Home / Will fiber optic cable connected to a router cause lag
Users pay high in exchange for high speed fiber internet, but many still face issues, including buffering, lag, and poor WiFi. Is your router plugged directly into the ONT? Or is there a ISP provided "modem"/router in between your router and the ONT? Are you DHCP, Static IP, PPPoE? Can you direct connect 1 computer to the ONT for a while and see if it continues? Or use the ISP supplied router for a bit? Ether can eliminate. Ethernet cables that are worn out, damaged or not properly connected can slow down or interrupt your connection. Fiber can improve the connection coming into your home, but it can't automatically fix what happens after that signal reaches your router, your Wi-Fi, or, ultimately, whichever devices you want to use. Understanding these potential points of failure is the first step in effective troubleshooting.
