...I bought some cheap adapters...
Were you able to find an 802.11g adapter with the mmcx connector? The only one I could find was the Ubiquiti and those run $100+
I guess I could just let a stock antenna stick out, but I'd rather a seamless integration.
No they just stick out the top. It is actually not that bad. I guess it depends what you want to pay for. These cards were $7.95 (AU) each so can't be too fussy. Like I said had to comile a driver for them and play with a few different firmwares but they work. Their range seems to be far less than the standard Aironet one though
Hari's option for debootstrap is a far better option for compiling the drivers.
