kern/174722: [wlan] can't use channel 12 and 13 (14) with my wifi interface

[Carsten Wiedmann]

Hi Adrian,

I guess you mean:
ifconfig wlan0 regdomain ETSI
or
ifconfig wlan0 country DE

But this makes no difference. I only have the channels 1-11.

And "ifconfig wlan0" is always showing the correct:
"regdomain ETSI country DE"


Of course, I don't understand why it isn't enough to set "country DE" in "/etc/rc.conf"?


>From "man ifconfig" --> country:
| Set the country code to use in calculating the regulatory con-
| straints for operation.  In particular the set of available chan-
| nels, how the wireless device will operation on the channels, and
	

>From "man regdomain" (The regdomain.xml file):
| This information is used by the ifconfig(8) program to construct regula-
| tory state for download to the system.


And in "/etc/regdomain.xml" I have:
| <rd id="etsi">
|   <name>ETSI</name>
|   <sku>0x30</sku>
|   <netband mode="11b">
|     <band>
|       <freqband ref="F1_2412_2472"/>
|       <maxpower>30</maxpower>
|       <flags>IEEE80211_CHAN_B</flags>
|     </band>
|   </netband>
|   <netband mode="11g">
|     <band>
|       <freqband ref="F1_2412_2472"/>
|       <maxpower>30</maxpower>
|       <flags>IEEE80211_CHAN_G</flags>
|     </band>
|   </netband>
| ...

2412 is channel 1
2472 is channel 13

Regards,
Carsten
