|
|
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: |

try changing from wext driver to nl80211. If that doesn't work recompile kernel with:
Quote: | [*] Networking support --->

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?
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. _________________ Defund the FCC. |

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 |
