At me DWL-g520 +

Jeff Long

Thanks a ton, I’ve used this twice now. Once on an Emachines M5312 Laptop / Broadcom Wireless 54g, and just now on my desktop with a Linksys WMP11.

ColtonCat

Very nice indeed…!!! Thanks for the Howto

Adam

I am always grateful for those who work through problems, find solutions, and then share them with the world. One thing I’ll post for those who may have a Motorola 802.11G PCMCIA card is that do NOT use the standard Broadcom drivers floating around that work in most cases, only the drivers from Motorola (bcmwl5.inf and bcmwl5.sys) that are packed in an *.exe file work.

Fuad

can it work on modem driver?

Lyubich, M

Great HOWTO! Thanks.

I have an additional point. I used wine from FreeBSD port collection to run the selfextracting archive (*.exe) and to extract the valuable (*.inf and *.sys) files.

Regards, ML

Doesn’t work for me, i have a broadcom 802.11b/g (same driver file names as your example even).

ifconfig ndis0 reports that the interface doesn’t exist…

João Henrique

SOLVED: just follow the direction found in http://www.freebsd.org/cgi/man.cgi?query=ndisgen&sektion=8&manpath=FreeBSD+6.0-RELEASE

Good luck!

everything seems to go ok.. but when i run kloads… i get this

kifkroker# kldload ndis
kldload: can’t load ndis: File exists
kifkroker# kldload if_ndis
kldload: can’t load if_ndis: File exists

thanks for your help in advance.

Sander’s Weblog » FreeBSD and Wireless PCI Card

[…] Initially, I came away with a LinkSys WMP11 card that would cost me, after two rebates, the grand sum of five dollars. I had googled for this product and found out it is based on the well-supported Prism chipset, so I took one home. However, the card I had bought turned out to be a new revision, with a completely different chipset that the FreeBSD developers had never heard of! Thanks Linksys for springing that on the unsuspecting public. Of course there are Windows drivers, so the unsuspecting public still has something to play with. As, it turned out, did I. I turned to the NDIS wrapper support and found out that this only came with FreeBSD 5: time to upgrade the box from 4-STABLE. After a fresh new install (the only thing building world did for me was make every program I started dump core… boy was I glad that I had backed up my home directory before I started on this track), I got the NDIS driver to work (great hints by Dannyman), but unfortunately it did not support WEP. Why do we care about WEP? Isn’t it completely uncool to rely on WEP these days? Actually, it is in a way. In the same way that the lock on a bathroom stall door prompts most people to try the other stall, I assume the 1337 H@x0R is going to hook up to the unencrypted network first and I can see up to six open networks from my second bedroom.

João Henrique: i’m facing the same problem here. Everything goes well until the ifconfig ndis0 up, where he says, that the interface ndis0 does not exist. How did you fixed it?? On that link that you’ve posted is only the man page but no instructions…

Can somebody else help me with that?

kevin

so anyone had any luck doing this on FreeBSD AMD64?

im D/L’in AMD64 right now let cha know how it goes

Mario Castelao

To everybody having problems with:
#kldload ndis
kldload: can’t load ndis: File exists
#kldload if_ndis
kldload: can’t load if_ndis: File exists
or:
#ifconfig ndis0
ndis0 does not exist

The solution was posted by João Henrique but if you want a more detailed explanation here you go:
start by using ndisgen, its synopsis is:

ndisgen [/path/to/INF /path/to/SYS]

therefore:
#cd /sys/modules/if_ndis/
#ndisgen bcmwl5.inf bcmwl5.sys
and then follow the “wizard”, (basically pressing “enter,return” a few times…) and generate the following bcmwl5_sys.ko , after this you can either load the module by typing the command:
#kldload /sys/modules/if_ndis/bcmwl5_sys.ko
or create a link to the module in the /boot/kernel and then load it:
#ln /boot/kernel/bcmwl5.ko /sys/modules/if_ndis/bcmwl5_sys.ko
#kldload bcmwl5_sys.ko
or copy it into /boot/kernel and then load it:
#cp /sys/modules/if_ndis/bcmwl5_sys.ko /boot/kernel/bcmwl5.ko
#kldload bcmwl5_sys.ko
after all of this you can simply add in your /boot/loader.conf the following line to load the module on boot:
bcmwl5_sys_load=”YES”

Hope it helped,

br0(rus)

I found solution about trap 12. First you need bcmwl5.inf with version is 3.xxx not 4. I have 3.140, from HP site here: http://h20000.www2.hp.com/bizsupport/site/search/r4_0/jsp/search.jsp?lang=en&cc=us&tx=Broadcom+Wireless+LAN+Driver&sc=1&nh=10&rf=0&lkc=1&lk=1&sts=1
Also you will need to patch file nsubr_ntoskrnl.c – of ndis module, you can find here /usr/src/sys/compat/ndis/

Here is patch:

Hey br0(rus)!

Why not post the patched ko module? I’m having difficulty patching using FreeBSD 6.2 and would love to test your module for the Realtek 8185 via NDIS. Btw, great how to article dannyman. Thanks!

[…] step by step tutorial on how to use ndisgen can be found here and here. I haven’t tried it yet, but it looks similar to […]

Pablo Sánchez

Greetings.

I followed the how-to quite well, got no problems at all, except for you thing:

The module loads, but no new network interface appears! There are no errors, only the driver is loaded (kldstat shows it) but nothing happens!

FreeBSD 7.2 amd64

The interface is a broadcom.
