Then I try to use rt8192cu driver from wireless-testing GIT repository (last commit is 001354fa8f95219a9bf7acd60937edd5b5c02ab1). I have firmware files installed: root@gms:~# ls -l /lib/firmware/rtlwifi/ -rw-r--r-- 1 root root 13540 Apr 4 14:22 rtl8192cfw.bin -rw-r--r-- 1 root root 16014 Apr 4 14:22 rtl8192cufw.bin -rw-r--r-- 1 root root 20526 Apr 4 14:22 rtl8192defw.bin -rw-r--r-- 1 root root 88856 Apr 4 14:22 rtl8192sefw.bin -rw-r--r-- 1 root root 122328 Apr 4 14:22 rtl8712u.bin Look at lsusb: Bus 001 Device 011: ID 07d1:3303 D-Link System and add an identifiers to detect D-link DWA-131 by simple patch: diff --git a/drivers/net/wireless/rtlwifi/rtl8192cu/sw.c b/drivers/net/wireless/ index 71244a3..cf41fd7 100644 --- a/drivers/net/wireless/rtlwifi/rtl8192cu/sw.c +++ b/drivers/net/wireless/rtlwifi/rtl8192cu/sw.c @@ -296,6 +296,7 @@ static struct usb_device_id rtl8192c_usb_ids[] = { {RTL_USB_DEVICE(0x07aa, 0x0056, rtl92cu_hal_cfg)}, /*ATKK-Gemtek*/ {RTL_USB_DEVICE(0x07b8, 0x8178, rtl92cu_hal_cfg)}, /*Funai -Abocom*/ {RTL_USB_DEVICE(0x07b8, 0x8178, rtl92cu_hal_cfg)}, /*Abocom -Abocom*/ + {RTL_USB_DEVICE(0x07d1, 0x3303, rtl92cu_hal_cfg)}, /*D-Link DWA-131*/ {RTL_USB_DEVICE(0x2001, 0x3307, rtl92cu_hal_cfg)}, /*D-Link-Cameo*/ {RTL_USB_DEVICE(0x2001, 0x3309, rtl92cu_hal_cfg)}, /*D-Link-Alpha*/ {RTL_USB_DEVICE(0x2001, 0x330a, rtl92cu_hal_cfg)}, /*D-Link-Alpha*/ Then, remove staging driver, OFF/On device and adapter plugged into the USB bus: root@gms:~# usb 1-2: new full speed USB device number 2 using at91_ohci Load the driver: root@gms:~# modprobe rtl8192cu rtl8192cu: MAC address: 9a:f4:17:03:4d:61 rtl8192cu: Board Type 0 rtl8192cu: rx_max_size 15360, rx_urb_num 8, in_ep 1 usbcore: registered new interface driver rtl8192cu dmesg says: ... usb 1-2: new full speed USB device number 2 using at91_ohci rtl8192cu: MAC address: 9a:f4:17:03:4d:61 rtl8192cu: Board Type 0 rtl8192cu: rx_max_size 15360, rx_urb_num 8, in_ep 1 ieee80211 phy0: Selected rate control algorithm 'rtl_rc' usbcore: registered new interface driver rtl8192cu ...
