I have a D-Link DIR-825 ver 2.10. I just got an iPod Touch 3rd gen. First, I went into D-Link's "Network Filter" tab to add my iPod's MAC address to my list of computers. When I tried to save changes, I got a message that the MAC address was invalid (I noticed that my iPod's MAC address begins with 2 digits, while all my other devices have addresses that begin with 00). On the advice of D-Link tech support, I tried turning MAC filtering off to see if my iPod would connect that way, and it was -- I was able to login with my security key password. I went back into the "Network Filter" tab, and when I pulled down one of the listed menus, it said "iPod" along with the MAC address of the iPod. But when I tried to enter the MAC address where the addresses go, I again got the same "MAC address invalid" message.

The D-Link tech support said I should call Apple, since none of my other devices were having problems connecting, so it must be an issue with the iPod. Apple tech support had me "restore" the iPod's factory settings, implying that that would give me a new MAC number, but nothing changed. They sent me back to D-Link, saying that it must be a router issue. I am starting to come to the (very disappointing) conclusion that my iPod cannot be used with my D-Link router as long as I want to use MAC filtering. Is this true? Anything else I can try?

Without seeing the MAC address, I can't be 100% sure, but
I think it very likely that D-Link's rules for validating a MAC
address are wrong.  About all they should be checking is that
all the characters are valid hexadecimal digits and that
it is of the form of a unicast address and not a broadcast address;
and I think that's a single bit, the low order of the first byte as
you enter them (the last digit of the first byte should be even or
a, c, or e - which are also even in base 16).

If you really really want to use MAC address filtering (and I don't
blame you for that), I'm pretty sure that if you jailbreak your
iPod Touch, you could create a launchd plist file that would set the
MAC address to something that your router will accept.  Mine
(1st gen) is jailbroken, and I think I can set the MAC address,
however I haven't set up anything to do that automatically when
it boots (since I don't have that problem).  I could probably figure
it out, but whether I could explain it is another story...

How ironic -- jailbreak the iPod to keep the rest of the network secure! I'm not sure how willing I am to do that. I just feel a little cheated that I paid $350 for a device that can only be fully functional if I am willing to compromise security. And if you're right, then D-Link should fix the firmware, since I can't be the only customer who has run into this issue.

I believe, if you look through this forum, you will find that there is a problem with MAC address filtering in the DIR-825.  I don't remember the exact problem, but I believe it had to do with the MAC address starting with something other than 00:

I also believe a recent firmware update may have corrected the problem.


Why not just use WPA-2 security? As far as I know, it's as secure as MAC address filtering.  Is this network in your home?  Do you live in an area where people are always trying to hack into your network?  I've been using WPA-2 security for years, both at home and at work, and have had no problems with it.

I also had this problem last night when trying to connect my new netbook to the router. The Mac address started with 90:

This was fixed by installing the new firmware 2.03N from dlink website

Ok, I'm running 2.03NA too, and I just changed the MAC address on
my iPod touch (after first adding the new MAC address to the network
filter list on the router) to begin with the highest-numbered Apple OID
that I could find on
http://standards.ieee.org/regauth/oui/oui.txt
which is f8:1e:df  (previously it began with 00:1e:52).  That worked
just fine - the router gave me no trouble entering that.  So maybe
2.03NA will help.

It hasn't been painless for everyone though, as you can see in other
threads...so you can roll the dice and make your choice...
