Hey guys, I am having a problem where suddenly my internet speed has slowed down a lot. I have a 25 mbps connection at home and usually, my internet speeds were pretty good although now all of a sudden when i try to watch a youtube video in 1080p or even in 720p, it starts buffering and downloads have slowed down a lot too. I have brighthouse and also using the modem that came with the service and am using the Cisco M20 router. The pc is running windows 8.1. Also there are about four (2 smartphones, 1 tablet, 1 iPod) devices using the wifi network. I also tried connecting the router to the modem directly via an ethernet cable and still no change. Can someone give me any advice?
