Not necessarily helpful to the OP and more for the record for other upgraders:
The wheezy release notes recommend:
apt-get upgrade
apt-get install linux-image-<version>
apt-get install udev
[reboot]
apt-get dist-upgrade
I'd start by checking what versions of the kernel and udev are
currently installed and running because the squeeze kernel isn't
compatible with the wheezy udev.
Can the NIC(s) be brought up and the network enabled manually?
