LAN port randomly freezing

[djsomi]

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
