Hello,
I have found similar topic on this forum, but solution doesnt work for me.
My question is. How to get W5100 Mini ethernet module (the red one) work on arduino nano (or Mega).
If I connect it to Arduino UNO, everything works like a charm. If I connect it to Arduino MEGA2560 or nano it always says Failed to configure Ethernet using DHCP (I have example sketch uploaded).
I have tried to connect it like this:
SCK - 13
MISO - 12
MOSI - 11
SS - 10
No success (neither mega or nano)
I then tried 50-53 pins on mega. And even 10 as SS on mega instead of 53
Ive also tried ISCP headers.
I tried to connect RST pin of the module to +5V. Or to RST on arduino
Still cant connect.
I can connect with Ethernet shield, so there cant be problem with my network. And as Ive said, the module works on UNO.
Please any ideas?
And Ive also tried to power it from external 5V/1A source, and yes Ive connected grounds.
