ESP32-W5500 Webclient and Webserver not working

[Sireevenkat]

Hi,
I am using ESP32 Dev Module with W5500.I tried Webclient and webserver example but it's not working.

Starting WebServer on ESP32 with W5x00 using Ethernet_Generic Library with Large Buffer
Ethernet_Generic v2.3.1
[ETG] Default SPI pinout:
[ETG] MOSI: 23
[ETG] MISO: 19
[ETG] SCK: 18
[ETG] SS: 5
[ETG] =========================
[ETG] ESP32 setCsPin: 5        
[ETG] W5100 init, using SS_PIN_DEFAULT = 22 , new ss_pin =  10 , W5100Class::ss_pin =  5
[ETG] Chip is W5500
[ETG] W5100::init: W5500, SSIZE = 8192
[ETG] Currently Used SPI pinout:
[ETG] MOSI: 23
[ETG] MISO: 19
[ETG] SCK: 18
[ETG] SS: 5
[ETG] ========================= 
Using mac index = 1
Connected! IP address: 0.0.0.0 
Speed: 100 MB, Duplex: FULL DUPLEX, Link status: LINK

Sometimes It is working properly but sometimes I am getting as above.
I tried with Arduino UNO with W5500.I am getting same problem.
Can you help me to resolve the issue.

Hi @Sireevenkat

I'm just tested and everything is OK with my ESP32_DEV, W5500, Arduino IDE v1.8.19 and ESP32 core v2.0.4

This seems there must be some problem with either your W5500, wirings, etc.

As this is not a bug of this library, I'm closing this now.

Good Luck,
