Problem with WIFI, Dell Latitude E5400

[hato_CORP]

Hi;

I have a problem with my WIFI card. Is anybody able to help? I have a Dell Latitude E5400 /Made in Ireland/. Week ago I switched to the newest Ubuntu /I am new user/. The System is great - everything is working perfect besides WIFI card.

System → Administration → Hardware Drivers /recognize TWO drivers/
* Broadcom B43 Wireless Driver /tested by Ubuntu Developers - Free/
* Broadcom STA Wireless Driver /tested by Ubuntu Developers – Proprietary/

First driver is not working.
I am not able to install the second one. There is some faulty information inside a log.
Would anybody help? Which driver will suit my WIFI card?

The first thing needed is the version of the wifi card you have.
Please go to the terminal "Applications>>Accessories>>Terminal (in Ubuntu)" and enter

lspci | grep Wireless

(That is LSPCI in lowercase, W in uppercase)
if you get nothing returned just try

lspci -nn

and look through the long listing and find the network contoller and post the contents back here. It probably will say something "like BCM43xx".

I know it says Dell mini, but these directions seem to be pretty straightforward and work for most people.

[hato_CORP]

Hmm...

I followed the process.
STA driver installed, but WIFI still not working.

Also WIFI light indicator it is not on.

J.

[chili555]

Please do:
sudo rmmod -f dell-laptopPush the wireless switch and see if the light comes on. Any improvement?

If it works, we will have to tweak one file for it to be permanent.

From your other thread on the same page the same advice!

[hato_CORP]

Still nothing.
The problem is that WIFI is still not recognized.

I installed aditional program like WIFI radar. WIFI nor recognized...

So i am still in the same point.

I think we now need to see


lsmod


To see if both drivers are installed and are conflicting with each other.

My apologies for bumbing in with a disruptive post. I am hesitating with this since I really do not have any answers but I have a vague hope that this info might help you to find the problem ifinitesimally faster.

I have Acer laptop with BCM4318 card and when the laptop comes out of hibernation (not suspend) the wireless is disabled.

https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/538658

lshw -C networking returns
*-network DISABLED

So far I have not found any way to enable the wireless from this state except rebooting. So if if you have related problem I am interested in the solution you find in this thread.


Good luck for you guys

Well, you have the "wl" driver which is "STA" , and don't have b43 ( from the earlier posting ) so that seems ok.

Could you now post

sudo lshw -C network
iwconfig

Hopefully we will see the driver associated with the interface.

Sorry about taking so long, but could you do a

sudo modprobe wl

report any errors

and then

sudo iwlist scan

if this doesn't help i will have to do a little googling.

Are you referring to this? sudo mv thefile.conf newnameofthefile.conf.backup. If so, you do realize that "thefile" and "nameofthefile" is not what you type right? What command are you trying? Assuming that you are typing in the right command are you in the right directory? cd /etc/modprobe.d

For some reason it still doesn't seem to associate the STA driver with the interface, here is a really good thread where Ayuthia ( probably the best with Broadcom devices ) solves approximately the same problem giving a lot of detail.

http://www.uluga.ubuntuforums.org/showthread.php?t=1308533

Since you also have a Broadcom ethernet device, you probably can not remove ssb like is shown in post two and would have to modify it as follows:

(sudo modprobe -r b43 wl) to prevent loss of ethernet ( if accidentally done it could easily be added be in, so don't worry!)

I also would go back and remove the second wl shown in modprobe.d, I don't know if that makes any difference other than prettiness.

[newthingstotry]

I have had similar problems with Broadcom 4312 wireless, and installed the STA driver, blacklisted b43, b43legacy, ssb, ndiswrapper and so on.
Forgive my approach, I am a completely newbie to Ubuntu and Linux. I eventually git it to work on a consistent basis, but after a few days my wireless vanished and no matter what I tried I could not get it to come backup. I did a fresh install and tried a lot of the methods described, including that of Ayuthia's great instructions, but somehow nothing seemed to work even though it worked in the last install.
I finally gave up that method and tried ndiswrapper. You may also try it, it worked for me, not straightaway though. From my experience I found that the ssb module was always getting loaded even though I blacklisted it.
I had to write a small script, make it executable and add it to the system startup to prevent from wireless being disabled again and again. Finally I uninstalled network manager and installed wicd from synaptic.
Now it works flawlessly without any issues.
Here is what I did:

1) Installed ndiswrapper and the GUI utility, uninstalled the bcmwl-kernel-source and bcmwl-modaliases from synaptic.
2) Downloaded and extracted the XP driver for bcm4312. I have XP as dualboot so I used winrar to extract the file and placed it in a folder.
3) Used ndiswrapper to get to the.inf file, but that did not make wireless work. I ran lsmod and found that ssb was running at startup and as mentioned blacklisting it did no work, it always started at startup.
4) Wrote a small script with the following commands by doing sudo gedit /etc/init.d/ndiswrapper.sh

modprobe -r ssb
modprobe -r ndiswrapper
modprobe ndiswrapper

5) Saved the file. Made it executable with this : sudo chmod +x /etc/init.d/ndiswrapper
6) To make the script run at startup : sudo update-rc.d ndiswrapper defaults 80

You have been following the STA driver instructions, hope it works. If not you can give
this a try. There are much more detailed instrcutions for ndiswrapper in the forum by
experts, who can help better. Best of luck.

Please keep in mind that you have a Broadcom Ethernet controller

product: NetXtreme BCM5756ME Gigabit Ethernet PCI Express
vendor: Broadcom Corporation

Which probably-perhaps not necessarily--requires the ssb module so if you remove it you may have to put it back in.

Thank You very much.

i accidently did that, would you please tell me how to restore it... and am also still having the wireless not working problem.

Any advice?
