What is the best option to do a restart/reboot remotely?
I have it connected to a bridged router, which connects on wifi with my main router.
After I reboot manually, when everything works ok, I can access it through ssh, but not through web interface (i don't know how).
PS: it is possible that my problem is the bridged router, maybe it hangs and the l3plus is without connection..
Get one of these, you can turn on/off power from your phone: https://www.amazon.com/gp/product/B0178IC5ZY/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
Only has enough power for two L3+'s, but it's still a cool product. I'm assuming though if you've only got one or two miners you're just running them from your home in which case you wouldn't need this in the first place.
