Been into Luci and in the System->LED Configuration section there are a number of possible Trigger codes that can be set for WLAN2G & WLAN5G.
Is it possible to use the 2G & 5G LED lights to show when Tx/Rx is being utilised on WAN & LAN ??
Something like this - WLAN5G LED = WAN Tx/Rx and WLAN2G LED = LAN Tx/Rx.
In effect use the 2G & 5G LEDs to signal when traffic is going to/coming from the relevant port.
*** No WiFi, all hardwired with Cat6 cable everywhere *** so can use LEDs for other purposes
