Hello guys,
I have been trying to use 1 router and 2 APs on a network. Both the APs are N13U B1s on DDWRT. Both the APs won't co-exist on the same network because of LAN/WAN Mac ID clashes. However their WLAN Mac ids are different.
I have tried the mac clone options
1) The display doesn't change.
2) On checking the actual mac id of the device, neither does the mac id in the mac clone area is shown.
Does any one know how to ensure that two or more DDWRT N13Us can peacefully co-exist on a network? Any help with changing their MAC ids for good?
Thanks for the links. I was able to make a part of it work before I hit a new problem.
Using:
nvram set wan_hwaddr=00:0C:43:45:47:15
nvram set lan_hwaddr=00:0C:43:45:47:16
nvram set et0macaddr=00:0C:43:45:47:16
nvram set et0macaddr_safe=00:0C:43:45:47:16
nvram commit
gpio disable 14
I was able to change the mac ids displayed on the router admin panel. However, they still seem to be reporting the stock mac id to other devices.

In my current config I am using an ASUS RTN66U (stock) as the modem/router and the 2 DDWRT N13U B1s as Access Points.
I am attaching three images. One each from each of the machines to show up how the 2 DDWRTs are still reporting the same stock MAC id to the modem/router.
im running a LAMP server behind a router that is dd-wrt pre sp2 beta 21061, configure client bridge (routed), everything works fine except when i try to ssh from internet to my lamp server, i can view web server send/receive email https web server everything except ssh. ive done tcpdump and connected and everythign looks fine, its when i arp-scan that i get a DUP msg where dd-wrt is somehow throwing an extra <IP> <MAC>, and that is what is messing up my ssh, thats only possible thing it could be, ive had such a horrible time with this so far, I am up to the last nposts part and have tweaked it
i='nvram get wl0_hwaddr'
ifconfig bro hw ether $i
nvram set lan_hwaddr='00:00:00:00:00:01'
nvram set et0macaddr='00:00:00:00:00:02'
nvram set wan_hwaddr='00:00:00:00:00:03'
now this sets wlan to your br0 (bridged interface?)
and than you can randomize the next 3 MAC's
I can connect to dd-wrt router, the host router, all comps on network and when i ping them there are no DUP pings like before if i were to ping <DD-WRT> iot would DUP ping, but now when i ping google.com i get a DUP, and im figuring changing them all to diff MACs is what creates the not able to connect with DD-WRT , hard reset scenario. I will keep experimenting and post back, very tricky indeed!
nvram only changes whats displayed to user on web gui, (maybe telnet as well?) doesnt change whats being actually reported on network to hardware which makes sense if this is linux based, idk if its possible to do a client bridge (routed) without having it set up this way (having a DUP in arp-scan, DUP ping when you ping <IP of DD-WRT client bridge router>), can anyone confirm this?
