Thank you for your prompt reply... @felmue
The example you posted [https://community.m5stack.com/topic/4376/] helped me get started with this module.
#UiFlow built-in sample was not a core2 compatible screen and did not work. :-(
I tried [lan.get_if_config()] you suggested with the shell of [Windows 10, Thonny(v4.0.0.b3)].
While doing other trial and error, It seems that [libs/ethernet/wiznet5k.py] and [libs/ethernet/wiznet5k_dhcp.py] were running behind [lan = module.get(module.LANBASE)].
If we can operate here directly..., can't you read [libs/ethernet/wiznet5k.py]? :-<
Thank you,
