ok, i've attached the alfa and run rfkill list but it shows that there are no blocked devices, then i run modprobe rtl8192cu and strangely the alfa has lighted, but it doesn't work.. i've done dmesg and seen this: [ 1218.079638] rtlwifi: reg 0xc80, usbctrl_vendorreq TimeOut! status:0xfffffff4 value=0xed545b78 [ 1218.079645] xhci_hcd 0000:05:00.0: ERROR no room on ep ring [ 1218.079650] rtlwifi: reg 0xc80, usbctrl_vendorreq TimeOut! status:0xfffffff4 value=0xed545b78 [ 1218.079657] xhci_hcd 0000:05:00.0: ERROR no room on ep ring [ 1218.079664] xhci_hcd 0000:05:00.0: ERROR no room on ep ring [ 1218.079669] rtlwifi: reg 0xc4c, usbctrl_vendorreq TimeOut! status:0xfffffff4 value=0xed545b78 [ 1218.079676] xhci_hcd 0000:05:00.0: ERROR no room on ep ring [ 1218.079682] xhci_hcd 0000:05:00.0: ERROR no room on ep ring [ 1218.079687] rtlwifi: reg 0xc94, usbctrl_vendorreq TimeOut! status:0xfffffff4 value=0xed545b78 [ 1218.241190] ADDRCONF(NETDEV_UP): wlan1: link is not ready for the firmware i don't know how to update it, i'm using ubuntu 11.04 natty with 3.1.0-0301rc9-generic where can i download updated firmware to test it for this card? thx -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
