Yep but he just wants to reboot his router not his modem. Then again I also have Alexa setup to reboot my modem as well.
Then Alexa just reboots my main network and not my router. So everything connected to my router doesn’t disconnect. So pretty much Alexa will do either or.
Another option is do download the netgear nighthawk app and just hit the reboot router link but if your feeling lazy then use Amazon’s Alexa. I’m sure it’s possible to setup a routine in the Alexa app to reboot router daily, weekly, monthly, or every second if he chooses.
Hope this answers your question.
