#734: Unable to associate to AP with hidden ESSID on channels 12, 13

When using the SMC SMCWPCI-G 802.11b/g (EU Version) PCI card, it is not
possible to associate to an AP with a hidden ESSID on channels 12 and 13,
even when the ESSID, BSSID and channel were set manually through iwconfig.
This problem does not occur on channels 1 to 11, nor with the Win32
driver.
This card is in regdomain 96 with countrycode 0. Switching to one of the
well-known EU country codes (e.g., 276) is not possible. ''wlanconfig ath0
list chan'' gives the following output:
{{{
Channel 1 : 2412 Mhz 11g Channel 8 : 2447 Mhz 11g
Channel 2 : 2417 Mhz 11g Channel 9 : 2452 Mhz 11g
Channel 3 : 2422 Mhz 11g Channel 10 : 2457 Mhz 11g
Channel 4 : 2427 Mhz 11g Channel 11 : 2462 Mhz 11g
Channel 5 : 2432 Mhz 11g Channel 12 : 2467* Mhz 11g
Channel 6 : 2437 Mhz 11g Channel 13 : 2472* Mhz 11g
Channel 7 : 2442 Mhz 11g Channel 14 : 2484* Mhz 11b
}}}
As far as I see, the asterisk after chan 12, 13 and 14 indicates that the
card thinks it is only allowed to do passive scanning on these
frequencies. Is active scanning necessary to associate to an AP with a
known hidden ESSID?
''wlanconfig ath0 list scan'' gives the following output (even after the
ESSID has been set with iwconfig!):
{{{
SSID BSSID CHAN RATE S:N INT CAPS
0x000000000... 00:0f:b5:5c:d3:7c 13 54M 47:0 100 EPs ATH
}}}
As I said, it works perfectly when the AP is on a channel below 12 and
even continues to work when I change the AP's channel to 13 - the card
correctly follows the AP to the new channel. '''The problem does not occur
with the Win32 driver.'''
Some information from dmesg:
