I have a wireless router (dlink DIR-615) and have locked it down based on MAC address. Generally this is working well however I have just tried connecting an iPhone to the access point and get an error that the MAC address is invalid. The only difference I can see is that the first two digits for the iPhone are 04 - all the other addresses start with 00.

When I turn the MAC address validation off the iPhone connects just fine. So I tried to "import" the MAC address once it had connected, but same result.

Any ideas?

Cheers
Rob

DLink? Sorry, this is your problem...

Settings > General > About

Scroll down to Wi-Fi address.

Put that in your router. Done.

If it doesn't work, see freitasm's explanation.

Te problem is that my router says the MAC address is invalid - I am guessing due to it starting with "04" instead of "00"

I would try a firmware update, out of interest I checked here

http://en.wikipedia.org/wiki/MAC_address for the MAC Address standard and here http://standards.ieee.org/cgi-bin/ouisearch and Apple have been allocated 04-1E-64 among others for MAC Addresses.

You could spoof your MAC address here http://www.hackint0sh.org/f127/12244.htm if you can't upgrade the firmware or it doesn't work.

But I would give up on locking down by MAC address and just turn on WPA/WPA2 if you can as this is more secure, otherwise someone can just watch mac addresses flow across the network then set their device to one of these mac addresses and away they go.

Yes use WPA2 (or WPA if you have other older devices) with AES encryption and a PSK ("pre shared key" aka password).

MAC address restriction is not very secure at all.

This is a know issue by DLINK. Actually there is been a bug on this specific model of router.
To solve this problem just download the latest firmware update at

http://www.dlink.ca/products/?tab=3&pid=DIR-615&rev=DIR-615_revC

You probably have the version 3.10NA and need to upgrade to 3.11NA.

Good luck

If its for use in NZ you need the correct AU/NZ firmware from http://www.dlink.com.au/tech/Default.asp. The upgrades don't mention any MAC address fixes.
