I need to share my wireless internet connection (on an Ubuntu laptop) with a RasPi connected to the laptop by ethernet.
Everything works fine by configuring eth0 as "Shared to Other Computers" (documented in many places, for example here).
Using this setup, my IP address when connected to the RasPi is
10.42.0.1. The RasPi picks up another address in that subnet. Everything works great!

wlan0 configuration when running
ifconfig, I'm unable to access the internet (presumably my laptop is trying to use
eth0 instead of

eth0 to use a specific IP address when configured with "Shared to Other Computers"
I'm trying to set up simple instructions for other users, so if possible I'd like to avoid any manual
