So every few days my WiFi will disconnect, and I will see the yellow triangle on my WiFi icon on the bottom right of my laptop screen. It happens to all devices connected to WiFi. It happens every few days. Once in a while, I get the asterisk symbol instead, but usually it is just the yellow triangle. I have a N300 router and fiber optic internet at 150 mbps down/25 mbps up. A simple unplugging of the router for about 10 seconds and plugging it back in fixes it no problem. My question is why does this happen, and how can I get it to stop altogether. Thank you.
