I have two notebooks, one white and another that is red.
I want to connect them through their local adapters and share the internet connection of the red one that is received through WiFi. I could do the opposite, and share the white computer's internet connection through the cable.
I tried the following schemes:
white WiFi adapter disabled, red WiFi enabled and shared. And with both local adapters configurations on automatic;(which is recommended and taught by many tutorials online)
Same as before with static IP and the red one as the gateway of the white and the WiFi adapter of the red as gateway of the red PC;
I've tried several other combinations as I became hopeless to make it work, but I think those represent well the main possibilities.
As requested, the details, they are set to automatic, nothing interesting on the IP setting page, but here there is the fact they aren't in the same IP range(yes, I have the cross-cable and the direct one):
