Warm Reboots vs Power Cycling
From my understanding it's bad for chips to change temps regularly... i.e. turning off a router at night, then turning it back on in the morning. The chips go from hot to cold, back to hot... and over time this prematurely wears them (from what I've read). This was the reason I chose the R7000 as I can turn wifi off with the physical button and leave the router up 24/7. (With maybe an occasional power cycle if needed.)
My question is, is it detrimental to longevity in the same way to do a warm reboot, once daily?
I ask because I'm running Advanced Tomato and toggle off wifi at night. In the morning iwhen I re-enable wifi, the button's LED stays off (unlike stock FW), I can set the wifi button for a longer press, that will instead reboot the router. This has the effect of turning wifi back on AND re-enabling the wifi button's LED, (which I want on because at night when it's dark and I want to toggle wifi off I want to see the button). So a 2-sec press toggles wifi off at night, and a 4-sec press in the morning reboots the router.
Is that bad for the router over the loing haul, to do a warm reboot each morning? TIA

Again, the question wasn't about turning wifi off (which I know is fine), or about a cold boot (which I am not doing).... it was about a daily warm boot.
Instead of providing so much info I should have just asked:
"Is a daily warm boot ok, or will it wear the router faster?"
:)
Since your wanting too do a warm boot the hardware should be ok , The firmware is should load correctly as long no issues pop up during the booting process is the main danger I can see. Your just reloading the os(firmware) like you would in a computer with a reset(reboot) button.

That's a pretty old notion. Not sure that it has ever been scientifically proved with domestic kit that does not use thermionic valves.
"Thermionic valves." I was just about to mention those!

It is also a "soldered joints" phenomenon.
Far fewer of those around these days.
