#! Statler – b43 driver fix.

By , January 15, 2011 12:45 pm

This week I switched to #! (Crunchbang) because my Ubuntu was getting slow.  I love the speed and was very happy with the wifi because it had the b43 driver working by default.  Except, I could not get on my network after the most recent upgrade, but I found a work-around after a day of reading forums.  Surprisingly, it’s not too complicated!  You just need to create a conf file for b43 to use PIO and it will not through a DMA error anymore… my hardware is: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01).  This is the only line you should need.

sudo echo "options b43 pio=0 qos=0" > /etc/modprobe.d/b43.conf

    Hi,

    I tried this but the message came

    permission denied?

    $ sudo echo “options b43 pio=0 qos=0″ > /etc/modprobe.d/b43.conf
    bash: /etc/modprobe.d/b43.conf: Permission denied

    Please why would that be so?

    thanks
