Hi. My wireless network was working till I changed some factors in the kernel config and rebuilt the kernel. Now netmorkmanager doesn't show wireless connections. Here is the output of "lspci -v"
Code:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
   Subsystem: Realtek Semiconductor Co., Ltd. Device 8182
   Flags: bus master, fast devsel, latency 0, IRQ 16
   I/O ports at 3000 [size=256]
   Memory at f1100000 (64-bit, non-prefetchable) [size=16K]
   Capabilities: [40] Power Management version 3
   Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
   Capabilities: [70] Express Endpoint, MSI 00
   Capabilities: [100] Advanced Error Reporting
   Capabilities: [140] Virtual Channel
   Capabilities: [160] Device Serial Number 01-91-81-fe-ff-4c-e0-00
   Kernel driver in use: rtl8192ce

08:00.0 Ethernet controller: Atheros Communications Inc. AR8152 v1.1 Fast Ethernet (rev c1)
   Subsystem: Toshiba America Info Systems Device ff1e
   Flags: bus master, fast devsel, latency 0, IRQ 43
   Memory at f1000000 (64-bit, non-prefetchable) [size=256K]
   I/O ports at 2000 [size=128]
   Capabilities: [40] Power Management version 3
   Capabilities: [48] MSI: Enable+ Count=1/1 Maskable- 64bit+

   Capabilities: [100] Advanced Error Reporting
   Capabilities: [180] Device Serial Number ff-a8-a1-b6-00-26-6c-ff
   Kernel driver in use: atl1c

and here is the output of "iwconfig"
Code:

eth0      no wireless extensions.

try changing from wext driver to nl80211. If that doesn't work recompile kernel with:

Ok,after a fresh installation, I have the same problem yet. I have followed any documentation on the wiki with no success. Still "lspci -v" shows the correct driver installed and in use, but networkmanager can not identify the wireless device.

ifconfig -a says there is no interface
lspci -v says there is a device and that it has a ?proper? driver assigned

Code:
emerge hwids linux-firmware
lspci -v
updated the pciids database and firmware, any changes for the wireless NIC?
Code:
modprobe -r rtl8192ce
modprobe rtl8192ce
ifconfig -a
got a wireless interface?
Code:
lspci -nnvk
post result for the wireless nic. Edit menuconfig to:
Quote:
<M> Realtek RTL8192CE/RTL8188CE Wireless Network Adapter
<M> Realtek RTL8192SE/RTL8191SE PCIe Wireless Network Adapter
<M> Realtek RTL8192DE/RTL8188DE PCIe Wireless Network Adapter
recompile and recopy kernel; reboot.

Yes. You are my god man. So I think the problem was lack of linux-firmware or hwids. The former one was not installed because I had installed radeon-ucode instead.
Thanks
