Notice it is not given a logical name. How do I set it back to being eth1? /etc/iftab seems to be the best option, but I dont know the mac address. Any ideas?
It doesn't seem like /etc/iftab is used anymore, back to square one....
I remarked out # the last line in /etc/udev/rules.d/70-persistent-net.rules, rebooted and wireless started working. Seems upgrade replaced iftab but then setup rules.d with two interface names for the same mac address...
Here the files before I remarked out the redundant entry in rules.d
/etc/iftab
Code:
# This file is no longer used and has been automatically replaced.
# See /etc/udev/rules.d/70-persistent-net.rules for more information.
#
# This file assigns persistent names to network interfaces.
# See iftab(5) for syntax.
##eth0 mac 00:09:5d:15:60:23 arp 1
#wlan0 mac 00:192:BB:50:59 arp 1
/etc/udev/rules.d/70-persistent-net.rules
Code:
# This file maintains persistent names for network interfaces.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-persistent-net-generator.rules
# file; however you are also free to add your own entries.
# Converted from /etc/iftab on upgrade
