12.10 no wireless connection

[s9032g@comcast.net]

I was finally able to move from 12.04 to 12.10 by burning an iso and doing a complete replacement. Everything seems ok except no wireless.

Ideas? What worked for you?

could tell us what wireless card your machine is using?

and have you tried any of the drivers in the addition driver tool?
if you don't know the card go to a terminal and type

lspci
list the results here.

Thanks

your card is a broadcom BCM4312 same one I'm using.
you will have to connect to the internet via a lan (hardwire connection) then go to system settings > additional drivers
it should offer you to activate broadcom-sta driver. install that reboot and you should be able to connect your wireles.


03:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
the reason this driver is not installed by default is because it's not open source and broadcom has not released the source code. But they do a pretty good job of supporting linux.
Good luck :)

[s9032g@comcast.net]

OK. Am back now
I will try this later today. Is there a terminal command to accomplish installing LP-PHY???

In the past I have had good luck with WICD. I see it is available for 12.10. What would you think about trying that?

I think I would need to get rid of NM first?????

% jockey-text -l

[s9032g@comcast.net]

Sorry to be ignorant.

Just what do the terminal commands above do?

I believe they are command to do an auto install of the drivers needed.

but you can do the same thing but using this command to bring up the Additional driver tool:

sudo jockey-gtk

or install directly by :

sudo apt-get install bcmwl-kernel-source

that should pull the deps needed and make the modules for the kernel-also.
WICD is a good app also. but if you install it you will need to disable network manager which is the default one for ubuntu and work well also.

[s9032g@comcast.net]

I disabled network manager and installed WICD for 12.10. All went well except that no wireless signals were received.

SO I uninstalled WICD and tried the command you suggested to install the proper broadcom driver (matching that on my Dell) Stlll no wireless detection. No connection icon of any kind on top panel.

Only my wired connection works.

how did you install the driver?

and did you reboot after installing it?

[s9032g@comcast.net]

installed with sudo apt-get install bcmwl-kernel-source

seemed to install ok

yes, i have rebooted and shut down several times

[s9032g@comcast.net]

WITH sudo apt-get install bcmwl-kernel-source


yes i rebooted and shut off several times

[kc1di]

installed with sudo apt-get install bcmwl-kernel-source

Well I would use the jokey-gtk command and see what it shows.

Ok lets see what is and is not being loaded.

please copy the following command to a terminal and copy and paste the output here.


lsmod | grep -e wl -e b43 -e ndis

[s9032g@comcast.net]

steven@steven-Inspiron-910:~$ lsmod | grep -e wl -e b43 -e ndis
b43 347284 0
mac80211 461161 1 b43
cfg80211 175375 2 b43,mac80211
bcma 34483 1 b43
ssb 50087 1 b43

How much trouble would I have if I used my 12.04 iso to simply return to a better time? Clean install.

[funicorn]

Don't make things so complicated as they shouldn't be. You ask for command lines, which are given. If you are not sure, refer to the manual using 'man jockey-text' or just 'jockey --help'.

the above shows that wl (STA) is not being loaded.
also you need to remove b43 bcma and blacklist ssb

just go to jockey-gtk and install the proper driver.

Sorry this is taking so long. 12.10 is the tenth distribution of Ubuntu I have loaded, and the first where I lost my wireless connection. Same laptop all the way. Others are having the same problem (google it). I thought that Ubuntu was supposed to be nice for non programmers who weren't skilled at terminal entries.

I just did the above using sudo apt-get update, then sudo apt-get install jockey-gtk. Also used --fix-missing. The jockey-gtk either does not install or installs and disappears.

Also how do I do this "also you need to remove b43 bcma and blacklist ssb"

[funicorn]

let me ask you some, how much time and energy have to be wasted until you are willing to try the command lines

% jockey-text -l
% jockey-text -e <kmod:...>

[s9032g@comcast.net]

I have tried everything suggested by everyone, plus trying WICD.

The problem is, I think, that no one has actually had the problem and solved it (as I asked about in my original thread starter); thus I am getting all sorts of different "solutions" none of which work.

I solved all the 12.10 issues by going back to 12.04.

First time in 10 distros that I had to give up.
