Because WiFi is a bit more complicated than wired Ethernet. Getting all of the code to properly associate with access points does not look trivial. And attaching to a secured network with WPA is far more onerous.

Sorry for long absence - it took time to re-locate and settle in a new place (I moved from NY to CO during 2017 and still moving boxes around)

Thank you, I simply repeated everything from 2 years ago to make sure I don't forget to finish it in near future

For user from PC it will look like this:
Code: Select all
3F8h - register MR of W5100 (indirect mode flag and auto-increment flag)
3F9h - register IDM_AR0 of W5100 (most significant byte of the address)
3FAh - register IDM_AR1 of W5100 (least significant byte of the address)
3FBh - register IDM_DR of W5100 (data register to read/write in indirect mode)
3FCh - reserved for future
3FDh - reserved for future
3FEh - reserved for future
3FFh - reserved for future
More details about W5100:

(I'm not getting forum notifications ... yet another thing to debug.)
The WizNet looks like it has a TCP/IP stack built in. Can it be told to just send and receive raw packets? mTCP and other existing networking software just needs the ability to send and receive raw packets; they are not designed for use with things that offload the TCP part.

It looks like newer WizNET chips can do that - this one is not
For now it's just trying a concept - if it will work out well then we can try better approach
