h2. Issue

On desktops and laptops, several WiFi chips don't require non-free firmwares to be loaded.

Several cases exist:

* The WiFi chip doesn't need a firmware, and the driver talks directly to the hardware (ath5k and ath9k compatible chips)

* The WiFi chip has a free software firmware (ath9k_htc, carl1970, and some b43 compatible chips)

On phones, the only WiFi chip that don't requires a non-free firmware that we know of is the OpenMoko FreeRunner wifi chip. The firmware is in a flash chip.
