You can modify MAC address under Adapter mode by following steps:
1.Enter Advanced Setting page, System Setup->Operation Mode, choose Operation Mode as Home Gateway;
2.Enter Advanced Setting page, Wireless->Advanced, choose Mode as Adapter;
3.In Quick Setup page, Current Mode will display Gateway-Adapter;
4.Enter Advanced Setting page, IP Config->WAN&LAN, fill in desired wireless MAC address in MAC Address field.
Attention: The MAC address filled should not be same as LAN PC’s. That is, you need to change LAN PC's MAC address
after copying it to WL-330gE configuration interface. This method is not really MAC cloning but allowing users to modify
the MAC address sent out by the device.
