AirPort shenanigans

Since OS X update 10.5.5 I have been having a few issues with AirPort on my “Black MacBook”.

Namely, AirPort plays up when switching locations.

At worst, AirPort settings are lost for the location I switch to. At best AirPort takes several start/stops to acquire an IP address from a DNS server (no there is nothing wrong with my DNS server). The most common however is, AirPort doesn’t turn ON if it is OFF as part of the location I’m switching from.

I believe Apple have supplied an update in AirPort Extreme Update 2008-004.

However, I’ve only just applied this update so I’m not sure if it has solved my problem. I’ll know tomorrow.

Prior to finding this update (thanks Paul...again) I was tinkering around trying to figure out what was occurring. It all seemed hit-and-miss in the Network Preferences pane so I switch to the terminal. Lo and behold, I found a quick work-around.

ifconfig en1 down

followed by...

ifconfig en1 up

This immediately and without fuss, fixed my AirPort connection. Why this doesn’t do exactly what the GUI does I’m not sure, but there does seem to be some difference.. perhaps that’s part of the problem as resolved in the update?!

This may or may not work for you but give it a shot if you haven’t had time to install the above update, which requires a reboot - There goes my record uptime attempt AGAIN.
