Hi

I finally got my Gentoo up and running with XFCE

however my WiFi isnt working.
lspci -l lists the wifi

Code:
01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)


in make menuconfig i added the corresponding option in Device Drivers --> Ethernet --> Wireless

still nothing

right now i downloaded the driver for linux from realtek.
but right now I do not know how to install this driver through the terminal

can somebodz help me how to install an external driver permanently into gentoo??

thx in advance

elomaniak,

Did you set this :?:

CONFIG_RTL8192CE: │
│ │
│ This is the driver for Realtek RTL8192CE/RTL8188CE 802.11n PCIe │
│ wireless network adapters. │
│ │
│ If you choose to build it as a module, it will be called rtl8192ce │
│ │
│ Symbol: RTL8192CE [=n] │
│ Type : tristate │
│ Prompt: Realtek RTL8192CE/RTL8188CE Wireless Network Adapter │
│ Defined at drivers/net/wireless/rtlwifi/Kconfig:1 │
│ Depends on: NETDEVICES [=y] && WLAN [=y] && MAC80211 [=y] && PCI [=y] │
│ Location: │
│ -> Device Drivers │
│ -> Network device support (NETDEVICES [=y]) │
│ -> Wireless LAN (WLAN [=y]) │
│ Selects: FW_LOADER [=y] && RTLWIFI [=n] && RTL8192C_COMMON [=n] │

what are you using to interface with the wireless nic? wpa_supplicant ? wicd ? networkmanager?

also which version of udev are you using?

also have you set rfkill/rf subsystem under networking and selected the standard wireless protocols? in your kernel?

elomaniak,

I see CONFIG_EXTRA_FIRMWARE in the Selects section. Check dmesg if there are any errors related to firmware loading.

Did you set:
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE='your required stuff'
CONFIG_EXTRA_FIRMWARE_DIR='/lib/firmware'
:?:

make sure you have in kernel config

under networking -> wireless -> Common routines for IEEE802.11 drivers selected ..

I just noticed this on one of my own machines and fixed it and the device is now detected and was not without it for the rtl8180 driver
I imagine same issue for rtl8192 perhaps even though it is still in stageing

do you have linux-firmware installed? seems you might need that .. also if you do and it still does not load you can build the firmware into the kernel ..

The support for Realtek cards is not very good, in my opinion. I have a laptop with a RTL8192 and I never managed to get it working properly, no matter how hard I tried. In the best case, the card works for 10 minutes and then I get a kernel panic. So, my advice: get a cheap USB WiFi dongle (look for Ralink chips). These have excellent support and work very reliably in linux.

Well after the emerge of linux-firmware i at least have the wlan0 listed in ifconfig and ifconfig -a

How do i activate it to use it?
I have wicd installed but it doesnt show any reaction when clicking in it

//edit

ok wicd added with rc-update and it starts, but it cant find any wireless network

wicd is a high-level interface, right? It does not need any wifi related
scripts in /etc/init.d/ to be added to the bootup scripts with rc-update,
because it will start anything it needs from there itself. But it still needs
something like wpa_supplicant or iwconfig to handle the lower level
wireless connections between installed wifi network interfaces and
external access points. If using wpa_supplicant, as recommended in
/usr/share/doc/openrc-[version]/net.example.bz2, then wpa_supplicant
still neeeds to be configured in /etc/wpa_supplicant/wpa_supplicant.conf,
even if there is no mention of it or of wlan0 in /etc/conf.d/net and you
did not add /etc/init.d/wpa_supplicant to the boot scripts with rc-update.

You can tell wpa_supplicant what wpa_supplicant wifi driver
you want to use in /etc/conf.d/wpa_supplicant.

edit:
Actually I do not know if that last part is true. Does
wicd use the /etc/init.d/wpa_supplicant script to start
wpa_supplicant? If not, wpa_supplicant might not see
any command line options (like which wpa_supplicant
driver to use) in /etc/conf.d/wpa_supplicant. Wicd itself
might have wpa_supplicant related options in its own
config file where you can specify that.

If you have a wpa security encryption use wpa_supplicant. If not just use wireless-tools (but I prefer wpa since most houses have wpa encryption instead of wep).
Please follow the guide bellow:
