It breaks the network of entire house – V380S Review

I live in a small townhome. My router is on 2nd floor and I put the bulb near my front door. The bulb should not be more than 5 meters away. My router is quite strong. My phone can connect to my router when I step outside but not far from front door. But I just can’t get the bulb working when put it near the front door. Even worse, my two laptops all dropped connection when I turn the bulb on. I have to turn off the bulb and reboot to get connection back.
