I have the same problem. It also appears that despite the rule exists, I can't change real NIC name in the rule, i.e. when I change "eth1" to e.g. "wlan1", it doesn't take effect. Seems the rule is ignored. It should be noted that the two rules listed in original report are about the same device, but lower one is with proprietary driver and upper one is (AFAIU) with free one.

It looks like you have a Broadcom wireless NIC as do I. I am seeing the same problem. It's likely this is related to the Broadcom driver in some way. Wireless still works but the readout of ifconfig is extremely confusing.

I had the same issue with my HP Mini 110 3101SD with Ubuntu 12.04.2 (latest updates).

Not only was the wireless connection referred to as eth1, but also as the original poster wrote " share [...] connection not establish other computer." which i understand to refer to the inability to access the laptop from another computer (network settings like subnet mask and workgroup all checked and ok) not even using the 'ping' command.

After trying this answer ;
http://askubuntu.com/a/38700
about doing something with the Broadcom driver for the wireless card, not only does the wireless connection show up correctly as wlan0, but also i can now easily connect from another (Ubuntu) machine.

Hope it helps.
