Cannot connect via wifi with Broadcom 4313 / brcmsmac

vpoinot · 2012-05-28 11:38:35

I am trying to get wpa_supplicant working with my Broadcom 4313 wifi card.
According to https://wiki.archlinux.org/index.php/Broadcom_wireless, I should use the driver bcrmsac (my card's PCI id is [14e4:4727]). And indeed, I can see that udev selects this driver at boot time.

However wpa_supplicant cannot connect to my network: I frst thought it was a WPA / wrong key issue, so I disabled any encryption... and it still does not work.

In my wpa_supplicant.conf, I have:

update_config=1
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
ap_scan=1
fast_reauth=1

network={
        ssid="MySSID"
	key_mgmt=NONE
}

I try to run wpa_supplicant in debug mode with:

wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf -d

which produces:

...

As far I understand, the line that says "WEXT: cfg80211-based driver detected" is good; I also see that wpa_supplicant goes from state DISCONNECTED, to SCANNING, then finds my ssid (MyNetwork), goes to ASSOCIATING, then ASSOCIATED and COMPLETED. All this looks good to me.

What is weird is the next lines:

Wireless event: cmd=0x8b15 len=24
Wireless event: new AP: 00:00:00:00:00:00
Disassociation notification
Setting scan request: 0 sec 100000 usec
Added BSSID <my MAC address> into blacklist
CTRL-EVENT-DISCONNECTED bssid=<my MAC address> reason=0
State: COMPLETED -> DISCONNECTED

What is this new AP: 00:00:00:00:00:00 ? Why does wpa_supplicant blacklist my MAC address ? What is going on here ?

Thanks a lot for any help.

Any idea, hint, clue anyone? I am completely stuck, here...

Scroll down and you will see that you can use the broadcom-wl driver. I have the same card and the broadcom-wl worked for me.
