Excellent Release...and an FYI on Broadcom Wireless.

6.0-rc1 is excellent!

An FYI for those who may be using the Broadcom BCM43xx wireless adapter (popular with integrated Dell Inspiron Notebooks):

The kernel, evidently, supports the wireless adapter; requiring only fw cuts (bcm43xx_microcode5.fw for my daughter's Inspiron B130).

Loading the bcm43xx driver is redundant and will give one problems in attempting acquire an AP.

After doing...
apt-get install bcm43xx-fwcutter (bcm43xx-fwcutter_20060108-6build1_i386.deb)
apt-get install wpasupplicant (wpasupplicant_0.4.8-3ubuntu1.1_i386.deb)
apt-get install airsnort (airsnort_0.2.7e-1.1_i386.deb)

I muddled my way into cobbling-up the following work-around...

Created the following scriptlet: (ignore all the line break tags...weird!)

# begin /usr/bin/wlan-start.sh<br />
#! /bin/sh<br />
rmmod bcm43xx<br />
rmmod ndiswrapper<br />
modprobe ndiswrapper<br />
# end /usr/bin/wlan-start.sh

Made it owned by root and executable (of course).

Added the following at the end of

/etc/network/interfaces

# begin added line<br />
pre-up /usr/bin/wlan-start.sh<br />
# end added line

At this point, the notebook now boots with wireless enabled, AP acquired, and connection established.

It may be nothing more than a hack, but it produces the correct result.

Broadcom 43xx chip

For those who have an Adapter with the 43xx Broadcom chipset (Such as my Linksys WMP54GS) read on! If your Mepis Control Center Networking - shows your wireless on eth0 or eth1 and does not show it on wlan0 - here was my fix.

Go to: /etc/modprobe.d/blacklist

Add the following to the blacklist:

# Broadcom Native Driver
blacklist bcm43xx

Reboot and fill in the settings for your wireless in the Mepis Control Center Networking and mark wlan0 to start on boot.

Reboot again or restart wlan0 and you should be hooked up!

No need to mess with ndiswrapper!

In my situation, I did, as

In my situation, I did, as root:

echo 'blacklist bcm43xx' | tee -a /etc/modprobe.d/blacklist

...which made no difference in the issue I was having with the wireless, so I just jammed what I knew would work into the script and went with it.

Now that you've made me think about it a bit more, I went back to my daughter's notebook and checked the /etc/modprobe.d/blacklist file.

The final line was:

blacklist i2c_i801blacklist bcm43xx

Splitting the entry into

blacklist i2c_i801

blacklist bcm43xx

took care of the issue, and /etc/network/interfaces is back to its original state.

What I did, maprx, was just reacting without digging into why things didn't go the way I expected them to; which is why I did the unnecessary scripting.

If you do what adamhenry1 says,

Go to: /etc/modprobe.d/blacklist

Add the following to the blacklist:

blacklist bcm43xx


you shouldn't have any problems with the wireless on the B130. I presume that you would give the e1705 similar treatment.

is there any way to

is there any way to blacklist the bcm driver when booting on the live cd

Ndiswrapper on live CD ???

In theory you could do (as root)
rmmod bcm43xx
rmmod ndiswrapper
modprobe ndiswrapper

and then proceed to configure your card with ndiswrapper

but many times ndiswrapper needs a reboot to get your connection working.

I haven't tried this on the live CD.

Does this answer your question?
