Ok.
But traceroute does not work.
Can I make one to be automatically disabled when the other one connects? They are on the same network, it makes no sense to me. Not useful.
Why do you think traceroute doesn't work? Also, the interface with the lowest metric (Ethernet) will be used. Why is it necessary to shut down WiFi?
To save power.
- Ethernet uses considerably more power than wireless
It is usually the other way around. Either way, having both powered requires more power than powering only one.
Wireless power consumption: Intel, 2010: http://www.inf.ed.ac.uk/teaching/courses/cn/papers/halperin-hotpower10.pdf Cypress, 2017: http://www.cypress.com/file/298216/download
Ethernet power consumption: Intel, 2008: www.ieee802.org/3/az/public/jan08/hays_01_0108.pdf
Those are interesting papers. The Ethernet one seems to predate IEEE/802.3az, though.
-> Conclusion: If your equipment supports EEE/802.3az, ethernet comes close, if not ethernet is significantly worse.
Which is around for a while so I would expect most recent devices to support it. There were those "Green Ethernet" fake stickers on everything a few years back. Anyway, the fact that powering two network interfaces takes more than powering one stands.
