This showed no useful information. The only output is from my EEEPC below, the 
Aspire showed no output at all.

root@protheus7:/home/ullhan63# grep -E '(enp|eth)' /var/log/dmesg

Yes, this is Aspire with eth0:
# This file was automatically generated by the /lib/udev/write_net_rules 
# program run by the persistent-net-generator.rules rules file. 
# 
# You can modify it, as long as you keep each rule on a single line. 

# PCI device 0x168c:0x001c (ath5k_pci) 
SUBSYSTEM=="net", ACTION=="add", 
DRIVERS=="?*",ATTR{address}=="00:1d:XX:XX:XX:XX", ATTR{type}=="1", 
KERNEL=="wlan*", NAME="wlan0" 

# PCI device 0x10de:0x054c (forcedeth) 
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="1c:75:YY:YY:YY:YY", ATTR{type}=="1
", KERNEL=="eth*", NAME="eth0" 

# Firewire device /sys/devices/pci0000:00/0000:00:08.0/0000:01:04.0/fw-

ATTR{address}=="00:02:3f:ZZ:ZZ:ZZ:ZZ", ATTR{dev

I changed the MAC cause of security purposes in this mail.


Same for EEEPC:

# This file was automatically generated by the /lib/udev/write_net_rules 
# program, run by the persistent-net-generator.rules rules file. 
# 
# You can modify it, as long as you keep each rule on a single 
# line, and change only the value of the NAME= key. 

# PCI device 0x1969:0x1062 (atl1c) 
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="90:e6:XX:XX:XX:XX", ATTR{dev_id}==
"0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 

# PCI device 0x168c:0x002b (ath9k) 
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", 
ATTR{address}=="00:25:YY:YY:YY:YY", ATTR{dev_id}==
"0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

Changed MAC, too, but you can of course still see the vendors (first two 
bytes).

Hope this helps a little bit. My solution at the moment is the well known 
addition "if.netnames=0" in grub commandline.

So I can easyly change from eth* to enp* when this is recommended.

Best regards
