/sbin/ip link addr show That will tell you the names of your interfaces, as they currently exist. You cannot reliably use 70-persistent-net-rules to assign interfaces names which the kernel may chose. This means things like 'eth0' and 'wlan0' are unreliable in principle. Once you know what the interface name will be, rename /etc/init.d/net.eth0 to /etc/init.d/net.$YOUR_INTERFACE_NAME_HERE , remove /etc/runlevels/net.eth0 and create a symlink in /etc/runlevels pointing at your new /etc/init.d/net.$WHATEVER file. Then /etc/init.d/net.$WHATEVER restart ... and things should come up, at least partially. To find anything else that might be broken: find /etc|grep eth0 find /etc -print0|xargs -0 grep eth0|egrep -v ':#' and rename 'eth0' there to your new interface name. I just went through this entire process on one of my machines...but I wiped all the files out of /etc/udev/rules.d/ and went with udev's new defaults, rather than set up my on persistent net rules for this machine. (That's a task for another day.) Frankly, the process is a PITA...and I'm going to go back to a persistent-net.rules file in the future; having to go through that entire process because of a NIC swap or an upstream behavior tweak is not something I care to have to do.
