WNDR3700v5 LED not working

Hello,

sorry if this is not inthe good place but I'm new and a bit lost in the forum. Recently i've installed "LuCI lede-17.01 branch (git-17.100.70571-29fabe2) / LEDE Reboot 17.01.1 r3316-7eb58cf109" and everythin is working OK but I miss the LED lights to monitor the ON/OFF, wireless and USB activity or state. At the moment only the 4 LAN ports are working.

For solving this little problem I dont know if I have to wait for the next release, install aditional package or packages or even configure in the "System/LED configuration" page in LUCI.

Anybody has some experience with this particular subject to point me in the right direction?

thanks!
