I have already configured by Raspberry Pi to be a wireless access point using the tutorial here: http://www.daveconroy.com/turn-your-raspberry-pi-into-a-wifi-hotspot-with-edimax-nano-usb-ew-7811un-rtl8188cus-chipset/ I used the Edimax Nano USB EW-7811Un (RTL8188CUS chipset) just as the tutorial did. The tutorial worked fine, and the Raspberry Pi was generating a wifi network by bridging to its ethernet connection. However, I would really like to have the Raspberry Pi be a hotspot for 5 Ghz wifi.
So I purchased the TL-WDN3200 wifi dongle which supports dual band wifi. According to this - http://elinux.org/RPi_USB_Wi-Fi_Adapters - the TL-WDN3200 uses the RT5572 chipset, and there is a "native driver available in Kernel 3.10.36+ (rt2800usb)".
uname -a gives me
Linux raspberrypi 3.12.22+ #691 PREEMPT Wed Jun 18 18:29:58 BST 2014 armv61 GNU/Linux so I assume that my Kernel version should have a native driver. Indeed, when I type
lsmod there is a rt2800usb module listed. Furthermore, when I use
lsusb the wifi dongle is recognized :
Bus 001 Device 005: ID 148f:5572 Ralink Technology, Corp.
The only problem right now that stops the wifi dongle from working is that hostapd refuses to start up. Here is my hostapd.conf file:
interface=wlan0 driver=rtl871xdrv bridge=br0 ssid=test channel=1 wmm_enabled=0 wpa=1 wpa_passphrase=testtest wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP auth_algs=1 macaddr_acl=0
The only thing I could think of is changing the driver to nl80211, but the driver is not recognized by hostapd. I even tried following the instructions to build hostapd from the online documentation but that didn't make hostapd recognize the nl80211 driver.
Is there anything I am missing here? If not, I was wondering whether anyone could recommend a 5Ghz wifi dongle that works out of the box for the Raspberry Pi? Thank you!
