 |

I built the kernel manually and included everything pertinent I could find. Here's the .config iwconfig reports "no wireless extensions", and wicd-client shows nothing to connect to when it doesn't simply crash. What should I do?[/url]

from the chroot (unless you have wired connection) | Code: | emerge linux-firmware
emerge pciutils
lspci -k
ifconfig -a
ifconfig |
lspci -k output tells what driver the install media is using. if the wifi interface appears in "ifconfig -a" output the kernel sees the NIC attaches a driver and creates an interface. if the wifi interface appears in "ifconfig" output the interface is being brought up. dhcpcd/dhcp (unleess fixed ip is planned) and wpa_supplicant should be installed, dhcp, dhcpcd, wpa_supplicant, net.<your interface name> should not be in any runlevel. net.lo should be in the boot run level, wicd in default run level
after data is gathered and changes made exit the chroot and reboot installed gentoo. if still unable to configure wicd: | Code: | lspci -k
ifconfig -a
ifconfig
dmesg | grep -i rtl
dmesg | grep -i <your interface name> |

In the gentoo install, I have a wired connection if I put net.eth0 in a runlevel or run /etc/init.d/net.eth0 start ; just having net.lo in a runlevel doesn't do it.

coffeecat ... you're missing sys-kernel/linux-firmware which includes rtl8192cfwU_B.bin

rtl8192cfwU_B.bin is part of linux-firmware, if you tried to | Code: | | emerge linux-firmware |
you may have missed an error message. Run | Code: | | ls -l /lib/firmware/rtlwifi/rtl8192cfwU_B.bin |
to see if it is present, you should see | Quote: | ~ # ls -l /lib/firmware/rtlwifi/rtl8192cfwU_B.bin
-rw-r--r-- 1 root root 14800 Jun 12 14:10 /lib/firmware/rtlwifi/rtl8192cfwU_B.bin |
if you don't, rerun | Code: | | emerge linux-firmware |
and recheck
[have not used wicd in a while, but IIRC, a wicd user uses wicd for wired not net.<wired interface name> and /etc/conf.d/net]
