broadcom pci id 14e4:4320 no connection

freakman420 · 02-28-2010, 02:21 AM

ifconfig wlan0 up
iwconfig wlan0 essid MyRouter key 1234 channel 9 ap 00:CE:NS:OR:ED
dhclient wlan0 <--(dhcpcd not installed)

even on networks that have no encryption & are non mac filtering i cant connect to. i cant use dhcpcd cause its not installed. my card once again is a broadcom 14e4:4320 BCM4306/3 with b43legacy driver installed. ive been looking into modprobe but i think the modules are loaded proper. could be wrong though thats new to me. i think the ndiswrapper isnt really necessary, but if you say otherwise, i'll give it a try. im using backtrack 4 beta. I know this isnt the best way to go since all my configurations are constantly wiped out. I know this much, i can put the card into monitor mode, and scan for networks on both mon0 and wlan0 and see them. here's my config

Code:

root@bt:~# iwconfig wlan0
wlan0  IEEE 802.11bg ESSID:"MyRouter"
       Mode:Managed Frequency:2.452 Ghz Access Point:Not-Associated
       Tx-Power=27 dBm
       Retry min limit:7   RTS thr:off   Fragment thr=2352 B
       Encryption key:AAAA-AAAA-AAAA-AAAA-AAAA-AAAA-AA Security mode:open
       Power Management:off
       Link Quality:0 Signal level:0 Noise level:0
       Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
       Tx excessive retries:0 Invalid misc:0  Missed beacon:0


root@bt:~# ifconfig wlan0
wlan0      Link encap:Ethernet HWaddr 00:CE:NS:OR:ED
           UP BROADCAST  MTU:1500 Metric:1
           RX packets:0 errors:0 dropped:0 overruns:0 frame:0
           TX packets:0 txqueuelen:1000
           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Please don't shun me away cause just cause im using backtrack. its the first distro i ever got into and ive been tinkering with it ever since.

Also, a website (that i wont link to unless u say so) shows that the wlan driver im spose to have is just B43 driver, not the B43legacy. whats the difference? my machine says i have the b43legacy drivers installed.

You have been here?

http://www.linuxwireless.org/en/users/Drivers/b43

Good to know that ndiswrapper blacklists b43*, (/etc/modprobe.d/blacklist) so if you run
modprobe b43
modprobe b43legacy

Nothing will install. Another gotcha is that you need Sonics Silicon Backplane configured in the kernel. There's a little thing called b43_ssb in ssb.ko which actually makes the b43 on usb appear as if it's on pci. The kernel option is
CONFIG_SSB_B43_PCI_BRIDGE=y
I have a broadcom 4312 on my laptop; If I can only see it on lsusb, it's no good. If I can see it on lspci I'm good to go. I use something like

install b43 /sbin/modprobe -i ssb; /sbin/modprobe -i b43; /sbin/modprobe -i btusb

in /etc/modprobe.d. I suggest you modify for b43legacy and try it.

yep, thats the site i was talkin about. as far as the CONFIG_SSB_B43_PCI_BRIDGE option in the kernal, where can i find that? i was in the kernal by typing in the konsole cd ../usr/src/linux then make menuconfig. that the right place?

also i edited the /etc/network/interfaces file to read

Code:

auto lo
iface lo inet loopback

# The primary network interface
auto wlan0
iface wlan0 inet dhcp

it was set up for eth0 as primary.

CONFIG_SSB_B43_PCI_BRIDGE:

Let's go from inside make menuconfig
Device Drivers - Sonics Silicon Backplane
You need CONFIG_SSB_POSSIBLE=m; You also need the b43 stuff selected as modules elsewhere.

/grabs laptop
It now appears to be "support for SSB on pci-bus host" The b43-pci-bridge driver is so small they never bothered setting it up separately. The key thing is that it's autoselected, which it should be by the b43 stuff.
Now save the config and run
grep B43 .config
Among others you should see CONFIG_SSB_B43_PCI_BRIDGE=y

sneaky, eh?

Hello, I'm having the same problem with exactly the same card (pciid “14e4:4320″). How did you solve the problem?

Thanks in advance!
