TPG Speed Test

This page helps TPG NBN customers understand their internet speed test results and determine whether the connection is performing within the normal range for TPG broadband services.

TPG is known for providing high-value NBN plans, often bundling service with TP-Link modems like the Archer VR1600v. Understanding the difference between your NBN plan speed and your physical line sync speed (especially on FTTN) is key.

How to interpret your TPG speed test result

A TPG speed test measures three core performance metrics:

Download speed – Should be close to your plan speed (e.g., ~48 Mbps for NBN 50). If testing in the evening (7-11 PM), speeds may dip slightly due to congestion.

Upload speed – NBN 50 plans cap at 20 Mbps. NBN 100 plans can be 20 or 40 Mbps. TPG uploads are generally consistent.

Latency (ping) – Typically 10–25ms. If higher than 50ms, check if other devices are downloading large files.

These values should be evaluated based on the type of connection (Ethernet vs. Wi-Fi) and the time of day.

TPG NBN: Expected Performance

Connection characteristics

Technology: Primarily FTTN/FTTB (Copper) and HFC. Performance on copper degrades with distance/wiring quality.

Modem: TP-Link Archer VR1600v or VX420-G2h (Wi-Fi 6). Reliable but basic consumer hardware.

Typical Evening Speed: TPG advertises ~50 Mbps for NBN 50 plans during peak hours.

Typical real-world performance

Download speed: ~47-50 Mbps (NBN 50), ~90-100 Mbps (NBN 100).

Upload speed: 17-19 Mbps.

Latency: 10–20ms.

If you are on an FTTN connection and your speed is consistently below 25 Mbps, you may have a "co-existence" profile or line fault. Check your modem sync speed.

Common Causes of Slow TPG Speeds

Slow speed test results on TPG are often related to internal wiring issues in FTTN homes or Wi-Fi range.

Frequent causes

Wi-Fi Interference: Using the 2.4 GHz band in an apartment block is notoriously slow. Switch to 5 GHz.

Internal Wiring: Extra telephone sockets in your house act as "bridge taps," reflecting signals and lowering speed.

Background Updates: Game consoles or Steam updates can saturate your connection without you realizing.

TPG Modem Login – Default IP, Username & Password

Access your TP-Link modem admin panel to check your DSL stats and maximize your connection.

TPG Modem Details Information
Login IP Address 192.168.1.1 – Default for TP-Link Archer series
Default Username admin
Default Password admin (older models) or see bottom sticker (newer models)

Steps to Login

  1. Connect to your TPG Wi-Fi
  2. Open a browser
  3. Enter 192.168.1.1
  4. Enter 'admin' and 'admin' (or sticker password)
  5. Go to "Basic" > "Network Map" to see status

Troubleshooting Gateway Lights

Solid Internet: Connected and authenticated.

Solid DSL: Physical line is synced. If Internet light is off but DSL is on, you have an authentication error.

Blinking DSL: Trying to find NBN signal. Check cables.

Red Internet: Authentication failed. Username/Password settings may be wrong.

Wired vs Wi-Fi Testing on TPG

Speed test results over Wi-Fi are often 30–50% lower than wired results.

For accurate verification of NBN speeds, always test with a Cat5e Ethernet cable connected to a yellow LAN port on typical TPG modems.

When to contact TPG support

You should consider contacting TPG support (13 14 23) if:

Your "DSL" light is blinking for more than 30 minutes.

Your speed test is consistently below 12 Mbps (below NBN minimum standards).

You experience frequent dropouts during rain.

TPG Speed Test FAQs

Does TPG have 4G backup? Only on select plans with specific modems. Most standard TPG plans stop working if the NBN goes down.

Why is my upload speed only 17 Mbps? On NBN 50 plans, the maximum theoretical upload is 20 Mbps. After overheads, ~17-18 Mbps is the perfect real-world maximum.

Is TPG good for 4K streaming? Yes. A 50 Mbps connection can easily handle 2-3 simultaneous 4K streams (requires ~15-25 Mbps each).
