Speed Test Optus: Free NBN & 5G Connection Check

Welcome to our free, independent speed test optus diagnostic tool. Whether you are connected to Optus NBN, Optus 5G Home Internet, or utilizing their mobile network, this page provides an instant, accurate measurement of your download speed, upload speed, latency (ping), and jitter. It runs directly in your browser without requiring any third-party app installations.

How to Run an Accurate Optus Speed Test

  1. Pause network usage: Close background downloads, updates, HD streaming, and gaming on all devices sharing your connection.
  2. Use a wired connection: For the most precise measurement of your raw internet line, connect your PC directly to the Optus modem using an Ethernet cable.
  3. Stand near the modem: If testing over Wi-Fi, ensure you are in the same room as the Optus Ultra WiFi Modem to reduce local signal loss.
  4. Begin the test: Scroll up to the test panel and click Start to initiate the live bandwidth analysis.

Optus is Australia's second-largest telecommunications retailer. Their customers pay premium rates for broadband access. Running a regular optus speed test ensures your physical connection is performing normally and that you are receiving the typical speeds guaranteed under your NBN or 5G home internet subscription.

Why Perform a Speed Test on Your Optus Service?

A speed test is the primary tool for diagnosing slow internet connections. It measures download speed (crucial for streaming video and opening webpages), upload speed (necessary for uploading files, video calling, and gaming streams), and ping (crucial for real-time responsiveness). A regular optus internet speed test helps isolate whether slow speeds are caused by an Optus regional outage or are related to your home Wi-Fi environment.

The Ultra WiFi Modem Blue Light: Why is My Speed capped at 25 Mbps?

A common complaint from Optus customers is running a speed test and seeing download speeds capped at exactly **25 Mbps download and 2 Mbps upload**, even when subscribed to a high-speed NBN 100 or NBN 250 plan.

To diagnose this, inspect the **Internet** LED light on the front panel of your **Optus Ultra WiFi Modem Gen 2**: Indicators represent different network configurations:

  • Solid Green: Your primary NBN line is active and working normally. Your speed test results will represent your full plan speeds.
  • Solid Blue: Your primary NBN connection has dropped. The modem has automatically failed over to **Optus's 4G mobile backup network**. While this keeps you connected, the 4G backup has a strict speed cap of **25/2 Mbps**.
  • Solid Red: The modem has no connection. Both your primary NBN line and the backup 4G mobile network are offline.
  • Flashing Orange: The modem is starting up or downloading a critical system firmware update. Keep the modem powered on.

If your modem has a blue light, check the **My Optus App** for regional NBN outages. If no outage is listed and the blue light has persisted for more than 24 hours, perform a modem restart or contact Optus technical support (133 937).

Managing Your Ultra WiFi Modem (192.168.0.1 Login)

Optus supplies the **Sagemcom Ultra WiFi Modem Gen 2** (F@st 5366 TN) for fixed-line connections. It supports Wi-Fi 6 (802.11ax) and coordinates with Optus WiFi Boosters. Accessing settings:

Modem Configuration Sagemcom Ultra WiFi Modem Gen 2
Admin IP Address http://192.168.0.1
Default Credentials Username: admin / Password: [printed on sticker on the back/base of modem]
Wi-Fi Channel Tuning Navigate to Wireless > Advanced Settings > Channel Selection.
Optimal Wi-Fi Bands Change the 5 GHz band channel width to 80 MHz and set the channel manually to 36, 40, or 44.

In high-density apartment blocks, neighborhood routers often interfere with one another. Manually setting your 5 GHz Wi-Fi channels inside the admin page at `192.168.0.1` can improve stability and prevent unexpected dropouts during wireless speed tests.

Optus Game Path: How it Optimizes Ping and Latency

A unique feature offered by Optus is **Game Path**, a gaming routing optimizer. While it does not increase download or upload bandwidth, it actively improves latency (ping) and packet loss for gamers:

Normally, data packets take default routing paths across the web, which can be congested or indirect. Game Path acts as a custom routing network at the ISP level, choosing the most direct route with the lowest number of network hops between your device and major gaming servers. In domestic testing, Game Path reduces ping by up to 10%, while international routing to Southeast Asian servers (e.g. Singapore, Tokyo, Hong Kong) can see latency drops of 10-30 ms.

What Speeds Should You Expect on Optus NBN?

Optus offers multiple NBN speed tiers. Under ACCC regulations, ISPs must disclose realistic **Typical Evening Speeds** (measured between 7 PM and 11 PM) when network congestion is highest. Your **optus nbn speed test** should deliver the following range:

Optus Plan Speed Tier ACCC Typical Evening Speed Expected Wi-Fi Speeds Best Suited For
Home Standard (NBN 25) 25 Mbps download / 4 Mbps upload ~20 - 24 Mbps download Basic browsing, HD streaming, 1-2 users
Home Standard Plus (NBN 50) 50 Mbps download / 17 Mbps upload ~42 - 48 Mbps download 4K streaming, home offices, 2-3 users
Home Fast (NBN 100/20) 97-100 Mbps download / 17 Mbps upload ~80 - 95 Mbps download High-speed downloading, multiple users, gaming
Home Fast + Upload (NBN 100/40) 100 Mbps download / 34 Mbps upload ~80 - 95 Mbps download Heavy cloud uploads, content creation, home business
Home Superfast (NBN 250) ~230 Mbps download / 22 Mbps upload ~150 - 210 Mbps download Rapid updates, large families, power users
Home Ultrafast (NBN 1000) ~750 - 800 Mbps download / 42 Mbps upload ~350 - 550 Mbps download Fibre-to-the-Premises (FTTP) power users

Optus 5G Home Internet: Speed Test Expectations

In addition to physical fixed-line NBN, Optus offers 5G Home Internet. Since it connects wirelessly to local mobile towers using a Nokia FastMile modem, speed test results can fluctuate based on weather, user density, and tower load. Average download speeds range between 100 Mbps and 300 Mbps, with pings hovering between 15-30 ms. While it offers a great alternative to slow FTTN NBN copper connections, it is subject to peak-hour congestion fluctuations.

How to Troubleshoot and Optimize Optus Speed Results

If your optus speed test results are lower than expected, follow these systematic steps to isolate the issue:

  1. Power cycle your hardware: Turn off the Optus Ultra WiFi Modem, wait 60 seconds, and turn it back on. This resets internal caches and searches for cleaner Wi-Fi channels.
  2. Verify your connection type: Enter your address on nbnco.com.au. FTTN lines have sync speed limits due to copper distance. If your sync speed is capped, upgrading your plan will not yield faster speed tests.
  3. Isolate Wi-Fi bands: Ensure high-speed devices are connected to the 5 GHz Wi-Fi frequency rather than the slower 2.4 GHz band.
  4. Check the NBN connection box: If on HFC or FTTP, power cycle the NBN Connection Box (NTD) as well as your Optus router.

How Optus Compares to Other Australian Providers

  • Telstra: Telstra is Optus's primary competitor. Telstra plans are $10-15 per month more expensive, but they offer highly consistent typical evening speeds and mesh network upgrades.
  • Aussie Broadband: Aussie Broadband is a premium customer service provider offering transparent network logs and local support. Optus is generally cheaper and includes a built-in 4G backup.
  • TPG: TPG is a budget-oriented competitor. TPG plans are cheaper but lack built-in 4G failover backup modems.

In summary, Optus represents a solid middle ground: offering high-end features like Wi-Fi 6 modems and automated 4G backup at a lower monthly price tier than Telstra. For gamers looking to improve latency, their Game Path feature adds valuable routing flexibility.
