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 -> Conclusion: If your equipment supports EEE/802.3az, ethernet comes close, if not ethernet is significantly worse.
- Idle wireless uses only a few mW
When maintaining AP connection it is not really idle.
It is most of the time. Look up DTIM. Or read the linked reports. Average power consumption is < 10mW. Regards, Stefan -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
