KC868-COLB - How to Connect by Ethernet and DHCP - upstream - 04-02-2026
I want to connect the KC868-COLB to my own network (I have router and DHCP server) with ethernet only. The KC868 should get a DHCP lease from our server OR I need to set the static IP somewhere.
I do not want to use WiFi.
I tried to follow instructions here and I am not successful.
Is TCP Client mode what I need?
When I hold down "Ethernet Mode" button the LED cycles through only 2 options:
1. yellow and white LED
2. yellow, white and blue LED
I can connect to server via WiFi (ssid LPT230) but I do not know if I can change settings for Ethernet.
I have a video of the LEDs but I cannot attach video files here.
Thank you.

Hold on "ethernet" button, when the [yellow and white LED] all is ON, release it, then work mode in “UDP” and IP by DHCP mode.
now your controller maybe is STATIC ip 192.168.1.200

Oh thank you that worked.
Can I turn off the Wifi somehow?

just set wifi to STA mode. it will not show the wifi ssid: LPT230

Okay thank you. Now I have a new problem.
I did successfuly configure ethernet with static ip one time. Then I was playing with some settings (I don't remember what) and I broke it.
For some reason I can no longer connect to Ethernet.
I press and hold the Ethernet Mode button until the lights are Yellow and White.
Then I wait.
Then I connect ethernet, and when I do that, the Yellow and Blue lights turn on.
I noticed that when the ethernet cable is connected you cannot change the Ethernet Mode, which is probably good.
Anyway I already tried to Restore to Factory Setting (from wifi interface) and now I still cannot get the ethernet to work.
I cannot ping 192.168.1.200 and there is not web access either. My unifi switch also said for a moment that it connected with ip 192.168.1.100.
How can I fix this now?

i think you can re download firmware again.
