LAN port randomly freezing

[djsomi]

Hi All,

I have an A16S board, which has a problem. LAN is randomly freezing, board itself keep functional, but network is going down.
Ethernet cable replug solves the issue. (or rebooting the unit)

What can be the reason behind? Makes my automations really unstable.


Thank you in advance,

Zoltan

do you use ESPHome or KCS firmware?
can you change a ethernet cable and router's port.

I got a feeling that the board collect some voltage spikes from the electrical system. I already grounded the din rail, it helped a little, but randomly still happens. 
I'll try to swap cable and switchport, maybe I should use CAT6 shielded cable?

Its on ESPHome, LAN config is the folllowing:

Code:

# Example configuration entry
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0

CAT5 cable is OK. i think you can use a separate power supply for KC868-A16S for testing.
