LED link on WAN port ON when disconnect cable link ( not change to OFF, always ON).

 

Help me how to fix the problem 

Only on WAN port - which kernel, legacy or vanilla or on both?

WAN port

 

There is no WAN port on Lamobo R1, that's just another LAN port that is called differently. The Lamobo R1 is not a router but a dumb switchboard instead. In case you want to use it as router stop now and replace it with something less insecure: http://linux-sunxi.org/Lamobo_R1#Security_Implications

I tested with last version vanilla.

1)  WAN disconect cab link

     - power on

     - R1 boot reset WAN + LAN port

     - Problem : WAN LED green ON, 4 ports LAN  LED green OFF

2) WAN connected cab link

     - WAN : LED green and yellow blink when TX data

     - Problem : WAN disconect cab link, WAN LED green ON not OFF

 

I think LED green ON when connected cab link to WAN or LAN, OFF when disconnect.
