No wireless network HP Pavillion dv4-1548dx with ubuntu 9.10

**aprochaska** · February 14th, 2010

We have an HP Pavillion dv4-1548dx which is now dual boot with Win7 and Ubuntu 9.10. Wireless networking works fine when booted to Windows.
When we boot ubuntu the system doesn't seem to find the wireless device.

Menu>System>Network Connections has no entries in the Wireless tab.
Output of lspci and lshw appear below.

Thanks for any help.

That's a Broadcom 4312 wireless chip in there, and I've been seeing more trouble with those recently for some reason.

Can you also post the results of the following terminal commands here:

Code:

lsmod

ifconfig

iwconfig

uname -a

You might want to search for "broadcom 4312" here- I've seen several threads about trouble with them lately (I suspect a recent update to something is causing it, esp. with Karmic Koala 9.10- I still run Jaunty Jackalope 9.04 with my wireless Broadcom 4321AG and it has been less trouble from what I read here).

edit: It looks like you've also got 64-bit going on, so look for 64-bit fixes specifically (they are often/always? more trouble too).

It looks like your b43 module is loaded (along with the other related "80211" modules). I remember hearing some stuff long ago about blacklisting various modules for that "b43" setup- but a lot of that might be old information now.

Broadcom has released a proprietary driver for that card, and the "STA" driver claims to be written for that 4312 and family specifically (it works great in my Broadcom 4321AG/4328 WiFi).

There are links to how some other people fixed their 4312 wireless on these 2 threads:

http://ubuntuforums.org/showthread.php?t=1410228

Specifically, post #11 here links to the fix:

http://ubuntuforums.org/showpost.php...5&postcount=11

If you want to download the STA driver directly from Broadcom, that is here:

http://www.broadcom.com/support/802.11/linux_sta.php

There is another recent thread about Broadcom 4312 and 4322 wireless here:

SOLVED!

Thank you, northd_tech!
I am posting this from my laptop, by the way ^_^
you have been an enormous help

the second link was the most helpful, for anyone who needs the reference.
