(DWA-556) Atheros AR5008/Master mode

Hello All,

Thank you for viewing this post. I am in need of some help with setting up my Linux Access Point using the D-Link DWA-556 PCIe 802.11b/g/n card.

Here is some relevant information:

lspci|grep "Network controller"

Code:

---

04:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

---

lsmod|grep "ath"

Code:

---

ath9k                296248  0
mac80211              253440  1 ath9k

---

iwconfig

Code:

---

wlan1    IEEE 802.11bgn  ESSID:""
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
          Tx-Power=27 dBm
          Retry min limit:7  RTS thr:off  Fragment thr=2352 B
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0  Missed beacon:0

Code:

---

wlanconfig wifi0 create wlandev wlan1 wlanmode ap
wlanconfig: ioctl: Operation not supported

---

As you can see I do already have the Ath9k drivers installed and I can confirm connection to my existing AP. My problem here is setting this device to "Master"/"AP" mode.

I was had tried current setup with Kernel-2.6.27-7-server, right now I am running most current Kernel-2.6.27-11-generic

I know these drivers should support this card in AP mode however there has got to be something i am overlooking.

*BUMP*

Hmm... Where is the support :( I suppose this has stumped the community also? I have been back and forth to madwifi-project and it confirms these drivers can operate in Master mode (Act as an access point) I could care less for the N speeds, I would like to scratch my existing wifi ap for internal one.

I'm having the same problems, can't get AP mode working on my DWA-556 card. I've tried using madwifi (trunk, v0.9.4), but the NIC won't send out any packets after a client computer connects to it.

According to a page at Linux Wireless hostapd is required for AP mode, but hostapd gives me the following errors when run:

Code:

---

# hostapd -dd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
ctrl_interface_group=0
ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not supported
Could not enable hostapd mode for interface wlan0
hostap driver initialization failed.
wlan0: Unable to setup interface.
Flushing old station entries
Deauthenticate all stations

---

hostapd.conf:

Code:

---

bridge=br0 # eth0 and wlan0 are bridged
interface=wlan0
driver=hostap

ssid="somerouter"

hw_mode=g
channel=7

wpa=3
wpa_psk=xxxxxxxxxxxxxx
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP

logger_syslog=-1
logger_syslog_level=2
logger_stdout=--1

macaddr_acl=0
deny_mac_file=/etc/hostapd/hostapd.deny

eapol_key_index_workaround=0

dump_file=/tmp/hostap

I'm hoping someone can shed some light regarding this, thanks in advance!

I am having the same problem with an Atheros AR5008 Dlink DWA-552. I am beginning to think the ath9k driver does not support master mode. I have used this card in master mode before in g mode with ath_pci so I know it is capable.

Ya, I tried using this driver and adapter with hostap and was unsuccessful, So now I am only attempting to get the adapter to function as an AP, I do not need WPA or Radius auth.

I think wlanconfig is a part of madwifi drivers, and not ath9k. ath9k should work with iw command.

I was able to get mine working again by unloading the ath9k and using ath_pci. It only works in G mode, but at least it works. Mostly everything I did was covered here:

Hi again and thank you for the help.

So far I had placed this on hold, however I retried this time using a svn of the drivers recommended [http://madwifi-project.org/ticket/2232] for my kernel [2.6.27-11-server]. Again I can load the drivers and connect to my wireless AP, here is my second attempt to set this device as an AP using madwifi's
[
root@server:~# iwconfig wlan0 mode Master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
]





MAN iwconfig -- is from where I copied the syntax from.

I have the same issue with my Atheros Wireless card for my Laptop.

AR5007EG - Driver shows under System>Administrator>Hardware Drivers
Support for Atheros 802.11 Wireless LAN cards.

However, when I go to System>Preferences>Network Configuration>Wireless, no connections are listed. So I try to ADD and put in all necessary info, yet my Wireless card still will not work.

This is my second install of Ubuntu. The first time I tried so many things to get the wireless to work, I ended up getting pissed off and started over. I tried madwifi drivers, ndiswrapper etc etc etc. This sure seems like a lot of hoops to jump through just to get wireless networking to work on Ubuntu.

Sorry to hijack, but I thought it better to post in this thread since I am having almost exact same problem rather than starting a new thread.
