 Posted: Sun Jul 20, 2014 11:10 pm Post subject: [Solved] Broadcom BCM4312 configuring via wpa_supplicant |
 |
|
Not sure how to configure wpa_supplicant.. 
read this: https://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=4&chap=4#doc_chap2
got stuck after realizing I dont know what to put as the driver. I have a Broadcom BCM4312 but im not sure what to write in the wpa_supplicant_eth0=" "
Also, I see a lot of other stuff on the web where theirs are wpa_supplicant_wlan0 instead of eth0. why is that?
and how do i make a ASCII passphrase? http://en.wikipedia.org/wiki/ASCII#ASCII_control_characters
do i type it in binary or something?
Thank you in advanced

hi there,
Don't worry about being confused, we all started off in the same boat as you are now 
The manual is a bit unhelpful there as there a very few wifi drivers which are not in-kernel these days. Basically all the in kernel drivers use the nl80211 wireless stack, and so you want -Dnl80211. If that doesn't work, then the older "wireless extensions" stack should do the trick. You most likely simply want a setup with:
| Code: |
# /etc/conf.d/wpa_supplicant
wpa_supplicant_args="-Dnl80211"
#if that fails try
#wpa_supplicant_args="-Dwext"
|
and
| Code: |
# /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel # this line specifies a "control socket", it is not necessary, but it allows any member of wheel to use wpa_cli to control wpa_supplicant behaviour.
network={
ssid="my_ssid"
psk="myp4$$phr4$3"
}

Telemin ... /etc/conf.d/wpa_supplicant is only used if the /etc/init.d/wpa_supplicant service is used, which generally isn't the case as most often wpa_supplicant is started via 'net.wlan0'. To provide the same parameter one would do the following:
/etc/conf.d/net
| Code: | | wpa_supplicant_wlan0="-Dnl80211" |
@ShanaXXII ... "eth0" (or whatever your interface is called) is "wired interface", whereas "wlan0" is "wireless interface".

Not sure what you're asking exactly, if the passphrase from the AP is 'psk' then use 'psk=A1B2C3D4E5etc' in wpa_supplicant.conf, if you need to generate a psk *from* an ASCII passphrase then you can do the following ...
| Code: | | # wpa_passphrase <ESSID> passphrase |

so this is what my /etc/conf.d/net looks like so far
| Code: | # /etc/conf.d/net
modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dn180211"
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
SSID="TP-LINK_62ECB4"
psk="The password to my wifi"
priority=5
} |
and
| Code: | # /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
ssid="TP-LINK_62ECB4"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
psk="my wifi password"
priority=2
} |
is there anything wrong? |

ShanaXXII ... yes :) ... you have stuff (from wpa_supplicant.conf) in /etc/conf.d/net ... something like the following should be sufficent ...
/etc/conf.d/net
| Code: | modules_wlan0="!plug wpa_supplicant dhcpcd"
wpa_supplicant_wlan0="-Dnl80211 -qq"
config_wlan0="dhcp"
enable_ipv6_wlan0="false" |
Also you had "n180211" (digit, one) and not "nl80211" (lower case "el").
For the wpa_supplicant.conf most of the parameters can be left out as wpa_supplicant will generally be able to auto detect them and select the best available.
/etc/wpa_supplicant/wpa_supplicant.conf
| Code: | ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
network={
ssid="TP-LINK_62ECB4"
proto=WPA2 # I don't imagine the TP-Link won't support wpa2
psk="my wifi password"
priority=2
} |

okay. So I changed my /etc/conf.d/net and etc/wpa_supplicant/wpa_supplicant.conf
How do i know if i have wireless connection or if wireless connection has started? and how do i start it? |

ShanaXXII ... you should now be able to start the service ... if you created the symlink to net.lo
| Code: | # ln -s /etc/init.d/net.lo /etc/init.d/net.wlan0
# /etc/init.d/net.wlan0 start |
If you want the the wireless connection to start when booting you can add it to the 'default' runlevel
| Code: | | rc-update add net.wlan0 default |
Assuming there are no errors you should then be able to either test, or use, the network
| Code: | # wpa_cli status
# iwconfig wlan0
# ping -c 1 204.187.15.12
# ping -c 1 forums.gentoo.org |

ShanaXXII ...
there is some odd output in the above ('net.wlan", "wla0") I'll assume you typed this by hand and that these are typos. So, lets see what the name of your wireless interface actualy is, this way we know if the device is recognised and the drivers are available ... can you post the output of 'ifconfig -a' (as it looks like your typing this by hand just provide the names of the interfaces on the left column).
here I have ...
| Code: | # ifconfig -a | awk '/^[[:alpha:]]/{print $1}'
lo
wlan0 |
That is the 'loopback' (lo) interface, and the wireless interface (wlan0) ... the ethernet (wired network) driver currently isn't loaded. I suspect that you're using udev and the wireless device has been renamed 'wlp2s0' (or similar).

ShanaXXII ... ok, so there is no wireless interface, this means that either the driver isn't loaded or the kernel/driver is missing something (possibly firmware).
I've not had any experience with this particular card, so I'm not sure what exactly needs to be done here (or even if the in kernel driver is the best option ... as there is also net-wireless/broadcom-sta). I'll assume that the in kernel driver will work so assuming you haven't installed net-wireless/b43-fwcutter and got the required firmware please try the following (you will need to have network for this so if you have no ethernet then you will need to use a boot disk that supports your wireless card):
| Code: | # cd /usr/src
# wget -O broadcom-wl-4.178.10.4.tar.bz2 http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2
# tar -xjvf broadcom-wl-4.178.10.4.tar.bz2
# cd broadcom-wl-4.178.10.4/linux
# emerge net-wireless/b43-fwcutter
# b43-fwcutter -w /lib/firmware wl_apsta.o
# modprobe -r b43
# modprobe b43
# ifconfig -a |
Hopefully this will be enough to get the card working, if not then post the relevant sections from 'dmesg'.

I did everything in the above. when I did
# modprobe -r b43 it gave me an error saying:

Ummm .... I'm confused, because the above shows the connection established. This could just be a typo somewhere in your configuration but I don't know why it fails but you still get connected ... is that the exact error, you don't also have wpa_supplicant in the runlevel?

U are right, I do have wireless connection . Thank you.
but i still have the errors when booting up. It hangs there for about 10 secs or so. and I said something about deleting var/run/wpa_suppllcant/wlan0 if its not needed

ShanaXXII ... wpa_supplicant is in the default runlevel and should be removed ... net.wlan0 will start wpa_supplicant so by having both wpa_supplicant and net.wlan0 start there would be a conflict, that was probably the cause of the above error.
| Code: | | # rc-update del wpa_supplicant default |
Everything should now be error free ... if not let me know.

One last question: if i wanted to connect to another wireless connection. Do I have to erase the setup i had with this wireless connection -> /etc/wpa_supplicant/wpa_supplicant.conf.
or can i just start another bracket and write it there?
e.g.
| Code: | network={
ssid="TP-LINK_62ECB4"
proto=.....
...........
......
}
network={
ssid="rogers...."
......
} |

ShanaXXII ... yes, you can have as many 'network' blocks as needed, you can also provide names for these networks with 'id_str='. If one or other network isn't available wpa_supplicant well select one that is (based on 'priority=').
There are many ways to go about switching networks, I use wpa_cli but you might want to add the 'qt4' useflag and use wpa_gui (your user will need to be in the wheel group).
