 Posted: Thu Nov 24, 2022 2:34 am Post subject: iwlwifi loaded but interface not in ifconfig -a |
 |
|
Good evening. I installed Gentoo linux for the first time on my Thinkpad t430 following the handbook guide. The system is working, but wifi is not.
First, I enabled all the required kernel configs with menuconfig:
| Code: |
[*] Networking support --->
[*] Wireless --->
<M> cfg80211 - wireless configuration API
[*] enable powersave by default
<M> Generic IEEE 802.11 Networking Stack (mac80211)
-*- Enable LED triggers
<*> RF switch subsystem support
...
Device Drivers --->
Generic Driver Options --->
-*- Userspace firmware loading support
[*] Include in-kernel firmware blobs in kernel binary
(intel-ucode/06-3a-09) External firmware blobs to build into the kernel binary
(/lib/firmware) Firmware blobs root directory
...
[*] Network device support --->
[*] Wireless LAN --->
<M> Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi)
<M> Intel Wireless WiFi DVM Firmware support
<M> Intel Wireless WiFi MVM Firmware support
|
Second, I emerged sys-kernel/linux-firmware so the card's firmware could be loaded. Then, I compiled the kernel and installed it with an initramfs.
When the system boots, dmesg shows the iwlwifi module is loaded without errors:
| Code: |
#dmesg | grep iwl
[ 11.684042] Loading firmware: iwlwifi-2000-6.ucode
[ 11.689339] iwlwifi 0000:03:00.0: loaded firmware version 18.168.6.1 2000-6.ucode op_mode iwldvm
|
lspci also shows the driver is in use for the card:
| Code: |
#lspci -knn
...
03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 2200 [8086:0891] (rev c4)
Subsystem: Intel Corporation Centrino Wireless-N 2200 BGN [8086:4222]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
|
Nevertheless, it does not appear in /sys/class/net nor in ip addr nor ifconfig -a. It is not disabled in rfkill, which only lists my bluetooth radio. I have read the threads with similar problems on this forum but I am unable to find a solution there. |

You should add USE=dhcpcd iwd networkmanager wifi" to your make.conf and rebuild world (emerge -uND @world).
After, run "sudo rc-update add iwd default && sudo rc-update add NetworkManager default"
And add to /etc/conf.d/net this strings
| Code: |
modules_phy0="iwd"
modules_wlan0="iwd"
iwd_wlan0="phy0"
config_wlan0="dhcp"
|
After reboot select your wireless net into NetworkManager GUI

mikhail17,
Welcome to Gentoo.
It all looks OK but it doesn't work. I need to ask if you are running the kernel you think you are. The command will indicate that.
| Code: | $ uname -a
Linux neddy_static 6.0.0-gentoo #1 SMP PREEMPT_DYNAMIC Mon Oct 3 19:10:46 BST 2022 x86_64 AMD Ryzen 9 5950X 16-Core Processor AuthenticAMD GNU/Linux |
The time/date, here Mon Oct 3 19:10:46 BST 2022 is the build time of the running kernel.
On your system, is that before or after your last kernel rebuild?
If its before, you probably forgot to mount /boot for the kernel install. That correctly installs the kernel to the wrong place.
There are no error messages for that.
