Hello. having hard time with my enc28j60 small shield for arduino uno.
This is 3rd day pulling my hair.
I googled whole internet with no answer to fix my issue.
I have connected my
I have ethercad included and testDHCP shows only mac adress. my router does not dedect the enc28j60.
(enc28j60 is written on the pcb not on the chip)
my wiring is
gnd gnd
vcc 3.3v
cs pin 8
si pin 11
so pin 12
sck pin 13
with this wiring it never worked for me. I just changed wiring from cs to pin 10.
and boom, dhcp worked fine and I can create webserver and it worked fine.
today nothing changed it does not work anymore.
no matter what wiring diagram I use.
Wierd thing is with 3.3v and testdhc code. I get nothing
with 3.3v and with static ip code, I get nothing
with 5v and static IP, my router dedects the IP I gave it, but I cannot ping it still.
with 5v and DHCP I get nothing.
the backsoon code, with DHCP I get nothing I give it static IP and serial monitor outputs
[backSoon]
IP: 192.168.8.200
GW: 192.168.8.1
DNS: 0.0.0.0
but I cannot ping that IP, router shows it that that is the IP for arduino
with DHCP serial monitor only gives [backsoon] text.
I have tried many different cat5e and cat6 cables. does not matter.

Ideas?
It worked fine yesterday, but not today anymore.
