madwifi-ng + dlink 510 [solved]

[rituko_a]

Hi guys, I have a problem here.
This is what I've installed:
[ebuild R ] net-wireless/madwifi-ng-0.0.1531.20060427 USE="-amrr -onoe" 0 kB [1]
[ebuild R ] net-wireless/madwifi-ng-tools-0.0.1531.20060427 0 kB
[ebuild R ] net-wireless/wireless-tools-29_pre10 USE="nls -multicall" 0 kB

When I'm doing 'modprobe ath_pci' (in modules.conf autocreation of device is disabled), I see this:
ath_hal: 0.9.16.16 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413)
wlan: 0.8.4.2 (svn 1531)
ath_rate_sample: 1.2 (svn 1531)
ath_pci: 0.9.4.5 (svn 1531)
ACPI: PCI Interrupt 0000:00:14.0[A] -> Link [LNKD] -> GSI 10 (level, low) -> IRQ 10

wifi0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
wifi0: H/W encryption support: WEP AES AES_CCM TKIP
wifi0: mac 7.8 phy 4.5 radio 5.6
wifi0: Use hw queue 1 for WME_AC_BE traffic

wifi0: Use hw queue 8 for CAB traffic
wifi0: Use hw queue 9 for beacons
wifi0: Atheros 5212: mem=0xe3000000, irq=10

Next: 'wlanconfig ath0 create wlanmode adhoc wlandev wifi0'
Okay, ath0 is created, and we can see it in our 'iwconfig', essid is "", channel is 0, mode is ad-hoc.
Next: oops? It dissappeared...
dmesg:
couldn't load module 'wlan_scan_ap' (-3
unable to load wlan_scan_ap

modprobe wlan_scan_ap

Okay, We cannot see such nasty things in dmesg and seems like everything is okay but ath0 is still appearing\disappearing after few seconds. Just blinking...
I have no idea what I can do with it... :\

00:14.0 Ethernet controller: Atheros Communications, Inc. AR5005G 802.11abg NIC (rev 01)
Subsystem: D-Link System Inc D-Link AirPlus G DWL-G510 Wireless PCI Adapter(rev.B)
Flags: bus master, medium devsel, latency 168, IRQ 10
Memory at e3000000 (32-bit, non-prefetchable) [size=64K]

(c) lspci -v

Solution:
'modprobe wlan_wep' solved my problem. I wonder why it wasn't printed in dmesg.
