change network device name

[mese79]

Hi
I have hp tm2 laptop with two network adaptor(wired and wireless):

#lshw -class network
*-network               
       description: Ethernet interface
       product: RTL8111/8168B PCI Express Gigabit Ethernet controller
       vendor: Realtek Semiconductor Co., Ltd.
       physical id: 0
       bus info: pci@0000:01:00.0
       logical name: em1
       ...
  *-network
       description: Wireless interface
       product: BCM4313 802.11b/g/n Wireless LAN Controller
       vendor: Broadcom Corporation
       physical id: 0
       bus info: pci@0000:02:00.0
       logical name: eth0
       ...

#netstat -i

Kernel Interface table
Iface      MTU    RX-OK RX-ERR RX-DRP RX-OVR    TX-OK TX-ERR TX-DRP TX-OVR Flg
em1       1500        0      0      0 0             0      0      0      0 BMU
eth0      1500     2386      1      0 0          2655      3      0      0 BMRU
lo       16436     8174      0      0 0          8174      0      0      0 LRU

I use some tools like vnstat and ntop to monitor my network bandwidth, but i have a weird problem with my network devices:
Every time i restart my laptop, the wireless network device name was changed(switched between eth0 & eth1)!!
So i can't monitor my network properly and after each boot i should check device name and restart those monitoring tools with new device name.
Now is there any way to set network device name manually?
I'm using fedora 17 (3.4.2-4.fc17.x86_64).
Thanks.

Well I found this and follow the first step:
Fedora 16 ethernet port naming "secrets" p1* to eth*
It seems my problem was solved. but i couldn't find the file '/etc/udev/rules.d/70-persistent-net.rules' or anything related to network in /etc/udev/rules.d/ . so i just do step one and then my wireless lan became eth0 and embed lan(em0) became eth1.

***
Sorry, it wasn't solved
Today it happens again, and my wireless interface was changed from eth0 to eth1.
I don't know what else todo to fix this.
