CBN Speed Test

This utility validates the real-time throughput of your CBN Fiber connection to ensure it meets the bandwidth promised in your Service Level Agreement (SLA). CBN (Cyberindo Aditama) utilizes a pure Fiber-to-the-Home (FTTH) infrastructure, which typically delivers lower latency and higher stability than hybrid coaxial networks.

While CBN is famous for its "No FUP" (Fair Usage Policy) guarantee, we often see speed complaints that stem from users connecting to the slower 2.4GHz Wi-Fi band or using older routers that cannot handle the symmetrical upload speeds.

Understanding Your Speed Metrics

When running the diagnostic, focus on these three critical performance vectors:

Download Throughput: The rate of data ingress. On CBN Fiber plans (e.g., Fiber 50, 100, or 1Gbps), this should remain consistent throughout the day as there is no "Peak Hour" throttling policy.

Upload Throughput: This is CBN's primary technical advantage. Unlike many competitors, CBN offers Symmetrical Speeds (1:1). If you pay for 100 Mbps download, you should also get ~100 Mbps upload. If your upload is significantly lower, it indicates a configuration error.

Latency (Ping): To local Indonesian servers (Jakarta/IX), ping should be <10ms. High latency often points to background saturation or a routing issue at the local node.

What Results Should You Expect?

The "Wireless Overhead" Factor

Wi-Fi physics always introduce speed loss. When testing over a wireless connection, standard benchmarks are:

Download Speed: ~90% of plan capacity (Must use 5GHz band)

Upload Speed: ~90% of plan capacity (Symmetrical)

Stability: Zero packet loss. Fiber lines should not drop during rain or bad weather.

If you are on the Fiber 100 plan but your speed test caps at exactly 30-40 Mbps, you are almost certainly connected to the 2.4GHz Wi-Fi band, which is physically incapable of faster speeds.

Diagnosing Connectivity Drops

Before contacting the Call Center, verify these common premise-level faults:

Band Steering: Many CBN routers combine 2.4GHz and 5GHz into one SSID. Devices often get "stuck" on the slower 2.4GHz frequency. Splitting the bands in the router settings often fixes speed issues instantly.

LOS (Loss of Signal): Check the Optical Network Terminal (ONT). If the "LOS" light is Blinking RED, the physical fiber optic cable entering your home is broken or cut.

Cable Category: Ensure the LAN cable connecting your router to your PC is Cat5e or Cat6. An old Cat5 cable will cap your Gigabit connection at just 100 Mbps.

CBN Technical Configuration Data

How to Get an Accurate Test

Wireless signals degrade through concrete walls and glass, making Wi-Fi unreliable for SLA verification.

To confirm the actual speed reaching your modem, connect a Cat6 LAN cable directly from the CBN ONT (Port LAN 1) to a laptop. This isolates the ISP connection from local Wi-Fi interference. If the wired speed matches your plan, the issue is your router placement, not CBN.

When to Call Support

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

Red LOS Light: A blinking red light means a physical line break.

Asymmetrical Speed: If your upload speed is consistently less than 50% of your download speed (indicating a provisioning error).

Total Blackout: The "PON" light is off, and you have no internet connectivity.
