Frontier Fiber Speed Test

Frontier has been through a lot of changes over the years. They picked up a huge chunk of Verizon's Fios territory back in 2016, went through bankruptcy, and came out the other side with a completely different strategy: aggressive fibre expansion. If you are a Frontier customer today, there is a good chance your connection is on their upgraded XGS-PON fibre network, which delivers some genuinely impressive symmetrical speeds.

This speed test will show you what your Frontier connection is actually doing. Whether you are on the Fiber 500 plan, the 1 Gig, or one of the newer multi-gig tiers, the numbers should be pretty close to what you are paying for — assuming your hardware is not the bottleneck.

Frontier Fiber Plans — What You Should See

The key thing about Frontier Fiber: all plans are symmetrical. Your upload speed should match your download. If your test shows 500 Mbps download but only 40 Mbps upload, something is wrong — either a bad Ethernet cable, a misconfigured router, or an ONT issue.

Also worth noting: if you are still on Frontier DSL (legacy copper lines), symmetrical speeds do not apply. DSL plans might give you 25 Mbps download with only 2-3 Mbps upload. Frontier is actively upgrading these areas to fibre, but it has not reached everywhere yet.

Understanding Your Speed Test Numbers

Download speed should land within 5-10% of your plan speed on a wired connection. If you are on the 1 Gig plan and seeing around 940 Mbps, that is perfect — the small difference is normal Ethernet overhead. If you are testing over WiFi and seeing 300-500 Mbps, that is also normal. WiFi is always significantly slower than wired.

Upload speed on Frontier Fiber should be nearly identical to your download speed. This is the whole point of fibre — symmetrical delivery. If your upload is dramatically lower than download, start by checking the Ethernet cable between the ONT and your router. A damaged or loose cable is the most common culprit.

Ping (latency) on Frontier Fiber typically sits between 5 and 15 ms, depending on how close the test server is. Under 20 ms is great for gaming and video calls. If you are seeing spikes above 50 ms, there might be a routing issue or your router could be overloaded with too many simultaneous connections.

Router Login and Management

Frontier sends out different hardware depending on your plan and location. Here is how to access settings on each:

If you have an Eero, there is no web browser login — everything goes through the Eero mobile app. This frustrates some people who prefer a traditional router interface, but it does make the setup process very simple for most users.

Status Lights — What They Mean

Eero Router

Solid White: Online and working. You are good.

Blinking White: Booting up or connecting. Give it 3-5 minutes.

Solid Blue: In setup mode, waiting to pair with the Eero app. This should not happen after the initial setup.

Solid Red: No internet connection. This is the one that scares people. Check the ONT first — then check the Ethernet cable between the ONT and the Eero.

Arris NVG468MQ Gateway

Globe / Internet (Solid Green): Connected to Frontier and working.

Globe (Solid Red): Authentication failure. The gateway cannot talk to Frontier's network. Could be an outage or an account issue.

Globe (Off): No signal at all. Check your fibre or DSL connection to the wall.

ONT (Optical Network Terminal — the wall box)

Data / Optical (Solid Green): Fibre signal is active and healthy.

Data / Optical (Off or Red): The fibre signal is lost. This usually means a cut fibre line or an area outage. You cannot fix this yourself — Frontier needs to send a technician.

Common Problems and Fixes

Speeds capped at exactly 940 Mbps on a multi-gig plan

This is not an outage — it is a hardware limit. Your computer's Ethernet port is almost certainly a standard 1 Gigabit port, which maxes out at approximately 940 Mbps. To see the full speed of a 2 Gig or 5 Gig plan, you need a 2.5GbE USB-C adapter (~$20-30) or a 10GbE PCIe card, plus Cat6 or Cat6a cables. Make sure you connect to the correct port on your Eero — the 2.5G port on the Pro 6E or the 10G port on the Max 7.

Eero red light after a power outage

The trick with Frontier is that the ONT and the router need to come back up in the right order. If there is a power outage, the Eero might try to connect before the ONT is ready, and then just sit there with a red light. The fix: unplug both. Plug in the ONT first, wait for the green Data light (2-3 minutes), then plug in the Eero. Give it another 3-5 minutes.

DSL speeds dropping during rain

If you are on legacy Frontier DSL (not fibre), rain can cause water to seep into the copper connections at the pedestal or the NID box on the side of your house. This is a well-known issue with old copper plant. If speeds consistently drop during wet weather, report it to Frontier — they may need to repair or replace the outdoor connections. Or better yet, check if your address is eligible for a fibre upgrade.

Using your own router instead of Eero

Frontier Fiber uses a separate ONT, which means you can bypass the included Eero entirely. Just plug your own router's WAN port into the ONT's Ethernet port, set the WAN type to DHCP, and you are online. There is no PPPoE, no VLAN tagging, and no special authentication needed on Frontier Fiber. Popular alternatives include the Ubiquiti UniFi Dream Machine, Asus RT-AX86U, and TP-Link Archer AX80.

Wired vs WiFi Testing

Frontier's fibre speeds are high enough that WiFi becomes the obvious limitation. Here is the honest reality:

• Fiber 500: Most WiFi 6 devices can actually deliver close to 500 Mbps wirelessly when near the router. This plan is the sweet spot where WiFi and wired results are closest.
• Fiber 1 Gig: WiFi will typically show 400-700 Mbps depending on your device and distance from the Eero. A wired test should show ~940 Mbps.
• Fiber 2 Gig: You need a 2.5GbE port and Cat6 cable to test this properly. WiFi 6E gets you closer to 1+ Gbps, but wired is the only way to see the full speed.
• Fiber 5 Gig: 10GbE equipment required. WiFi cannot touch this speed. The value is in aggregate bandwidth across many devices.

When to Call Frontier Support

Call 800-921-8101 if any of the following apply:

• Your Eero light is solid red even after rebooting both the ONT and router in the correct order
• The ONT's Data/Optical light is off or red (this means the physical fibre line has a problem)
• Your Arris gateway's Globe light stays red persistently
• Wired speeds are consistently well below your plan speed
• You are on DSL and experiencing frequent disconnections during rain
• You want to check if your address is eligible for a fibre upgrade

Frontier Speed Test FAQs

Why is my Eero light solid red? Your Eero cannot reach the internet. Check that the ONT is powered on and its green Data light is solid. Then check the Ethernet cable between the ONT and the Eero. If both look fine, power cycle in the correct order: ONT first, wait for green, then Eero.

Is Frontier the same as Verizon Fios? Frontier acquired several former Fios territories from Verizon in 2016 (Florida, California, Texas, and others). The underlying fibre infrastructure is the same, but Frontier has since upgraded many areas to XGS-PON and rebranded as Frontier Fiber with different plans and pricing.

Can I use my own router with Frontier? Yes. The ONT is a separate device, so you can plug any router into it. Set WAN to DHCP — no PPPoE or special configuration needed. For multi-gig plans, make sure your router has a 2.5GbE or 10GbE WAN port.

Why am I only getting 940 Mbps on the 2 Gig plan? Your computer's Ethernet port is capped at 1 Gigabit. You need a 2.5GbE adapter and Cat6 cable to see speed above 1 Gbps. Connect to the 2.5G port on the Eero Pro 6E.

Does Frontier have data caps? No. All Frontier Fiber plans are unlimited — no data caps, no overage fees, and no throttling.

Is Frontier Fiber better than cable? Yes, for most people. Fibre provides symmetrical speeds (equal upload and download), lower latency, and no shared bandwidth with neighbours. Cable providers like Spectrum and Xfinity typically offer 20-35 Mbps upload on plans advertised at 300+ Mbps download.
