No Wireless : Broadcom BCM4312 802.11b/g(rev 01)

[angel mike]

I have just done adual boot on my Dell Mini 1010 and cannot get a wireless connectionusing Ubantu but can with Windows XP. The fixed wire internetconnection works fine for both.


I have tried using'Additional Drivers' but get an error message – failed to install.


The systems info (when in Windows) gives :-
Dell Wireless 1397WLAN Mini Card Version 5.10.79.7
Chipset BCM4315/BCM 22062000


Putting lspci code( when in Ubantu) gives:-
Network ControllerBroadcom BCM 4312 802.11 b/g LP-PHY (rev 01)


I have downloadedthe Synaptic Package Manager but not used the code 'bcmwl-kernal-source ' as yet as there are conflicting comments aboutthis in the numerous threads - I have tried to work through these butthere does not appear to be a satisfactory solution that I can see.


Can someone give aclear method of approach on this – I do like the Ubantu concept !

...what version of ubuntu are you using, try a software update...but bheck your software sources first if the needed repos are with check marks.

I have just downloaded ubantu 12.04 from the ubantu web site

What does this report?

lspci -nn -d 14e4:

I wish all the Broadcom questions were this easy!

lspci -nn -d 14e4: gives 03:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
Thanks for replying - I hope your right about it being an easy question !
The ubantu version is 12.04 LTS Desktop and is upto date by the way - downloaded from ubantu.com.

I've been known to be right a couple of times...

Please hook up that working ethernet and do:

sudo apt-get install linux-headers-generic bcmwl-kernel-source

After it completes, detach the ethernet and reboot. Then use your new wireless to give us your report.

I did that but it did not work - here's the output

Reading package lists .... Done
Building dependency tree
Reading state information... Done
E:Unable to locate package bcmwl-kernal-source

The ethernet was working - I reconnected it and was able to use google.

[chili555]

Kernel with an E, not kernal with an A. Please try again.

[angel mike]

Sorry about that - thanks for your patience ! Unfortunately still no wireless connection. Output now reads :

Reading package lists ...Done
Building dependency tree
Reading state information...Done
linux-headers-generic is already the newest version
bcmwl-kernel-source is already the newest version
0 upgrade, 0 newly installed, 0 to remove and 0 not upgraded

Let's probe a bit deeper:

sudo modprobe wl
iwconfig
rfkill list all
dmesg | grep wl

Thanks.
