Hi !
I'm playing with regulatory domain using wireless-testing, iw,
crda and ath5 on Debian. Here are some observations:
1) Debian sucks here (while it's otherwise great!). No
wireless-regdb, wireless-crda packages, not even in
experimental. Maybe I need to add some Ubuntu repository
as "deb-src" to my apt sources.list, apt-get source that
stuff and recompile it manually.
2) I remove CONFIG_WIRELESS_OLD_REGULATORY. Then, after inserting
the card, I see in "iw list":
* 2412 MHz [1] (20.0 dBm)
* 2417 MHz [2] (20.0 dBm)
* 2422 MHz [3] (20.0 dBm)
* 2427 MHz [4] (20.0 dBm)
* 2432 MHz [5] (20.0 dBm)
* 2437 MHz [6] (20.0 dBm)
* 2442 MHz [7] (20.0 dBm)
* 2447 MHz [8] (20.0 dBm)
* 2452 MHz [9] (20.0 dBm)
* 2457 MHz [10] (20.0 dBm)
* 2462 MHz [11] (20.0 dBm)
* 2467 MHz [12] (20.0 dBm) (passive scanning)
* 2472 MHz [13] (20.0 dBm) (passive scanning)
* 2484 MHz [14] (20.0 dBm) (passive scanning)
I'd like to highlight the "passive scanning". Is this info
from the card EEPROM?
3) After "iw reg set DE" (for germany), it's now
2412 MHz [1] (20.0 dBm)
2417 MHz [2] (20.0 dBm)
2422 MHz [3] (20.0 dBm)
2427 MHz [4] (20.0 dBm)
2432 MHz [5] (20.0 dBm)
2437 MHz [6] (20.0 dBm)
2442 MHz [7] (20.0 dBm)
2447 MHz [8] (20.0 dBm)
2452 MHz [9] (20.0 dBm)
2457 MHz [10] (20.0 dBm)
2462 MHz [11] (20.0 dBm)
2467 MHz [12] (20.0 dBm) (passive scanning)
2472 MHz [13] (20.0 dBm) (passive scanning)
2484 MHz [14] (disabled)
Great, CRDA worked obviously: channel 14 has been disabled.
And, as I understand it, CRDA can just limit settings
further, not widening it. Therefore channels 12 and 13
are still marked as "passive scanning".
If I want to get them to "active scanning", would I need to
modify the EEPROM of the card? ath_info says "Reg. Domain:
0x60".
