Thank you for your post Freddy.
Note that since these wireless adapters should be installed by the laptop manufacturer only, there is no integration support or documentation publicly available.
The only two Intel® wireless adapters designed for the end user install are:
Intel® Centrino® Advanced-N 6205 for Desktop (part no: 62205ANHMWDTX1):
Intel® Centrino® Advanced-N 2200 for Desktop (part no: 2200BNHMWDTX1):
Both of the above mentioned are PCIe x1 based, and already include the antennas.
I hope this helps.
Unfortunately that's not very helpful. I looked for both of those adapters prior but no one seems to stock them in Australia, furthermore the desktop we are interested in (an ultra-small form factor) only has a mini PCI-e expansion slot.
Fingers crossed someone can answer my question :/
