TPG Speed Test

This diagnostic utility validates the throughput of your TPG Telecom connection. It is critical to identify the physical infrastructure powering your home: TPG NBN (using the government network) or TPG FTTB (using TPG's private infrastructure in apartment basements). While FTTB offers exceptional speeds over short copper runs, NBN performance varies wildly based on the "Multi-Technology Mix" (FTTN/FTTC/HFC).

Understanding Your Speed Metrics

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

Download Throughput: On TPG FTTB plans, speeds are typically ~90 Mbps because the VDSL run from the basement to your apartment is short. On NBN plans (NBN 50, NBN 100), speeds align with the ACCC "Typical Evening Speed" guidelines. If you see a hard cap at 12 Mbps, your NBN port has likely been "policed" due to line instability.

Upload Throughput: TPG residential plans are Asymmetrical.
• NBN 50: ~20 Mbps Upload.
• FTTB: ~20-40 Mbps Upload (Variable based on internal building wiring).
If you need faster uploads, you must upgrade to the NBN "Superfast" or "Ultrafast" tiers, though upload is usually capped at 25-50 Mbps by NBN Co.

Latency (Ping): TPG is known for efficient routing (often better than budget TPG sub-brands like iiNet in some states). Expect 5-20ms to local servers. If latency spikes >100ms on FTTB, it is often due to crosstalk from other VDSL lines in the building's riser shaft.

What Results Should You Expect?

The "VLAN ID 2" Trap

Your configuration is the biggest variable. Benchmarks include:

NBN 100 (HFC/FTTP): ~95-100 Mbps Download.

FTTB (Private): ~85-95 Mbps Download. (Note: TPG FTTB is VDSL2 technology, so it degrades if your apartment is on the top floor of a 30-story building).

Sync Speed: Log into your modem. If your "Line Rate" (Sync) is 50 Mbps, but your speed test is 20 Mbps, you have a Wi-Fi bottleneck. If your Sync is 20 Mbps, you have a physical copper line fault.

If you have a third-party modem and the Internet Light is Red despite the DSL light being Green, you have almost certainly forgotten to enable 802.1Q VLAN Tagging (ID 2).

Why Is Your TPG Connection Slow?

Before calling support (13 14 23), verify these common faults:

Internal Wiring (FTTB): In older apartment blocks, the copper wire from the MDF (Basement) to your wall socket is often decades old. If you hear static on the landline phone, this corrosion is killing your internet speed.

Modem Hardware: The standard supplied modems (TP-Link VR1600v or VX420) are decent, but their Wi-Fi range is limited. If you are 2 rooms away, 5GHz will drop out, forcing you onto the slow 2.4GHz band.

Parallel Sockets: If you have multiple phone ports in your unit, ensure nothing else is plugged in. Unused sockets act as "Bridge Taps," reflecting the VDSL signal and causing errors.

How to Get an Accurate Test

Wireless testing is unreliable due to the high interference in apartment buildings (FTTB users).

To confirm the actual speed delivered to your premises, connect a Cat6 Ethernet cable directly from the TPG Modem (LAN Port) to a laptop. This isolates the connection. If this wired test is fast, the issue is Wi-Fi congestion from your neighbors.

When to Call Support

Escalate the issue to TPG support if you observe these specific failures:

No DSL/WAN Light: The modem cannot detect a signal from the wall. (Line Cut).

Auth Fail: If the System Log shows "PPPoE Authentication Failed," verify your password. TPG often suspends accounts for missed payments immediately.

Stability Profile: If your connection drops every time it rains, ask TPG to apply a "Stability Profile" (caps speed slightly to prevent dropouts).

You can check service status and run line tests via the TPG "My Account" portal or by calling 13 14 23.
