Rasberry Pi 3 wifi not working properly

Postby chaff800 » Fri Dec 15, 2017 2:20 pm

Hi everyone!

So I got this Raspberry Pi3 and decided to install Archlinux. I installed it multiple times due to various problems. The first time I made a mistake and installed the version for Raspberry Pi2. Although it had been working fine for a few hours, I had to erase the micro-sd to use for other stuff. I then installed the version for Pi3 since I'd noticed the first time I had installed the wrong version, but lately I found out that the wifi won't work because there is no 64-bit driver from Broadcom for this. Ok no problem, I just reinstalled the version for Pi2. It worked fine for like a month, and then suddenly something broke. I really can't understand what this is. When I look for the interface with
$this->bbcode_second_pass_code('', '
iw dev

phy#0
Interface wlan0
ifindex 3
wdev 0x1
addr ...
type managed
channel 1 (2412 MHz) ...
')
the interface is there, and also with
$this->bbcode_second_pass_code('', '
ip link:

1: lo <LOOPBACK,UP, LOWE_UP>....
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP>....
3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether ... brd ff:ff:ff:ff:ff:ff
')
I can see it.

If then I try to start wpa_supplicant with
$this->bbcode_second_pass_code('', '
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/config_file.config
')
It returns:
$this->bbcode_second_pass_code('', '
Successfully initialized wpa_supplicant
[ 259.477288] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 259.477496] brcmfmac: power management disabled
')
And if I type
$this->bbcode_second_pass_code('', 'iw dev wlan0 link') it simply tells me it is not connected.

If then I try to shutdown the interface with $this->bbcode_second_pass_code('', 'ip link set wlan0 down') and $this->bbcode_second_pass_code('', 'wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/config_file.config') it gives some more warnings (?):
$this->bbcode_second_pass_code('', '
Successfully initialized wpa_supplicant
[ 586.635197] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 259.646928] brcmfmac: power management disabled
[ 259.646928] brcmfmac: bcrmf_cdf80211_add_iface: iface validation failed: err=-16
Failed to creare interface p2p-dev-wlan0: -16 (Device or resource busy)
nl80211: Faild to create a P2P Device interface p2p-dev-wlan0
P2P: Failed to enable P2P Device interface
')

The configuration file is correct since if I try to connect with a USB wifi adapter it works.
I'd like not to install everything another time, so if you have any idea (which is not buying an adapter) I'd really thank you.

Unfortunately it didn't work
Tried to set it to my current nation (IT), the change takes effect, but then it just won't work
Thanks anyway!
