Wifi is not working on two of my boards 3

I have some tests on the bug boards today.

Address can not be assigned because of HWAddr is not correct. HWAddr is hardware mac address.

It is FF:FF:FF:FF:FF:FF

eth0 Link encap:Ethernet HWaddr FF:FF:FF:FF:FF:FF

Use ifconfig to setup that address and bring up eth0 success.

ifconfig eth0 hw ether 46:9B:94:0A:E6:71
ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up
ifconfig eth0.1 hw ether 46:9B:94:0A:E6:71
ifconfig eth0.1 192.168.1.101 netmask 255.255.255.0 up
ifconfig eth0.2 hw ether 46:9B:94:0A:E6:71
ifconfig eth0.2 192.168.1.102 netmask 255.255.255.0 up

And now in ifconfig ethernets are all up.

ifconfig wlan0 192.168.1.103 netmask 255.255.255.0

setup ip for wlan0.

Now the ifconfig result is same as the normal one. But iw dev wlan0 scan has nothing returned, wireless module still dose not work.

Another try is to call:

/etc/init.d/firewall stop
/etc/init.d/firewall disable

firewall is stopped, still dose not work.

 

This bug is not easy to locate now. I guess this must have some connection with hardware, now I have to check the ethernet driver to see what will cause it failed to start. Lucky me still have one board work. It will be a long way to find out the problem.
