Posted: Sun Dec 02, 2007 20:17 Post subject: [SOLVED]How to change wireless mac addresses of Fonera???

Hi to all.

I have a big problem.

I successfully installed the last dd-wrt release on Fonera but now I'm not able to change the defaults mac addresses.
I modified with the following command:

nvram set et0macaddr=00:05:BB:ED:AF:8C
nvram set lan_hwaddr=00:05:BB:ED:AF:8C
nvram set ath0_hwaddr=00:05:BB:ED:AF:8D
nvram set wl0_hwaddr=00:05:BB:ED:AF:8D
nvram commit

When I go in to web interface after reboot it seems good:

Router
Router Name
DD-WRT
Router Model
Fonera 2100/2200
LAN MAC
00:05:BB:ED:AF:8C
WAN MAC

Wireless MAC
00:05:BB:ED:AF:8D
WAN IP
Disabled
LAN IP
192.168.0.1

But if i try to connect with a wirelss client the wirless mac it's always the original default.

It seems that the default wirless mac it's write into the kernel or in hadcoded way.

Infact if I lunch the ifconfig command

Infact if i check the device value it's setted to original:

cat /sys/devices/virtual/net/eth0/address

ORIGINAL MAC

cat /sys/devices/virtual/net/ath0/address

ORIGINAL MAC

From web i setted the starup script command with nvram but nevere changed.

I saw in the nvram settings these variables:

ath0_macmode1=disabled
wl_macmode=disabled
wl0_macmode=disabled
wl_macmode1=disabled
ath0_macmode=disabled

What they mean??

Could someone help me??

Thank u in advance!!!!!!!

It is probably stored in the bootloader, you may need jtag cable.

I guess if the bootloader is on a partition, you probably will be able to retrieve its contents using a dd command, modify the contents, then use the dd command to upload to the partition to see if the MAC Addresses have changed. _________________ Mazi UK non-geo DID #: +447031942574

I'm thinking to use the redboot prompt.

But i'm not sure that in dd-wrt installed it works....

Normaly it works in installation/flashing phase, after the reboot the first 10 second the fon dd-wrt listen on special tcp port .

I'll try with finally dd-wrt installation ..to see if I'll able to go in telnet in redboot.

Try hex editing the bootloader (VERY VERY CAREFULLY!).

I believe the atheros calibration and mac addresses are stored in an area marked off as not accessible by the bootloader.

I agree with you.

But I think that ther's must be a way to change the default mac address, it's not possibile that thers'not.

Is there some dd-wrt developper that can help me??

I remeber that when I installed the open-wrt on the linksys devices by default open-wrt changed the default mac with one that was always the same for all.

I saw there were changes in SVN regarding MAC's. Maybe you should check it out: especially the changes on 12/05/2007 http://svn.dd-wrt.com:8000/dd-wrt/timeline

No news from the ticket!!

I installed the new RC6.1 firmware but the problem remain the same.

I changed other values in nvram but nothing changed!!

nvram set def_whwaddr="00:01:02:03:04:2D"
nvram set wl_ap_mac="00:01:02:03:04:2D"
nvram set def_whwaddr="00:01:02:03:04:2D"
nvram set et0macaddr="00:01:02:03:04:2C"
nvram set lan_hwaddr="00:01:02:03:04:2C"
nvram set il0macaddr="00:01:02:03:04:2D"
nvram set ath0_hwaddr="00:01:02:03:04:2D"
nvram set wl0_hwaddr="00:01:02:03:04:2D"
nvram set et0macaddr="00:01:02:03:04:2C"
nvram set lan_hwaddr="00:01:02:03:04:2C"
nvram set ath0_hwaddr="00:01:02:03:04:2D"
nvram set wl0_hwaddr="00:01:02:03:04:2D"
nvram set wl_hwaddr="00:01:02:03:04:2D"
nvram set wl_active_mac=00:01:02:03:04:2D"
nvram commit

When i try to connect with a wireless client the MAC ADDRESS shown is the original!!

My gooooddddd!!!!!

these are the getWANMac, getLANMac, getWirelesMac function that get the mac adress:

Code:

   }

      char *getLANMac (void)
      {
         unsigned char mac[20];

         strcpy (mac, nvram_safe_get ("et0macaddr"));

         if (nvram_match ("port_swap", "1"))
         {
         if (strlen(nvram_safe_get ("et1macaddr")) != 0) //safe: maybe et1macaddr not there?
         {
         strcpy (mac, nvram_safe_get ("et1macaddr"));
         }
         else
         {
         MAC_ADD(mac); //et0macaddr +1
         }
         }

         return mac;
      }

      char *getWirelessMac (void)
      {
         unsigned char mac[20];

         if (strlen(nvram_safe_get ("il0macaddr")) != 0)
         {
         strcpy (mac, nvram_safe_get ("il0macaddr"));
         }
         else
         {
         if (nvram_match ("port_swap", "1"))
         {
         if (strlen(nvram_safe_get ("et1macaddr")) != 0) //safe: maybe et1macaddr not there?
         {
         strcpy (mac, nvram_safe_get ("et1macaddr"));
         MAC_ADD (mac); //et1macaddr +2
         MAC_ADD (mac);
         }
         else
         {
         strcpy (mac, nvram_safe_get ("et0macaddr"));
         MAC_ADD (mac); //et0macaddr +3
         MAC_ADD (mac);
         MAC_ADD (mac);
         }
         }
         else
         {
         strcpy (mac, nvram_safe_get ("et0macaddr"));
         MAC_ADD (mac); //et0macaddr +2
         MAC_ADD (mac);
         }
         }

         return mac;
      }

      char *getWANMac (void)
      {
         unsigned char mac[20];

         strcpy (mac, nvram_safe_get ("et0macaddr"));
         MAC_ADD (mac); //et0macaddr +1

         if (nvram_match ("port_swap", "1"))
         {
         if (strlen(nvram_safe_get ("et1macaddr")) != 0) //safe: maybe et1macaddr not there?
         {
         strcpy (mac, nvram_safe_get ("et1macaddr"));
         MAC_ADD (mac); //et1macaddr +1
         }
         else
         {
         MAC_ADD (mac); //et0macaddr +2
         }
         }

         return mac;
      }

so the vairable to change are :

et0macaddr
il0macaddr

But after editing them in nvram, never changed!!!
