<question id="support-broadcom">
<para>Is there a native driver for the Broadcom 43xx cards?</para>
</question>
<answer>
<para>No, and there is not likely to be.</para>
<para>Broadcom refuses to publically release programming
information for their wireless chipsets, most likely because
they use software controlled radios. In order to get FCC type
acceptance for their parts, they have to ensure that users
cannot arbitrarily set things like operating frequencies,
modulation parameters and power output. But without knowing
how to program the chipsets, it is nearly impossible to write
a driver.</para>
