PLDT Speed Test
This diagnostic utility validates the real-time throughput of your PLDT Home Fibr connection. PLDT utilizes a Fiber-to-the-Home (FTTH) infrastructure, which typically delivers the most consistent latency and highest bandwidth in the Philippines compared to LTE/5G alternatives.
Understanding Your Speed Metrics
When evaluating your connection quality, focus on these three performance vectors:
Download Throughput: On Fibr plans (e.g., Plan 1699, 2099, or 2699), speeds should be consistent. However, PLDT often applies permanent "Speedboosts" to accounts. It is common to see 400 Mbps on a 200 Mbps plan. This is a feature, not an error.
Upload Throughput: PLDT Home Fibr plans are typically Symmetrical (Upload = Download). If you have 200 Mbps download, you should have ~200 Mbps upload. If your upload is significantly slower, you may be affected by a line profile misalignment.
Latency (Ping): PLDT generally offers the lowest ping to local servers (Manila/HK/SG) for gaming (Valorant/Dota 2). Typical latency is 5-20ms. If ping spikes, it is often due to CGNAT (Carrier Grade NAT) routing issues during peak hours.
What Results Should You Expect?
The "LAN Port 1" Rule
A specific quirk of PLDT modems (ONUs) is port configuration. Benchmarks include:
Download Speed: ~90-110% of plan speed (PLDT over-provisions slightly).
LAN Ports: For many users, Only LAN Port 1 is active for internet data. LAN 2 and 3 are often reserved for Cignal TV. If you plug a mesh node into LAN 2, it may not work or will limit speed to 10 Mbps.
Wi-Fi 5GHz: You must connect to the "5G" SSID to get speeds above 50 Mbps. The 2.4GHz band is too congested in Filipino subdivisions.
If you pay for 600 Mbps but your speed test caps at exactly 100 Mbps, check your Ethernet cable. You are likely using a "Cat5" cable or a router with Fast Ethernet ports, which cannot handle Gigabit speeds.
Why Is Your PLDT Connection Slow?
Before dialing 171, investigate these common premise-level faults:
LOS (Blinking Red): The "LOS" light is the most critical indicator. If it is blinking red, your physical fiber cable is broken or disconnected outside. No amount of restarting will fix this; you need a repair crew.
Modem Overheating: The white PLDT ONU (Huawei/FiberHome) generates significant heat. If it is placed flat on a cloth or in a hot room, it will throttle speeds to protect itself. Stand it vertically.
RPAD (Restricted): If you miss a payment, PLDT may put you in a "Walled Garden" or throttle your speed significantly until the bill is settled.
PLDT Technical Configuration Data
| Parameter | Configuration Details |

| Gateway IP | 192.168.1.1 |
| Admin Username | admin (Password often 1234 or on sticker) |
| Status Lights | PON (Steady Green = Good) / LOS (Red = Cut Line) |
| Support Number | 171 (PLDT Landline) / *171 (Smart) |
How to Get an Accurate Test
Wireless testing is unreliable due to the concrete walls common in Philippine homes.
To validate the actual bandwidth supplied by PLDT, connect a Cat6 LAN cable directly from LAN Port 1 of the modem to a laptop. This isolates the connection from Wi-Fi interference. If this wired test shows full speed, your line is healthy.
When to Call Support
Escalate the issue to PLDT support if you observe these specific failures:
Blinking Red LOS: Confirmed fiber cut.
Steady PON, No Internet: The modem has a signal, but the PLDT server is not assigning an IP address.
No Dial Tone: If your landline phone is dead, your internet will likely fail soon too.
You can report outages and get ticket updates via the myPLDT Smart App or by dialing 171.
