Linuxmint 14 Cinnamon up to date
Dell Inspiron 6400 laptop
Dell Wireless 1490/Broadcom BCM4311 wifi card
I tried out the Trisquel LiveCD via a USB flash drive and was surprised to see that it successfully brought up my wifi. This is FSF-approved free software, so I thought my Linuxmint should be able to run my wifi card as well.
I used the Linuxmint package manager to install
and did a
sudo apt-get install firmware-b43-installer
in a terminal window.
I didn't see my wifi card in Network Connections, so I rebooted.
My ethernet was gone! ifconfig only shows loopback; nothing else. There's no MAC address in my wired Network Connections.
I thought installing the broadcom packages caused my ethernet problem, so I uninstalled them and rebooted again. I still have no ethernet in Linuxmint.
I'm using Window$ to post this from the same machine. Nothing wrong with my ethernet in Window$ and Window$ has always worked with my wifi card.
