HOWTO: Dell Inspiron E1505 Wireless (Broadcom 1390 WLAN)

This HOWTO describes how to get Wifi working on your Dell Inspiron E1505/6400 laptop using Ndiswrapper. This applies if you have the Broadcom "Dell Wireless 1390 WLAN MiniCard", which as far as I know, is the cheaper, low-end version that Dell currently offers in this laptop. This HOWTO has been tested and works with both 32 bit and 64 bit ubuntu, and uses the exact same method for both. It is VERY IMPORTANT that you read every part of this how-to and follow the steps EXACTLY as they're written. Many users have trouble because they only read the code sections and ignore my directions to change to the proper directories. Again, PLEASE BE SURE YOU ARE IN THE PROPER DIRECTORY WHEN EXECUTING THESE COMMANDS. This will save you a lot of trouble and will make the installation go a lot smoother.

This HOWTO supports:

• Gutsy Gibbon 7.10
• Feisty Fawn 7.04
• Edgy Eft 6.10
• Dapper Drake 6.06

STEP 1: CLEAN YOUR SYSTEM

IMPORTANT NOTE ABOUT CLEANING YOUR SYSTEM:

One of the most common reasons why many people can't get their wireless working is because their system is in a state of chaos. If you have made ANY previous attempts to get your wireless working -- either using fwcutter, ndiswrapper, or the bcm43xx drivers -- this how-to will most likely not work UNTIL you reverse your previous changes. In many cases, it is much easier to simply reinstall ubuntu and come straight to this how-to. Alternatively, you can manually clean your system of the previous attempts, as outlined in various posts throughout this thread. But BE WARNED: If you have done ANY previous work on your wireless, there is almost no chance that this how-to will work unless you clean your system.

If you have a fresh install of Ubuntu, you need to remove any and all versions of Ndiswrapper that come installed by default on your system:

Code:

---

sudo rmmod ndiswrapper
sudo ndiswrapper -e bcmwl5
sudo apt-get remove ndiswrapper-utils

---

Don't worry if you get errors about not being able to find or remove these -- we're just making sure they're not present before we get started.



STEP 2: GET NEEDED PACKAGES

We'll need to install compiling tools (don't panic when you read that, just bear with me), the latest kernel headers, and then the source code for the latest ndiswrapper (seriously, don't panic. This will be very simple), and the wireless drivers from Dell.com.

Code:

---

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install linux-headers-`uname -r`
wget http://ftp.us.dell.com/network/R151517.EXE

---

NOTE: The characters around `uname -r` are BACK TICS, NOT apostrophes. A back tic is usually located at the top left of your keyboard, to the left of the 1 key. The command WILL NOT WORK if you use apostrophes. Just copy/paste the commands from this how-to in to your terminal to avoid making typos.

At this point, you need to go to the ndiswrapper sourceforge site and get the latest version of the Ndiswrapper program.

Code:

---

wget http://superb-east.dl.sourceforge.net/sourceforge/ndiswrapper/ndiswrapper-1.51.tar.gz

---

If that wget doesn't work, just go here: http://sourceforge.net/project/showf...group_id=93482

Uncompress the ndiswrapper source (in my example, the file name is ndiswrapper-1.51.tar.gz):

Code:

---

tar -xzvf ndiswrapper-1.51.tar.gz

---

Finally, we need to blacklist the broken and useless bcm43xx firmware drivers that try to load in a default ubuntu install:

Code:

---

sudo echo blacklist bcm43xx >> /etc/modprobe.d/blacklist

---

NOTE: If the above command gives you a permission denied error, try this code instead:

Code:

---

sudo -s
echo blacklist bcm43xx >> /etc/modprobe.d/blacklist
exit

---

YOU MUST REBOOT NOW!



STEP 3: COMPILE PROGRAM

Now we'll complile the Ndiswrapper program. In a terminal, go to the directory where you extracted ndiswrapper and execute the following:

Code:

---

cd YOUR-NDISWRAPPER-DIRECTORY
sudo make uninstall

---

IMPORTANT: Do the above command multiple times. You can stop when you get the message that says something about no files or directories found. This usually means running the command 2 or 3 times, but not more than about a dozen.

Code:

---

sudo make distclean
sudo make
sudo make install

---

STEP 4: INSTALL DRIVERS

If that worked, then you now have Ndiswrapper installed. Now we need to install the drivers. In a terminal, go to the directory where you have the R151517.EXE file:

Code:

---

unzip -a R151517.EXE

---

Now change directories to the DRIVER directory that was just extracted.

Code:

---

cd YOUR-DRIVER-DIRECTORY
sudo ndiswrapper -i bcmwl5.inf
sudo ndiswrapper -l

---

you should see a message that says driver present, hardware detected

Code:

---

sudo ndiswrapper -m
sudo modprobe ndiswrapper
sudo echo ndiswrapper >> /etc/modules

---

NOTE: If the above echo command gives you a permission denied error, try this code instead:

Code:

---

sudo -s
echo ndiswrapper >> /etc/modules
exit

---

Some users have reported the need to reboot here.



STEP 5: TEST WIRELESS

Your wifi light on your laptop should be illuminated, and you're all set! Try running this to see if your wireless card is functioning properly:

Code:

---

sudo iwlist scanning

---

Even if it doesn't detect any wireless networks in range, it will still tell you if linux is recognizing your wireless card properly. If you'd like a better way to scan for wireless networks, I'd suggest installing/using network-manager or wifi-radar.


TO ALL WHO REQUEST HELP:

1) Please indicate:

1. your laptop model
2. ubuntu version
3. your lspci output
4. the relevant rows from /var/log/syslog
5. the relevant rows from dmesg
6. any unexpected output when following the steps in the how-to

2) If your wireless card is being recognized by the system, but you simply cannot connect to your desired wireless network, please understand that your issue is beyond the scope of this how-to, due largely to the fact that such issues are very complicated and often have absolutely nothing to do with the way you got ubuntu to recognize your wireless card. That said, I will do what I can to help. My first suggestion will always be to turn off all encryption first to see if you can at least connect to an open network.

NOTES:

- Dell driver version updated to R151517.EXE on 30 March 2007
- Ndiswrapper version updated to 1.51 on 7 January 2008
- If you are using a Dell laptop that's NOT model E1505, you need to go to Dell.com and search for the drivers that correspond to your specific model. Use those instead.

Great ! thats a nice, easy how-to - and works perfectly. I needed to manually put an ESSID from the last command into the the config of the wireless card (system->administration->networking) - it wouldnt auto-detect networks there. If all need to do it, you might want to add it in the how-to !

Ty for this, working fine now

Thank You. U save me. I was using windows because i couldn't set up my wireless connection. Now it's working fine and it was very easy to configure. Thanks :-D

God bless you!

I get the same result as before, no wireless. The light doesn't come up and the scan is empty. I can't connect to any networks. This is really annoying because wireless was working PERFECTLY under Dapper. I'm really _really_ disappointed with Edgy. Nothing seems to work (wireless, XGL/Beryl, suspend and hibernate). I'm going to mess around with it for a while but I might just go back to Dapper.

i have a problem, and i'm new to linux in general, so i apologize ahead of time for not completely understanding the answers if that happens.

when i go to blacklist the bcm drivers, it says permission is denied. what do i do to get around that? i'm using sudo, and i've already typed in the only password i know of. what's going on?

so nevermind on that, i logged in as root and fixed the problem. the next thing is that i'm actually having trouble with an earlier step.

sudo apt-get install linux-headers-`uname -r`

this command gets me the following reply:

Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package linux-headers-uname -r

again, i'm completely new to linux and don't know what i'm doing wrong. anyone?

Open a new terminal and do "sudo -s" and then try the same code without the sudo.

see where it says "uname"? that;s where you enter the linux headers version number. first type "sudo apt-get install linux-headers" and it will give you a selection and then choose the version replaced with "uname"






However, I am having problems installing the driver. It is giving me the error with something like "code at line 167". Any ideas?

i'm getting the same line 167 message now.

and it's showing that i've got like three drivers installed somehow. how can i remove specific drivers for the device?



and thank you very much for the previous answer. that was extremely helpful.
