Hello my friends, 

I have AP aironet 1240ag , i tried to configure it but when i finished it doesn't work ,so i noted that there is an error with mac address , and as you can see there is no mac address or the mac address is "bia" and it's immpossible.

can you help me please to figure out the problem.

Thank you.

please see the screen shoots.

Your default gateway is "255.255.255.255"? This is NOT correct.

No because when open this page you have to wait while the access point pop up your configuration ,so i took the screen shoot befor. but the question is why the mac address is BIA instead of a normal mac address.
