You want the WAN MAC listed physically on the bottom of your WRT3200ACM (a white sticker).

Log in to the DD-WRT Web GUI control panel. Setup: MAC Address Clone: MAC Clone set to Enable.

Enter the WAN MAC address found on the bottom of your Router in the field labeled Clone WAN MAC.

Save. Apply. Apply again for good measure. Reboot Router.


Edit: I found another thread with the same problem on WRT1900ACS. There may be a problem with recent builds of DD-WRT.

Try resetting to factory default settings in DD-WRT's Web GUI under the Administration Tab.

Have you tried powering on the modem first, then 5 minutes later powering on the router? Maybe try the reverse order too, router first then modem.

Lastly, try power cycling both devices with the ethernet cable between them disconnected then five minutes later connect the ethernet again.


You may have to use an earlier known working build of DD-WRT for now.

If you want to test that theory, go back to June 11 build r40009 with a reset to default settings.

Here's the http download in case your browser has issues with ftp, but I highly recommend Waterfox or Pale Moon.

06-11-2019 r40009 for wrt3200acm

i assume you've tried different DD-WRT builds? Or are you flashing the same build each time when you've returned back to stock?
I would try a build from early Feb 19, before they started with lots of changes.

Yes, if you are going back to February use 02-06-2019 r38581 for wrt3200acm.

was this router supplied by your ISP?

Then the mac address shouldn't make any difference what so ever.
i am at a loss as to why you're not getting an IP from your modem after flashing. Hopefully someone else can help you further.

Hi guys
I just bought WRT3200ACM, last week.
I have Fiber connection, there is no off//reset switch on this connection, just strait female Ethernet.
My old Router provided by ISP and it's working. (strait connection with other router//pc//laptop all works)
WRT3200ACM working too with the Linksys latest Firmware.
The problem is the custom firmwars DD-WRT//openwrt, after flashing DD-WRT or OpenWRT, the router wont connect to the internet through the direct connection but working if i connect it to the Lan of the old router or switch.
I did research whole the internet, seems no one could fix this issue.
1. Change//clone//spoof Mac address, useless.
2. Static IP: add manual IP//DNS// etc: useless

The question is, Is there any fix for this or I have to return it back until I got return policy door's open???

Any new help//suggestions, please don't bother with old sugestions I did every thing. Flash it 1000 times to older newer firmware of dd-wrt wont help.

Thanks in advance

Which build(s) have you tried? Please don't use the router database, especially avoid build r40559.

Does your ISP do NAT already for you, before it reaches your router? Does your ISP have any requirements?

Are you sure you cloned the WAN MAC address? It's easy to confuse LAN, WAN, or each radio's MAC addresses as they are usually incremental.

Hi, thanks for replying,
I only have one Fiber connection so I use one router connecting to it.
When I connect a laptop directly to the fiber I get ip that starts with 92.xx.xx. I believe it is a public ip. Then through the old router 192.xx.xx.
My ISP uses auto dhcp config, they told me the connection is plug and play. It's working with all kinds of router and computer that I have at home.
I cloned mac address by using the old router//pc mac//wrt3200acm mac// in the clone mac sections// it just won't get internet.
I used the latest firmware from betas//ftp links 2019 all from 31 of January to 10th of December. Non of them working.

Why it's working with Linksys firmware not dd-wrt or openwrt!?

🤔 I don't get it, what's the problem?
