Can I upgrade my airport to a N model?

I've a mac mini mid 2007 (A1176) which doesn't support wireless n, would it be possible to replace the internal card with a wireless n card from a newer mini? I found the post here Can I upgrade from Wireless G to N? but the link is broken and the quickertech.com website doesn't have any wireless cards for mac minis only for mac pros/mac books

Answer this question I have this problem too

Is this a good question?

I did this AirPort-N mod on my mid 2007 Mac mini.

I bought an Atheros AR9280 from Amazon.de Marketplace

The actual reseller goes by the name SC-Computerecke (or Salcar GmbH) on Amazon.de

FYI : the Atheros AR9280 is recognized as an original AirPort-N card by OSX.

Yes and No...

...since the speed of WiFi-N is higher than with WiFi-G, and the range/radius is longer, reception is notably better...

but... you will still have 'dead spots' in your reception...

...so if you have reception problems, you should first try moving your WiFi-reception antenna (i.e. your entire Mac normally) around a few inches...

if you want more in-depth info on the exact location of the 'dead spots' in your WiFi-network, try this software :

The Atheros AR9280 was seen as a genuine AirPort-card by OSX...

...in 10.6 Snow Leopard

...and in 10.7 Lion it could even do AirDrop...

...until 10.7.3 that is...

10.7.3 for some mysterious reason lost it's ability to detect the AR9280 at all...

...the AirPort-icon in the menubar is blank, and it lists "no compatible hardware"...

Oddly, when restarting the Mac mini in 'Rescue mode' (pressing Apple(CMD)+R during startup), AirPort instantly connects using that same AR9280 card... ???!!

...but that doesn't last if you start up 10.7.3 the normal way.

So... after a lot of fiddling around I found the solution is quite easy :

1- reinstall the IO8211Family.kext from 10.6 Snow Leopard and reboot

if you only need WiFi-connection, that will do, but...

...if you also want to use AirDrop, you need to do step 2 also :

2- only after doing step 1, you will be able to successfully reinstall the IO8211Family.kext from 10.7.2 (the previous version of Lion)

It is mind boggling why this works (but it does) because :

- directly reinstalling the IO8211Family.kext from 10.7.2 onto the version in 10.7.3 doesn't work - for some reason you need to downgrade to the Snow Leopard version first...

- the IO8211.kext from 10.7.3 appears to be exactly the same as the one from 10.7.2 ; they have the same version number (4.1.2) and have been created and modified at the exact same date...

You might want to use the special .kext-installer ; you can find it here :
