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

best ... khay

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]

I've emerged linux-firmware, /lib/firmware/rtlwifi/rtl8192cfwU_B.bin exists, but I still can't connect.

I rebuilt the kernel with rtl8192ce as a module, and it works now. Thank you!
