If you prefer to disable ethernet periodically, keep your Ethernet cable plugged in. Just disable the adapter (right click disable). More resources saved that way as well.
I keep mine on.

Well I'm no hxx0rz kid but to me it seems that disabling the connection through so called "logical" connections (AKA software) would be more easily compromised than disabling the "physical" connection (no wire for anything to go through even if the system is somehow compromised).
Basically just trusting that the o/s actually DID cut the connection AND that a skilled individual wouldn't be able to override that command does not provide me with the same comfort that yanking the cord right out the back of the system (which actually takes LESS time than disabling the network card "logically").
And even if the system is compromised somehow if you only have the "physical" connection hooked up for short periods like I do it likely isn't enough time for any nefarious neer do wells to access the system to do anything useful to them like use it as a zombie, download data, upload data, etc.
It is an overabundance of caution but that's my DAW so I treat it like I would a guitar or an amp. I kind of liken leaving it connected to the tubes like leaving a piece of gear out on the sidewalk during load in. Get it in the club or back into the jam space ASAP and keep a VERY close eye on it while it sits there out in the open.
My laptop is where I do all my surfing and general internet nonsense because I can wipe/restore it very easily if something goes wacky.
