Recommended USB-Wifi Dongle for OCG-D ?

[Markus Bentz]

Hi,

does someone have experience with USB-Wifi adapters and the OCG-D? I like to add Wifi functionality and make the device a hotspot.

At the moment I’m looking for a suitable USB-Wifi adapter. I tried the Edimax-7811Un which is used in many Raspberry Pi projects. But it seems like the Linux Kernel of the CoreCDP base image doesn’t include the required driver? I tried to cross compile the official Realtek driver without any luck.

Does someone know an adapter that works out of the box with OCG-D using the CoreCDP 2.2.2+ base image?

Thanks

cheers
Markus

Try finding a USB wifi stick based on chipset Atheros AR9271
https://wikidevi.com/wiki/Atheros_AR9271

add this BB recipes
IMAGE_INSTALL += “firmware-atheros-ar9271”

thanks for the recommendation. I compiled a 2.3.3 image with +=”firmware-atheros-ar9271″ and connected a Netgear WNA1100. But it doesn’t seem to work.

# modinfo ath9k_hw
filename:       /lib/modules/2.6.35.14/kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko

depends:        ath
vermagic:       2.6.35.14 preempt mod_unload ARMv5

After plugging in the usb stick i get the following information:

usb 1-2: new full speed USB device using at91_ohci and address 8
usb 1-2: New USB device found, idVendor=0846, idProduct=9030

usb 1-2: Product: WNA1100
usb 1-2: Manufacturer: NETGEAR WNA
usb 1-2: SerialNumber: 12345

If I plug the stick into my Ubuntu machine I get:

[26185.498865] ieee80211 phy0: Atheros AR9271 Rev:1
[26185.511155] Registered led device: ath9k_htc-phy0

[26185.512421] usbcore: registered new interface driver ath9k_htc
[26187.873109] ADDRCONF(NETDEV_UP): wlan0: link is not ready

Is the stick detected as mass storage on my mtcdp?

best regards
Markus

I was not able to get the Netgear WNA1100 to work properly. But I was now able to utilize the Edimax ew7811un. For WIFI connection and as an access point.

You have to compile the driver, wpa-supplicant and hostapd provided from REALTEK (RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip)
