quote: This software update provides improved AirPort wireless networking software.
New Features
This software includes the latest version of the snow (dual-Ethernet) base station firmware - v4.0.7. Instructions for updating the base station firmware can be found in AirPort Help.
There is a new checkbox in the AirPort tab of the AirPort Admin Utility that allows the base station administrator to enable or disable configuration of the base station over the WAN port.
When enabling Internet Sharing over AirPort (commonly referred to as a Software Base Station) you can enter a quoted or hex-escaped password. This provides compatibility with Windows or other wireless clients that require an Equivalent Network Password.
