Preparing to install Debian on my new T430, which has an e1000e on eth0
and an Intel Centrino Advanced-N 6205 (supported with iwlwifi and
non-free firmware) as wlan0.
I formatted a USB stick, copied the contents of boot.img.gz,[1] copied
the netinst ISO,[2] and untarred the firmware tarball.[3]. I then booted
from the USB stick, and proceeded through the advanced installer to the
"automatically set up networking" step.
At this point, things went wrong: it decided, despite no cable being
plugged in, that it sensed a link on eth0 and tried to configure
networking. I then tried going into a shell, modprobe -r e1000e, and
then removing e1000e.ko. Now the "detect network hardware" step failed
to detect any network device; the wifi card was apparently not seen.
Then I downloaded the Wheezy 7.3.0 versions of boot.img.gz, the netinst
ISO, and the firmware tarball, and put them on the USB stick. This
detected the wifi card correctly and asked which I wanted to use to set
up networking. At this point I aborted the install, because I had yet to
install my new SSD.
