 |

I would like to configure wifi on my rpi4 but unfortunately I didn't find any howto's. Can anybody tell me, how I can reach this?

ROGA,
The only special steps for the wifi on the Pi4 are the firmware files.
| Code: | brcmfmac43455-sdio.raspberrypi,4-model-b.txt
brcmfmac43455-sdio.bin |
They go into /lib/firmware/brcm/ and are not provided by linux-firmware
After that, the configuration for wifi is the same as you would use for wifi on whatever network control tool you use.

Hi ROGA,
files are available from:
https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm
Please note that modern versions of linux-firmware do provide the brcmfmac43455-sdio.bin file, but that that version is out of date wrt Raspbian (very bad performance in certain cases on the RPi4B), and you should use the copy from firmware-nonfree instead. Please see this post for further details.
PS I have an ebuild for these additional firmware files (used in my gentoo-on-rpi-64bit project); please see here.

Hi Sakaki,
I did what you posted and had updated successfully the firmware file brcmfmac43455-sdio.bin. Unfortunality I didn't find the file brcmfmac43455-sdio.raspberrypi,4-model-b.txt that NeddySeagoon mentioned in the given git-hub repository.
Do I not need a newer file from that git-hub repository? I guess that I have this file alredy in the /lib/firmware/brcm directory that was comming with the linux-firmware package, should I use this?

ROGA,
brcmfmac43455-sdio.raspberrypi,4-model-b.txt is a file that provides data to the Wifi driver that would normally be in the UEFI firmware.
Put the file name into google. It will find it.

NeddySeagoon, ROGA,
Interestingly, I've just installed a fresh copy of Raspbian Buster (the 2020-02-13 "with desktop" image, SHA-256: a82ed4139dfad31c3167e60e943bcbe28c404d1858f4713efe5530c08a419f50) and it does not have the /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt file present. It does have /lib/firmware/brcmfmac43455-sdio.txt, matching the version from the firmware-nonfree repo (md5sum 7b983812a8aee7bf701460436c686226) - however this differs materially from brcmfmac43455-sdio.raspberrypi,4-model-b.txt (md5sum 2c1dc81266ac61dfc0a809cc48fffbfb):

Is the (apparently more specific) brcmfmac43455-sdio.raspberrypi,4-model-b.txt definitely the correct one to use here, given that it is not seemingly shipped with Raspbian?

Hi Sakaki and NeddySeagoon
sorry, but I'm not able to configure my wifi on my raspi 4. I installed
| Code: | | emerge -av wpa_supplicant |
I configured /etc/wpa_supplicant/wpa_supplicant.conf
| Code: | ctrl_interface=DIR/var/run/wpa_supplicant GROUP=wheel
update_config=1
network={
ssid="MYSSID"
#psk="MYPASSWORD"
psk=f7a8ffc6b5bc8fd0a1fb594368379601c467b178c56b6b45edb6f0390e03aee8
}
country=CH |
and had configured /etc/systemd/network/wlan.network
| Code: | [Match]
Name=wlan0
[Network]
DHCP=yes
|
then started systemctl start wpa_supplicant.service but unfortunately nothing happens.
ifconfig show me
| Code: | wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether dc:a6:32:20:06:a2 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX error 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 |
does anybody know, what I'm doing wrong?
PS: this is my dmesg

Hi,
Your dmesg output isn't available any more. Do you use dhcp?
