Virgin Media Speed Test

This diagnostic utility validates the throughput of your Virgin Media broadband connection. Unlike most UK providers (BT, Sky, EE) that use the Openreach telephone network, Virgin Media primarily utilizes a proprietary DOCSIS 3.1 Coaxial Network. This technology allows for incredible download speeds (Gig1) but behaves differently regarding latency and signal stability compared to full fibre.

Understanding Your Speed Metrics

When analyzing your connection integrity, focus on these three performance vectors:

Download Throughput: Virgin is the speed king. On Gig1, you should reliably see ~1130 Mbps at the Hub. However, DOCSIS networks are shared bandwidth at the street cabinet level. In extremely dense areas, you may see "Utilization" slow-downs between 7 PM and 10 PM, though this is becoming rarer with DOCSIS 3.1 upgrades.

Upload Throughput: Virgin plans are highly Asymmetrical. Even on the Gig1 plan, upload speeds are typically capped around 50-100 Mbps (depending on your specific area's upgrade status). If you are a streamer or content creator, this upload limit is your primary bottleneck.

Latency (Ping) & Jitter: This is the sensitive spot. The older Hub 3 uses the Intel Puma 6 chipset, which has a hardware flaw causing "micro-stutters" or latency spikes in gaming. The newer Hub 4 and Hub 5 do not suffer from this issues.

What Results Should You Expect?

The "Hub 5" 2.5G Advantage

Your hardware dictates your maximum test result. Benchmarks include:

Hub 5 (Wi-Fi 6): The only hub with a 2.5 Gbps Ethernet Port. If you have a PC with a 2.5G card, you can pull the full ~1140 Mbps. On standard Gigabit ports, you will cap at ~940 Mbps.

Hub 4 (Gigabit): Capable of Gig1, but known to run hot. Wired speeds cap at ~940 Mbps.

Hub 3 (Wi-Fi 5): Great for streaming, poor for gaming. Wi-Fi speeds often cap around 400-500 Mbps.

If you pay for Gig1 but your speed test is stuck at exactly 100 Mbps, check your Ethernet cable. A damaged Cat5 cable (or a cheap "Fast Ethernet" adapter) is the culprit 99% of the time.

Why Is Your Virgin Connection Slow?

Before calling "The Team," verify these common premise-level faults:

Loose Coax Cable: The white cable screwing into the back of the Hub is critical. It must be "Wrench Tight" (finger tight + a small turn with a spanner). If it is loose, "RF Noise" leaks in, causing packet loss and slow speeds.

Power Levels: Log into the Hub (`192.168.0.1`) and check "Network Status." If your Downstream Power is outside the range of -6 to +10 dBmV, or your Pre-RS Errors are rising rapidly, you need a technician to re-balance the cabinet amplifier.

Modem Mode: The Virgin Hubs have average Wi-Fi. Many power users switch the Hub to "Modem Mode" (Light turns Magenta/Green) and use their own Mesh system (e.g., Eero/Orbi) for vastly superior speed.

How to Get an Accurate Test

The standard "Speedtest.net" isn't always enough. Virgin has a partnership with SamKnows.

To verify if the issue is the network or your Wi-Fi, run a SamKnows RealSpeed test. This separates the results into "Speed to Hub" (The speed Virgin is delivering) and "Speed to Device" (The speed your phone is getting). If "Speed to Hub" is green, the Virgin network is fine, and you need to fix your Wi-Fi setup.

When to Call Support

Escalate the issue to Virgin Media if you observe these specific failures:

Flashing Green Light: The Hub cannot lock onto the cable signal (Upstream/Downstream failure).

Flashing Red Light: Overheating. Ensure the Hub is standing upright and not covered by curtains/books.

Area Fault: Check the "Service Status" page. Virgin outages are usually neighborhood-wide due to amplifier failures.

You can run diagnostics, check service status, and book a technician via the Virgin Media Connect App or by calling 150.
