Yes, you can often use your existing router with fiber optic internet, but there are crucial considerations. Understanding compatibility, potential limitations, and when an upgrade is necessary will ensure you get the most out of your high-speed connection. A gig fiber connection will provide around 1,000 Mbps download and 1,000 Mbps upload —but you won't always see those numbers if you run a speed check on your computer. That bandwidth is shared between all. I was expecting dl speeds of 900+ on wired connection and 600+ on wifi when close to router, what I am getting is 100 (dl) on wired and max of 350mb on wifi when sitting on top of the router, other rooms in my apartment are getting 50-200~ on the wifi network. Routers designed for DSL (which uses phone line inputs) or cable (which uses coaxial inputs) won't work. I worked with the Cybernews.
