So in Devices in My Network I can monitor my devices connecting to it and a lot of strange and suspicous things are happening from all devices connected to my router being shown as online all at the same time even when some are powered off or just with Wi-Fi turned off.
The devices are two smartphones, one laptop where two devices are shown, I assume the second one with the same name is from the Wifi? Still turned off and was shown alongside all other devices as connected.
I’ve run a complete scan in Kaspersky aswell as Malwarebytes and it’s clean so it seems. I am concerned of a possible breach in my network. In my old router it already happened, my ISP recently installed a newer router and it still happens also I’m not fully sure how secure it is. What can I do to make sure I’m not compromised in any way?
