Forking this original message for a moment… Do you have any IoT devices? “Smart” devices? Are you an android user with many devices (such as phones and tablets)? Or similarly that with Apple devices? Do you have separate networks for your IoT devices and/or guests and/or mobile devices? Apple and Android OSes are known to sync and report, handshake and then chill out for a period of time - this is how they keep batteries from dying in an hour or two when in sleep mode. Same thing applies to apple laptops and I presume chrome books as well. — Ryan > On Feb 10, 2020, at 6:48 AM, o1bigtenor <o1bigtenor at gmail.com> wrote: > > > Now I am also seeing small spikes of incoming traffic about 3x every 2 > hours and I'd like to find out where that traffic is coming from and , > if I don't like who's doing the sending, to curtail it.
