as your kernel is 3.6.11 it appears the firmware being loaded is out of date. suggest an update
other stuff:
from chroot
Code:
emerge rfkill

reboot gentoo
Code:
rfkill list
rfkill unblock all
lspci -k
anything show a block? if so can you unblock it. does lspci -k show the correct driver for wifi?
I would disable default powersaving and enable wireless extensions in the kernel until wireless is up and working.
Quote:
[ ] enable powersave by default
[*] cfg80211 wireless extensions compatibility
nl80211 works better on most of my chipsets but not at all on one.
I would recommend using module vice built in where possible for networking support --> wireless and device drivers --> wireless lan
what do wifi led(s) show??

I have

Code:

03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
   Subsystem: Intel Corporation Centrino Advanced-N 6205 AGN
   Flags: bus master, fast devsel, latency 0, IRQ 42
   Memory at f2400000 (64-bit, non-prefetchable) [size=8K]
   Capabilities: [c8] Power Management version 3
   Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
   Capabilities: [e0] Express Endpoint, MSI 00
   Capabilities: [100] Advanced Error Reporting
   Capabilities: [140] Device Serial Number 08-11-96-ff-ff-c3-f2-e8
   Kernel driver in use: iwlwifi


running on hardened-sources
I use the firmware package

Code:

vunnable ~ # eix iwl6005
[I] sys-firmware/iwl6005-ucode
     Available versions: 
     (0)    (~)17.168.5.3
     (1)    (~)18.168.6.1
     Installed versions:  18.168.6.1(1)(06:04:13 PM 02/16/2013)
     Homepage:            http://intellinuxwireless.org/?p=iwlwifi
     Description:         Intel (R) Wireless WiFi Advanced N 6005 ucode


just the kernel driver (iwlwifi as a module, not a built-in)
and this firmware
plus wpa_supplicant (i do not use wicd, just /etc/conf.d/net and net.wlan0 init script)

this is my /etc/conf.d/net

Code:

# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /usr/share/doc/openrc*/net.example* and save your configuration
# in /etc/conf.d/net (this file :]!).

modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211"


I use hardened-sources 3.7.5 but the kernel config should not be that much different:

http://bpaste.net/show/79567/

all is working perfectly for me here, on both 2.4GHz and 5GHz networks

Boot gentoo, run
Code:
 dmesg | grep -i "iwlwifi 0000:03:00.0: loaded firmware version"
Is the version returned 18.168.6.1? If not
Code:
ls -l /lib/firmware/iwlwifi-6000g2a-6.ucode
Do you have the file and is it dated wihin the last day or two? If not present or old,
Code:
emerge linux-firmware
Run
Code:
lspci -k
Does it show iwlwifi for Modules: and Drivers in use: ? If so, run
Code:
ifconfig -a
is wlan0 listed? If so
Code:
 ifconfig
Is wlan0 listed? If not, run
Code:
ifconfig wlan0 up
ifconfig
If/when wlan0 shows up in ifconfig output,run
Code:
iwlist wlan0 scan
Take note of values of Encryption key: , ESSID: , WPA2 Version 1 , Group Cipher : , Pairwise Ciphers (1) : Authentication Suites (1) : for your access point.
I f you could please specify results at each point using this as a check list.set of problems can be attacked

if iwlist scan works progress has been made and the next set of problems can be attacked.

unless you've enabled the correct WEXT pieces in your kernel config, rebuilt your kernel, reinstalled to /boot, i would not expect scanning to work
in fact, i think iwlist specifically depends on WEXT compatibility, as do other tools

in addition to what donahue has suggested, once you have rebooted into your new kernel, please post the following:

Code:

zcat /proc/config.gz |wgetpaste

Code:

wlan0     Interface doesn't support scanning.


I am using for this output build in iwlwifi but output for using modules is the same.

Code:
# zcat /proc/config.gz |wgetpaste
gzip: /proc/config.gz: No such file or directory
No input read. Nothing to paste. Aborting.


More ideas?

sorry about hijacking the thread... but I have similar problems. It appears that rfkill will block no matter what:

Code:
# rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
# rfkill unblock all
# rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes


I always get the error

Code:
Could not set interface wlp3s0 flags (UP): Operation not possible due to RF-kill

hard blocked -- suggests a manual switch
does the wifi appear in Bios? If so is it enabled?
if a laptop there is often a key or key combination that turns the wifi radio on and off and an led that indicates radio status.
does the wifi interface appear in the output of
Code:
ifconfig -a
If so under what name?
does the wifi interface appear in the output of
Code:
ifconfig

does the wifi interface work with a sysresccd or ubuntu livecd booted? From the livecd, run
Code:
lspci -k
and post the make model and Driver in use: for the wifi.
