howto: Wireless on DELL Inspiron 1525 (BCM4312)

wombat · 2008-09-20 11:49:12

Hello. I am not sure wheter there's a thread explaining how to get BCM4312 working. Because I searched and I just didn't found anything that works for me.

However, I'll write what worked for me.

HOW TO GET BCM4312 working on DELL Inspiron 1525 (might work on other brands/models, I don't know. I am just writing quickly what worked for me).
1. Determine wheter you actually have this card (BCM4312).
type in console

lspci | grep BCM43

Mind the letter-case. If you have this card you'll see it. You might have BCM43xx where xx differs from 12. In this case you could try the b43 driver. Or find more info elsewhere.
2. Go here and follow the instructions in the README file.
(here's what I actually did after downloading the driver:

tar -xzf hybrid-portsrc-x86_64.tar.gz
make -C /lib/modules/2.6.26-ARCH/build M=`pwd`
rmmod b43
modprobe ieee80211_crypt_tkip
insmod wl.ko

)
3. Type in a console (you should have wireless_tools installed, i.e. `pacman -Sy wireless_tools`):

iwconfig

You should have an entry, similar to this:

eth1      IEEE 802.11bg  ESSID:""  Nickname:""
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
          Bit Rate:54 Mb/s   Tx-Power:32 dBm
          Retry min limit:7   RTS thr:off   Fragment thr:off
          Power Managementmode:All packets received
          Link Quality=5/5  Signal level=0 dBm  Noise level=0 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

That's it. I hope that this will help someone.
PS: Next you can check out wlassistant- it's a GUI tool for connecting to wi-fi. (there are others of course)

Could you please submit that to the wiki?

Also when I bought my Inspiron 1525n the wireless was recognized as an USB BCM4310, however after one of the updates it was recognized as BCM4312, and only managed to get it working with ndiswrapper...

Confirmed working! So long ugly ndiswrapper days
Here's the package in aur.

For building on x86_64 (I couldn't figure out how to use different source on if arch=x86_64 (could someone help me with this?)

I took the liberty off adding a wikipage.

Okay,I'm glad it works. I was kind of busy lately, so that's why I wasn't able to look at this topic.
PS: btw,DHeart, радвам се, че съм помогнал на друг сънародник (и съгражданин, де)

Reloaded PKGBUILD in AUR for both archs. Please check x86_64.

I can't build the module:

I don't understand the error message. Can anyone give me a hand?

FIrstly, you should use the broadcom-wl package in the AUR.

Secondly, this is a two-year-old thread.

Closed.
