WIFI as Access Point

[misi]

I want to use the FIT-PC2 as Access-Point, and run asterisk on it.
I need such model what is runing linux, Atom z530 for media codec transcoding in asterisk,
and wifi to connect wireless ip phones.

There is no such model what i can use as AP without loosing the warranty.

Please provide such a model!!

Currently "fit-PC2 Linux" is very close to my concept about "ip pbx" needs.
From my point of view, the current type of WIFI card (with no "master mode" support) is uselessly eating the power.
For an ip pbx server wifi is not enough reliable. (Rather could welcome a second ethernet interface)

1. I need such fit-pc2 model that i can use wifi as access point, to connect VoIP phones.
2. Or if it is impossible i need a 1.6ghz z530 model (z510 is not enough powerful) without WIFI.

Thanks!
