MAC address change

[chigo58]

Dear all,

I am attempting to change the mac address of the wifi interface using the traditional way of editing the /etc/config/wireless file and adding the option macaddr 'xx:xx:xx:xx:xx:73' line under 'radio0'.

The reason for this is that the router is connected as a WIFI client to my ISP and i wish to clone my MBP MAC address to the router.

Once I apply the change and reboot the router, the interface gets disabled and status is 'n/an/a'.

Can someone help me get this right?

Hi,

i know this thread is pretty old but I figured out how it works.

1. Connect to SSH

2. Install macchanger:

Code: Select all

opkg update

Code: Select all

opkg install macchanger

3. Disable Wifi Interface

Code: Select all

wifi down

4. Change MAC

For a random address:

Code: Select all

macchanger wifi0 -A

for a custom address:

Code: Select all

macchanger wifi0 -m BC:F4:11:6C:BC:58

5. Enable Wifi Interface again

Code: Select all

wifi up

6. Renew DHCP (via Webinterface for example)

Tested on Version 1.2.5 with FON2100

With the commands from 3. to 5. you could write a script to set the mac address at every boot

Have a look at:

https://wiki.openwrt.org/doc/uci/wireless

It seems like you tried to edit the wifi-device configuration, which can't be used for changing the mac address:

macaddr MAC address yes/no (autodetected) Specifies the radio adapter associated to this section, it is not used to change the device mac but to identify the underlying interface.

You have to edit the wifi-iface Part to specify a custom mac address:

macaddr mac address no (hostapd/driver default) Overrides the MAC address used for the wifi interface.

option 'macaddr' '54:e6:fc:af:3b:1e'

for example.

I hope this helps too.
