Archer c7 v5(EU)
The LAN cable is connected to LAN1, LAN2, but the light is on LAN1-LAN4. LAN cable
not connected to LAN1-LAN4 light illuminates LAN1, LAN2.
how to fix it?
determined by gpio enable, gpio disable
gpio 1 = led wps
gpio 6 = led power
gpio 7 = led usb
gpio 8 = led lan 1
gpio 15 = led lan 4
gpio 16 = led lan 3
gpio 17 = led lan 2
gpio 21 = led lan wan
The LEDs are a pretty unreliable indicator on many of the DD-WRT builds for a lot of devices as they are different between devices and can be difficult if not impossible to control. For the status of LAN/WAN ports it is better, and often easier, to check the colours on the “Link Status” line on the Setup / VLANs tab
From memory, green = gigabit, yellow = 10/100, and red = not connected
swconfig dev switch0 show |grep "port:5" | awk '{ if ($3=="link:down") system("gpio enable 15") }'
swconfig dev switch0 show |grep "port:4" | awk '{ if ($3=="link:down") system("gpio enable 16") }'
