Use RTL8192SE wireless card in Gentoo with kernel 3

Although I had solve this problem earlier, I forgot the solution when I built a new system today. The configuration in kernel’s menuconfig is:

1
2
3
4
5
6
7
8
9
10
Symbol: RTL8192SE [=m]
Type  : tristate
Prompt: Realtek RTL8192SE/RTL8191SE PCIe Wireless Network Adapter
Defined at drivers/net/wireless/rtlwifi/Kconfig:13
Depends on: NETDEVICES [=y] && WLAN [=y] && MAC80211 [=m] && EXPERIMENTAL [=y]
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Wireless LAN (WLAN [=y])
Selects: FW_LOADER [=y] && RTLWIFI [=m]

But after reboot, it still not loaded. Via dmesg, it caused by firmware missing. There’s a package named rtl8192se-firmware in portage tree but it is NOT the one we need. What we need to do is to:
# emerge linux-firmware.
After this step, it works. 🙂
