Check /etc/udev/rules.d/70-persistent-net.rules
There you find every network card ever connected to your system with its
MAC address an the assigned interface name, like
---------------------
# PCI device 0x8086:0x4229 (iwl4965)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:ca:fe:00:ca:fe",
ATTRS{type}=="1", NAME="wlan0"
----------------------


Change the entries to fit your needs (e.g. delete your old card entry
and rename the NAME parameter for the current one to wlan0).
Alternatively you can delete all lines and let the system automatically
enumerate all found cards again.
Then stop networking ,restart udev and restart networking afterwards.
