The usual suspect for issues with the names of network devices is
/etc/udev/rules.d/z25_persistent-net.rules.
As far as the general problem with the device is concerned: It seems
that eth1 in the new install is accepted as a wireless network device,
so it should work. Did you adjust the data in /etc/network/interfaces to
match the new name of the device? Ifup needs this information to set the
ESSID, encryption key, etc.
