Newbie: Can someone clone your mac address

Yes. And yes even if you are using WEP. WEP does not encrypt MAC addresses.

Yes. If the intruder uses the same MAC address as you, you would get a message box on your screen, being Microsoft generated, it's meaning is not obvious ! If he uses it, when you do not, you would have to examine the logs on your router to discover it. Regards, Martin

Does your wireless support WPA security? or WEP? If WEP is all you have use it with open authentication. WEP is not foolproof but it can make it harder for someone to get on your internet. So even if they know your mac address they will also have to figure out your wep key. It takes 5 to 10 meg of data to crack a wep key. WPA is not know to be crackable.......yet

Thanks for the correction.

nonsensical)

Taking a moment's reflection, Airhead mused: | | It takes 5 to 10 meg of data to crack a wep key.

Actually it takes 5 to 10 million packets of data to crack a WEP key.

WPA-PSK is still vulnerable to dictionary based attacks (as is WEP) which is why it is recommended to you a strong (long and nonsensical) passphrase.

He would he know what MAC address i have. What would I look for in the logs?

I have them all, but there is a bug in the firmware (waiting for an update as the most current update isnt any good) so I cant use anything other than WEP as I will drop connections. My ISP says I dont need a firewall since I have my router, but D-Link says the more security features I have enabled on my router, the slower the connection. Right now, there are connection issues with my ISP so and drop in speed is clearly noticable.
