Recently I bought two DIR-655 A2 routers off fleabay, intending to use both of them only as gigabit switches and wireless APs (I already have a router).

Upon flashing both units to the latest 1.32NA firmware, configuring each one with a different LAN IP, and turning off DHCP server on both units, I plugged them into the same home LAN network. Everything seems to work flawlessly except that I cannot ping (times out) or get into the management page on one of the DIR-655. The other DIR655 lets me ping and login just fine.

Then, I found this:

Code: [Select]

C:\>arp -a

These are my DIR655's:
 192.168.1.252         00-03-64-00-01-24     dynamic <-- not responding to ping
 192.168.1.253         00-03-64-00-01-24     dynamic <-- responding pings OK


After Googling it seems that this MAC address is also reported by someone on DSLreports who was using a different d-link product and after flashing his got changed to the exact same LAN MAC as listed above.

Is this a known D-Link firmware BUG? Is there any fix available??

The device allows you to set a MAC address of your own choice (common for a router).
Setup->set manual internet connection-> bottom of page

Some ISPs can block (temporarily) new MAC's on a connection.
Using the one from the previous router will allow to keep the connection.
Probably the previous owner set the MAC address.

So I would change them

[davevt31]

Check the mac addresses againsts the sticker on the bottom of each unit.  They both should not have the same MAC.

Thank you for the tip but unfortunate that leads to another (bigger) problem -- the sticker with MAC address is missing from the bottom of both routers!

I can see the place at the lower left conner where the MAC address sticker is supposed to be, but nothing is there.

Could these routers be some of those clones proudly made in China? The routers got flashed with D-Link firmware alright. If I knew there were cloned D-Link routers I would have never bought them used off the flea market site!

Another strange thing, the FCC code showing on the back says DIR655A3 (which is the revision the seller advertised) but the firmware says Hardware: A1/A2. Smells fishy.
^--- Nevermind this, I'm read elsewhere that many versions of D-link firmware do not report the current hardware version. Since all the firmware flashes OK on the two units, the routers should be genuine D-link.

[davevt31]

Better get some flea powder.

Did they come in DLInk boxes, the MACs would also be on those.

[foxium]

davevt31, unfortunately they didn't come with boxes.

It seems like there is at least another person suffering from the same problem and got the exact same MAC mine did, but with another D-link product DGL4500:

http://www.dslreports.com/forum/r20802186-DGL4500-NEW-Firmware-110-Released

If this were a cloned router, the problem should be heavily reported elsewhere by those who purchased. But I was only able to find this one other report on the net.

May be it IS a firmware problem after all.

[davevt31]

Most people only run one router so the cloned MAC would not be an issue for them.  You can go into the Setup> Internet page and change one of the mac addresses and see if you can get through.  Its at the bottom of the page.

[foxium]

Thanks for trying to help davevt31. I've tried changing the WAN MAC (which changes OK) but it doesn't affect the LAN MAC. I've tried all 1.3x firmwares (even the latest 1.33NA beta code) but it doesn't change the MAC either.

The problem now is I have to unplug one of the 655 and flush arp cache in order to access the config page of the other's. I once thought it's due to hardware problems but someone from DSLreports received exactly the same MACs after flashing suggests that this problem is highly likely due to a defective firmware.

I guess waiting for D-link to realize and fix this problem are too much to expect. I'll probably throw away one (and possibly both) d-link routers. I just hate to do that cus I just bought them for a couple months. And correct me if I'm wrong, I don't think all DIR-655 shares the same LAN MAC, making it really weird.

At this point I'm very upset. I've never spent so much time dealing with a consumer router that's marketed as a premium product -- I shouldn't have to.

MACS should be in the status page.

This problem is apparently acknowledged by D-link for their DGL-4500 XTREME N GAMING ROUTER:

http://www.dlink.com/products/?pid=DGL-4500&tab=3


Firmware   1.12   8/07/2008
Revision Info:   ¤ Fixed upgrade FW, lose mac address.
¤ Prevents downgrade to 1.02.
¤ Follow Wi-Fi Cerits. N only has HT40 mode.
¤ MAC Address Filtering Fix.
¤ Wireless Schedule ADD tab change to "Add Schedule"



Apparently D-link is making a repeated mistake.

[foxium]

Sorry for bumping this myself. But I've found some more related information. Apparently D-link DID make a mistake in one of the firmware they released for DGL-4500 (fw 1.10) which they subsequently retracted.

It's highly possible that one of the currently released DIR-655 firmware is doing the same thing, causing the problem I'm experiencing.

D-link, please test your firmware seriously. I've written an e-mail to D-link support and a week ago I got a response saying that my question is being escalated to level 2 -- I'm still waiting.

Lycan, since you were aware of the exact same problem found in the DGL-4500 firmware, is it possible to incorporate similar fix to new DIR-655 firmwares?

I'm sure you already know about the mac-address problem and it giving everyone the same one of
WAN:
MAC Address : 00:03:64:00:01:23
LAN:
MAC Address : 00:03:64:00:01:24

We've pulled the 1.10 code because of issues reported here and in our internal CRM database.
We are working diligently on a correction for those that upgraded and can no longer use MAC filtering or are experiencing other firmware related issues.
We apologize for this inconvenience.

You can request an RMA, but we're expecting code as early as this week.
My guess is that RMA will take longer then that to just process. It's your call.
As for the MAC address issue, we are confident that we have a firmware fix that will put you back on-line asap.

[Cobra]

Those MACS are not the same as the last digit is different.

[foxium]

Cobra, LAN and WAN MACs are indeed off by one digit within each router. However, I have two DIR-655 routers and they share the same pair of LAN & WAN MACs (my router 1 has LAN MAC 00:03:64:00:01:24 and my router 2 has exactly the same LAN MAC).

This makes them impossible to use on the same network, it simply messes up the ARP table and causes all kind of connections problems.

[EddieZ]

Awaiting any more Double DIR MAC's, but it seems the devices you bought have been refurbished or faked...
