System: PC Engines ALIX
WLan-Chip: Atheros 5212 (Wistron CM9 miniPCI card)
How to reproduce:
Go to Intrefaces (assign) -> WLANs
Add or Edit your Interface.
Standard: 802.11a
Mode: AP
Channel: Auto or any of the 11a
Error:
802.11a can only be selected if an 802.11a channel is selected too.
Funny thing:
If i select:
Standard: 802.11g
I can select a Channel 11a and it switchs after a reboot to that.
What i expect is:
1 Wlan for 2.4ghz - auto
1 Wlan for 5 ghz - auto
Due to regulations[1] the wlan on 802.11a should be auto in my country (i belive Dynamic frequency selection means that)
