Verizon Fios Speed Test
Verizon Fios is a 100% fiber-optic network available across much of the Northeast, with symmetric plans from 300 Mbps to 2 Gbps. Fios consistently ranks near the top of speed-consistency studies, so if your test comes back far below plan, the cause is usually inside your home network rather than Verizon's line.
What speeds should Verizon Fios deliver?
Fios plans deliver symmetric speeds — 300/300, 500/500, and Gigabit (typically 940/880 Mbps due to overhead) — and wired tests routinely hit those marks. The 2 Gig tier requires the newer WiFi 6E/7 router and multi-gig ethernet to measure fully.
If your download is fine but results feel inconsistent room to room, the router's location is the usual suspect. Fios routers often sit where the ONT was installed (basements, closets) — the worst possible WiFi position.
Slow Verizon Fios speeds? Try this first
- 1Test wired to the Fios router first; the Gigabit plan should show ~900 Mbps down and ~850+ up on a wired gigabit port.
- 2If your Fios router is in the basement near the ONT, move it centrally using the existing coax (MoCA) or ethernet run — placement alone can double whole-home WiFi speeds.
- 3Older Fios Quantum Gateway routers predate WiFi 6; renters on gigabit plans should ask Verizon for the current router model.
- 4Check the My Verizon app for outage alerts and router health before assuming a plan problem.
