Your fiber link with a 150/150 plan from Frontier usually performs well, but noticeable spikes in latency can occur under heavy load. A ping time of 9–10 ms is typical, while 110–150 ms is more common during peak usage. This variation is normal depending on network conditions and traffic patterns.
Have you explored different IP addresses? It might just be the particular one in question. It doesn’t seem unusual for a network under stress to perform worse than one not under load, even though it’s noticeably slower. Consider running additional tests with other IPs.
Everyone seems confused about the topic. Increasing your connection speed will cause delays because your data is waiting in line and struggles to access the available network space.
How much strain are we putting on the system? If we fully utilize the connection, latency will increase as expected. The router is handling packet traffic as described earlier. I can usually sustain around 50% load while maintaining a ping of 8-9ms, but if the connection gets overwhelmed, the ping will rise as predicted. Are you running the Fios Quantum Router?
I’m checking how I’m affecting the network. Are you sending traffic from the same machine that’s making it slow? It might be a problem with the NIC on your device trying to handle the load. Try testing from another device on the LAN and observe if your latency improves.
