<p class="MsoNormal">I’m confused by this error message because (1) the NIC is not currently associated or otherwise in use (as far as I know) and (2) the log indicates “num_unused_channels: 1”.<o:p></o:p></p>

<p class="MsoNormal">Is there anything special that I would need to do in order to support a 5 GHz operating channel? This works fine in 2.4 GHz (e.g., reg class 81, channel 1). I would sincerely appreciate any tips!<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:12.0pt">This is based off of hostapd git commit 2b6623ab and using an ath9k-based NIC (Sony UWA-BR100) which is dual-band.<o:p></o:p></span></p>
