I recently switch the firmware from Oleg to Openwrt
However, even I am not browsing website or using the internet, the "WAN" LED of the router always blink frequenctly.
Is that normal? I am using PPPoE to connect my ISP.

My nvram setting is below:
--------------------------------------------------
boardnum=asusX

boot_wait=on

Thanks your help,
but sorry to say, I have to rollback to the Oleg firmware because I dont know how to enable UPnP and my HP Printer in the Openwrt.

But I woluld like to know the setting of PPPoE in Openwrt. At fisrt, my router cannot connect to the internet, but after adding wan_device=eth1, it can connect and the wan led begin to blink.

I am using WL500g.
