 Posted: Sat Mar 07, 2015 1:48 pm Post subject: wifi help Intel Ultimate-N 6300 AGN |
 |
|
I have just installed Gentoo on a Dell Precision M4600. Now for the longest I did not have a wireless option when I checked ifconfig until I realized I needed to update the:
| Code: | /etc/init.d
ln -s net.lo net.wlp3s0
rc-update add net.wlp3s0 default |
Now WIFI turns on at boot. But in XFCE4 wpa_gui does not see an adapter. so I can not connect with the DWM gui interface. Any ideas how to get this resolved? |

Hi, what says:
Is the correct firmware loaded in the kernel also? Recent kernels need firmware blob to be specified in. Have you installed sys-firmware/iwl6000-ucode? |

CONFIG_FW_LOADER_USER_HELPER_FALLBACK is not recommended to be set to yes - you need it disabled. The right way to use your wifi card is to integrate the path to your firmware ucode file in the kernel and rebuild it. As you have installed the whole package for linux firmware there must be already iwl6000-ucode under directory /lib/firmware. So put the path to this file in the CONFIG_EXTRA_FIRMWARE field in kernel config and also specify the directory for firmware location in CONFIG_EXTRA_FIRMWARE_DIR. My config for Intel Dual Band Wireless AC 7260 looks like this:
| Code: | # Generic Driver Options
#
CONFIG_UEVENT_HELPER=y
CONFIG_UEVENT_HELPER_PATH=""
CONFIG_DEVTMPFS=y
# CONFIG_DEVTMPFS_MOUNT is not set
CONFIG_STANDALONE=y
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FW_LOADER=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="iwlwifi-7260-10.ucode"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
CONFIG_FW_LOADER_USER_HELPER=y
# CONFIG_FW_LOADER_USER_HELPER_FALLBACK is not set
CONFIG_ALLOW_DEV_COREDUMP=y
# CONFIG_DEBUG_DRIVER is not set
# CONFIG_DEBUG_DEVRES is not set
# CONFIG_SYS_HYPERVISOR is not set
# CONFIG_GENERIC_CPU_DEVICES is not set
CONFIG_GENERIC_CPU_AUTOPROBE=y
CONFIG_DMA_SHARED_BUFFER=y
# CONFIG_FENCE_TRACE is not set
|
Good luck! |

Where do you see a file like this? my genkernel makeconfig does not have any of these under Generic Driver Options.
EDIT: Ohhh that is my /usr/src/linux.config . Mine says DO NO EDIT |

So you are using genkernel? Your /usr/src/linux/.config will be changed by genkernel with menuconfig. |

Right, and the closest option I see to what you guys wrote about is:
DEVICE DRIVERS --->
GENERIC DRIVER OPTIONS --->
External firmware bobs to build into the kernel binary > Please enter a string value I guess firmware target.
EDIT: Added information on /lib/firmware
I have all of these potential firmwars for my wifi car in /lib/firmware: iwlwifi-6000-4.ucode , iwlwifi-6000g2a-5.ucode, iwlwifi-6000g2a-6.ucode, iwlwifi-6000g2b-5.ucode, iwlwifi-6000g2b-6.ucode |

What about FW_LOADER_USER_HELPER_FALLBACK as mentioned earlier?
| Code: | Symbol: FW_LOADER_USER_HELPER_FALLBACK [=y]
Type : boolean
Prompt: Fallback user-helper invocation for firmware loading
Location:
-> Device Drivers
(1) -> Generic Driver Options
Defined at drivers/base/Kconfig:154
Depends on: FW_LOADER [=y]
Selects: FW_LOADER_USER_HELPER [=y] |

I have all of these potential firmwars for my wifi car in /lib/firmware: iwlwifi-6000-4.ucode , iwlwifi-6000g2a-5.ucode, iwlwifi-6000g2a-6.ucode, iwlwifi-6000g2b-5.ucode, iwlwifi-6000g2b-6.ucode |
I would look at the output from dmesg command in your previous post
| Code: | ...
[ 9.074964] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-6000-6.ucode failed with error -2
[ 9.074976] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-6000-5.ucode failed with error -2
... |
and choose one of these to enter in CONFIG_EXTRA_FIRMWARE field.
To be on the safe side I would:
| Code: | #emerge -C sys-kernel/linux-firmware
echo "sys-firmware/iwl6000-ucode" >> /etc/portage/package.accept_keywords
echo "sys-firmware/iwl6000-ucode ipw3945" >> /etc/portage/package.license
emerge -av sys-firmware/iwl6000-ucode |
This way you can use the right firmware from /lib/firmware in kernel config.
Good luck! |

OK I did what you said. Now where do I go to CONFIG_EXTRA_FIRMWARE ? Or is that what I just did?
I also have this at the end of the last emerge:
| Code: | *IMPORTANT: 3 config files in '/etc' need updating
*See the CONFIGURATION FILES section of the emerge
*man page to learn how to update config files. |
OK I am going to try to operate the mn page.... lol |

More on the topic: https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi
Now look in /lib/firmware folder - there has to be iwlwifi-6000<version>.ucode. Pick up the most recent numbering if there are more than one and build your kernel.
If your are using genkernel:
| Code: | | #genkernel --menuconfig all |
Then look under 'Device drivers > Generic drivers':
| Code: | [*] Support for uevent helper │ │
│ │ () path to uevent helper │ │
│ │ -*- Maintain a devtmpfs filesystem to mount at /dev │ │
│ │ [ ] Automount devtmpfs at /dev, after the kernel mounted the ro│ │
│ │ [*] Select only drivers that don't need compile-time external fir│ │
│ │ [*] Prevent firmware from being built │ │
│ │ -*- Userspace firmware loading support │ │
│ │ [*] Include in-kernel firmware blobs in kernel binary │ │
│ │ (iwlwifi-7260-10.ucode) External firmware blobs to build into the│ │
│ │ (/lib/firmware) Firmware blobs root directory |
You can see the field 'External firmware blobs to build into the kernel binary' and 'Firmware blobs root directory' - just hit enter and type in the corresponding paths for the ucode file and firmware directory. Mine is for different wifi card but the paths are supposed to be the same for you too. Check the other options to be selected also like the ones above. Exit menuconfig and save the changes, then rebuild your kernel:
| Code: | | #make && make modules_install && make install |
For genkernel it is automatically done with first command. Rebuild modules in the end:
| Quote: | | #emerge @module-rebuild |
Update grub for booting the new kernel:
| Quote: | | #grub2-mkconfig -o /boot/grub/grub.cfg |
Reboot and see if wifi is present and connectable. Check once again output of dmesg for wifi firmware.
Good luck!
P.S. I would wipe the kernel and relevant files for the active kernel in /boot directory before execution of menuconfig as it tends to rebuild incorrectly if there are present kernels with the same numbering.

Thanks, I will try all thus stuff later today. If I get this wifi card up, I will be able to test gentoo and see what I like for the next, non genkernel install.
On your last part, how do I clean the old kernels out of /boot dir? |

Just remove the files related to the working kernel which is to be rebuild.
| Code: | | #rm -v -i /boot/*-3.18.7-gentoo |

If you want all 2098 lines ..... https://bpaste.net/show/24ef1e8a77ee
would this be easier if I had just done normal kernel? I mean crap, I will do another install now if that would help.....

OK UPDATE
I did the | Code: | | rm -v -i /boot/*-3.18.7-gentoo |
and rebooted. Then after trying your steps again it compiled. But still there is no adapter in the wpa supplicant gui. Do I need to set up a wifi config file before it will work?
EDIT: added information....
OK I am also checking the wireless section of the handbook. And for what it is worth, maybe it will help here is my /etc/conf.d/net:
| Code: | # Configure eth0
config_eno1="dhcp"
#wifi Configure
#modules="wpa-supplicant"
modules_wlp3s0=wpa_supplicant"
wpa_supplicant_wlp3s0="Dnl80211"
config_wlp3s0="dhcp" |
I do not seem to have one of these: /etc/wpa_supplicant/wpa_supplicant.conf
Also according to the handbook:
| Quote: | Important
It is necessary to have CONFIG_PACKET enabled in the kernel for wpa_supplicant to work. To see if it is enabled on the current kernel, try:
root #zgrep CONFIG_PACKET /proc/config.gz
root #grep CONFIG_PACKET /usr/src/linux/.config |
root #zgrep CONFIG_PACKET /proc/config.gz =
| Code: | CONFIG_PACKET=y
# CONFIG_PACKET_DIAG is not set
|
same for root #grep CONFIG_PACKET /usr/src/linux/.config
my ifconfig is:
| Code: | eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

Does your firmware now load without errors? | Code: | | $ dmesg | grep -i '0000:03:00.0\|iwlwifi' |
Regarding wpa_supplicant you might find some helpful information in the wiki article. |

OK, just a quick update, as I know all of you want to know....lol. After a little more help from DasGregor, my wifi does start auto on boot. I set it up to connect to my network. And I am now posting this wireless from my gentoo Dell Precision M4600.
wpa_supplicant gui is still messed up. |
