[BUG] [AVM FritzBox 7412] WLAN missing

sliman · September 18, 2021, 4:08pm

Hello Devlops.

I installed today the current OpenWrt-Release on my FritzBox. The WLAN-Adapter will not work and its not documented as known unsupported feature. The reason to install OpenWrt was to make the device to an free Access-Point. Any help for the problem?

Thanks regards.

If u need any data, ask me and I will give U.

Try
echo 1 > /sys/bus/pci/rescan
https://bugs.openwrt.org/index.php?do=details&task_id=3906

sliman · September 18, 2021, 6:07pm

UPDATE:

Sorry, the "echo 1" dont work.

A reinstall also not work, I tried it for safe, cause I played around alot in the web-interface.

Is there a way to list PCI-Devices, the kernel recognize?

Mijzelf · September 18, 2021, 8:19pm

lspci. I think it is in package pciutils.

sliman · September 22, 2021, 9:45pm

Sorry for late answer, have to work

root@OpenWrt:~# lspci -k
00:00.0 PCI bridge: Lantiq MIPS SoC PCI Express Port (rev 01)
        Kernel driver in use: pcieport
lspci: Unable to load libkmod resources: error -12
01:00.0 Ethernet controller: Qualcomm Atheros AR5008 Wireless Network Adapter (rev 01)

Device was found, but driver not.

Tech-Data says:

WLAN Hardware:
Atheros AR9287
WLAN 2.4GHz:b/g/n
WLAN 5.0GHz:
WLAN driver:
[ath9k](https://openwrt.org/docs/techref/driver.wlan/ath9k)

Loaded with opkg the following:
kmod-ath9k-common 5.4.143+5.10.42-1-1 129.2 KB Atheros 802.11n wireless devices (common code for ath9k and ath9k_htc)

How can I load it into the kernel?

anon4457646 · September 22, 2021, 10:00pm

opkg update
opkg install kmod-ath9k

you don t need ath9k_htc

anyway just in case you are offline, you need kmod-ath9k, kmod-ath,kmod-ath9k-common

sliman · September 22, 2021, 10:15pm

Still online, but have to sleep now =)

Thx for your fast reply.

Will continue tomorrow.

I have to load them then with modprobe?? No, cancel that. Lsmod have the drivers listed, so they already in the kernel, right?

anon4457646 · September 22, 2021, 10:17pm

install that and if needed reboot the device

sliman · September 22, 2021, 10:19pm

ok, image is in ramfs atm.
Will try it tomorrow. Thx2u.

Good night

sliman · September 23, 2021, 5:15pm

Hey all =)

Now my FB 7412 sucessfully works with WLAN available.
Hopefully this topic helps someone else.

Special thanks to @anon4457646 and Mijzelf.

@richb-hanover-priv

Topic can set as solved.
Maybe I could help to update the documentation for this device to add these steps. Give and take.

Have a good evening
