I have a question about mac addresses and my router...
I have a linksys wireless router with dd-wrt firmware installed. The router is also my gateway. I have a few computers behind the router. Now, when I connect via wireless I use
iwlist wlan0 scan
and I find my essid with a certain mac address for the linksys router. I connect easily with
iwconfig wlan0 essid xxxx
iwconfig wlan0 ap xx:xx:xx:xx:xx:06
iwconfig wlan0 key xxxxx
However, when I check my arp cache I notice xx:xx:xx:xx:xx:04 as the mac address of my router. Why is the mac address last digit different?
