[solved] trouble with wifi

[ligang]

After I upgrade gentoo, wifi doesn't work.
I have upgrade kernel from 3.5.7 to 3.9.0
I used the genkernel all to make boot image

the wireless card is RTL8191SEvB

dmesg shows:
rtl8192se: FW Power Save off (module option)
rtl8192se: Driver for Realtek RTL8192SE/RTL8191SE
Loading firmware rtlwifi/rtl8192sefw.bin

when i start wlan0, the error msg is as fellow:
* Bringing up interface wlan0
* Starting wpa_supplicant on wlan0 ...
ioctl[SIOCSIWMODE]: Operation not supported
ioctl[SIOCGIWRANGE]: Operation not supported

ioctl[SIOCSIWENCODE]: Operation not supported [ ok ]
* Starting wpa_cli on wlan0 ... [ ok ]

* WARNING: net.wlan0 has started, but is inactive

I have google this problem and also search the forum, but there isn't a solution for me..
anyone who know this? thanks

Assuming you have the right kernel config, try using rfkill list and post the output.

If you do not have rfkill, emerge net-wireless/rfkill if you have some kind of internet connection.
