** Summary changed:
- Wireless PCI device MAC address changes
+ 1814:0301 Wireless PCI device MAC address changes
** Tags added: kernel-wifi
** Description changed:
I have just installed Ubuntu 9.10 and have a Edimax EW-7128G wireless
PCI adapter
The MAC address and device name change between reboots, e.g.:
wlan0 00:1f:1f:51:7a:56
wlan1 00:1f:1f:53:7a:56
wlan2 00:1f:1f:43:7a:56
The MAC address change is making it impossible to, for example, control
access to my home network using MAC filtering.

+ WORKAROUND: grab the WIreless PCI card "device" and "vendor" IDs using lspci
-nn
+ add a rule to /etc/udev/rules.d/70-persistent-net.rules that reads:
+
+ SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{vendor}=="0x[vendor_id]",
+ ATTRS{device}=="0x[device_id]", NAME="wlan0"
+
+ (Where [vendor_id] and [device_id] are the IDs you picked up from lspci)
+
+ This ensures that the card is always wlan0.
+
+ Then I have written a script that runs at boot which assigns the desired MAC
address to wlan0:
+ ifconfig wlan0 down
+ ifconfig wlan0 hw ether ma:ca:dd:re:ss
+ iwconfig wlan0 up
