hello bro, I hope you are well i want to ask about a problem
this problem connects disconnect for a moment and back and this makes the signal onto the system slow and sometimes

wiring guide

ESP32 | NC | 22 | 19 | 21 | 26 | 25 | 27 | 17 | 23 | 18 | GND | 3V3

LAN8720 | NC | TX1 | TX0 | TX_EN | RX1 | RX0 | CRS | nINT/REFCLK | MDC | MDIO | GND | VCC

ethernet:
type: LAN8720
mdc_pin: GPIO23
mdio_pin: GPIO18
clk_mode: GPIO17_OUT
phy_addr: 1 # 0 or 1 for LAN8720

No one can respond to that. Please read How to help us help you - or How to ask a good question, particularly point 11.

Also you didn’t respond regarding what device you are using.

Did you wire the lan8720 yourself, or did you buy a board with it included?

If you wired it yourself, perhaps (likely) this is the problem:

If your Ethernet board is not designed with an ESP32 built in, it’s common to attempt to use flying leads, dupont wires, etc. to connect the Ethernet controller to the ESP32. This approach is likely to fail, however, as the Ethernet interface uses a high frequency clock signal that will not travel reliably over these types of connections.

If you bought a completed board with the lan8720 built in, then

is inadequate to help.

Also please post your yaml properly, as I already requested.

I bought it separately and connected it on my own using wires
If you connect the wires using tin welding, can it solve this problem?
or some Solutions? or replace the cables to solid wires with welding?

8

I don’t know.

I assume you mean soldering, not welding.

I wouldn’t attempt it at all, so someone else will need to advise on soldering such high frequency components.

In the meantime, given that you can’t be bothered fixing your yaml, I am out of here.
