AP not visible?

Hi,

I've just finished an installation on my Raspberry Pi model B. I've used the Arch Linux image from the website, installed to an SD card. Everything is working fine except I can't see the wireless AP. I'm using a D-Link DWA-123 WIRELESS N 150 USB which should work out of the box.

Grepping the output of dmesg shows this for the Wifi adapter:

[    4.751308] usb 1-1.2: Product: GO-USB-N150 N Adapter
[    4.762096] usb 1-1.2: Manufacturer: Realtek
[    4.772050] usb 1-1.2: SerialNumber: D8FEE3565D08

Ifconfig shows this:

wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.77.1  netmask 255.255.255.0  broadcast 192.168.77.255

        TX packets 0  bytes 0 (0.0 
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

hostapd.conf looks like this:

[root@alarmpi ~]# cat /opt/piratebox/conf/hostapd.conf
interface=wlan0
driver=nl80211
ssid=PirateBox Share Freely
hw_mode=g
channel=1
auth_algs=1
ieee80211n=1

I've also tried it with this, still no joy:

[root@alarmpi ~]# cat /opt/piratebox/conf/hostapd.conf
interface=wlan0
driver=nl80211
ssid=PirateBox Share Freely
hw_mode=g
channel=1
#auth_algs=1
#ieee80211n=1

Here's the output from dmesg after a reboot:

The eth0 line there is where I manually configured up the onboard LAN. It's successfully broadcasting it's DLNA capabilities via wired ethernet, and I can access the web interface.

However I see no Wifi AP being broadcast, no matter what I do.

Any ideas?

Sorry, should have struggled on a bit more and paid more attention! The clue was in the dmesg output:

[   13.415241] usbcore: registered new interface driver r8188eu

This USB stick doesn't fully work out of the box, and needs the rtl871xdrv driver as detailed on [forum.piratebox.cc]

Once I'd configured hostapd.conf as follows:

[root@alarmpi ~]# cat /opt/piratebox/conf/hostapd.conf
interface=wlan0
driver=rtl871xdrv 
ssid=PirateBox Share Freely
hw_mode=g
channel=1
auth_algs=1
ieee80211n=1

And rebooted it all sprung into life!

Thanks,
TOM

..and you answered your own question before I could get to you. Also, commenting out the driver would have worked too. At least it did for me.

#driver=nl80211
