2 Personal & 802.11n (b/g compatible) had no problems (long story).
