CBN Speed Test - Free Fiber Broadband Check

Run a free CBN speed test to accurately measure the performance of your Indonesian internet connection. This diagnostic tool checks your download speed, upload speed, latency (ping), and jitter in seconds. Once complete, you can compare your actual speeds against Cyberindo Aditama's officially advertised Fiber plans. If your results are lower than expected, read our guide to troubleshoot the red LOS light, understand CBN's CGNAT system, and bypass the factory Huawei router.

CBN Fiber Plans & Expected Speeds

Unlike many older ISPs in Indonesia that heavily throttle upload speeds, CBN is famous for providing symmetrical bandwidth (1:1 ratio). This means your upload speed should be nearly identical to your download speed.

Plan Name Advertised Download Speed Advertised Upload Speed Typical Monthly Price
Fiber 50 50 Mbps 50 Mbps Rp 299.000 / mo
Fiber 100 100 Mbps 100 Mbps Rp 399.000 / mo
Fiber 300 300 Mbps 300 Mbps Rp 599.000 / mo
Fiber 1G 1000 Mbps 1000 Mbps Rp 999.000 / mo

The Huawei & FiberHome Modem Breakdown

CBN typically provisions a Huawei or FiberHome Optical Network Terminal (ONT) for new installations. These act as both the fiber modem and the Wi-Fi router.

  • Admin Access: Navigate to http://192.168.1.1. For Huawei, the username is usually Account or admin, and the password matches the username (e.g., Account / Account). For FiberHome, try user / user1234. Always check the sticker on the back of the device.
  • The 94 Mbps Fast Ethernet Cap: If you are subscribed to Fiber 100 or Fiber 300, but your wired speed test is hard-capped at 94 Mbps, you are likely using an old Cat5 cable or a laptop with a Fast Ethernet port. You must use a Cat5e or Cat6 Gigabit Ethernet cable to see speeds over 100 Mbps.

The Ultimate CBN Troubleshooting Guide (Reddit Sourced)

To provide actionable technical advice, we've reviewed the most common complaints and workarounds discussed by Indonesian power users on r/indonesia.

1. The "No FUP" Reality Check

One of CBN's biggest selling points is that they do not enforce a Fair Usage Policy (FUP). Competitors often throttle your speed to 10 Mbps after you download a few hundred gigabytes. CBN power users confirm that they can download terabytes of data (e.g., massive Steam libraries) without facing sudden speed drops. However, users warn that running commercial servers on residential plans may still trigger an "abnormal usage" investigation.

2. CGNAT and the 10.xx IP Address Problem

Because public IPv4 addresses are exhausted, CBN places residential users behind Carrier Grade NAT (CGNAT). You can verify this by checking your router's WAN IP; if it starts with 10.x.x.x or 100.x.x.x, you are behind CGNAT.

  • The Problem: CGNAT causes "Strict NAT" types on PlayStation and Xbox, making it difficult to host multiplayer lobbies. It also breaks port forwarding for home CCTV servers.
  • The Solution: While there are rumors of users successfully requesting a dynamic Public IP from CBN support (1500780) by citing CCTV requirements, the official policy often restricts public IPs to business plans. The Reddit community strongly recommends using a VPN with port forwarding support (like Tailscale or ZeroTier) to bypass CGNAT restrictions entirely.

3. The Red LOS Light (Fiber Cut)

If the LOS light on your modem starts blinking red, you have suffered a physical "Loss of Signal". This is not a router glitch; it means the fiber optic cable outside your house is broken, bent, or disconnected at the pole. You cannot fix this via the router settings. You must call CBN Support at 1500780 to request a technician.

CBN Internet - Pros and Cons

Pros:

  • Truly unlimited data with no Fair Usage Policy (FUP) throttling.
  • Symmetrical 1:1 upload and download speeds, perfect for streamers.
  • Customer service (CS) is generally rated higher than state-owned competitors.

Cons:

  • Coverage is somewhat limited outside of major metropolitan areas.
  • Strict CGNAT implementation frustrates advanced users needing port forwarding.
  • Connection stability is highly dependent on the local neighborhood infrastructure ("gacha" routing).

Competitor Comparison

Competitor Network Focus Key Feature Differences
IndiHome (Telkomsel) Massive Nationwide Fiber The largest ISP in Indonesia. They have coverage almost everywhere, but they strictly enforce FUP limits and often have asymmetrical (slower upload) speeds compared to CBN.
Biznet High-Speed Pure Fiber A direct rival to CBN. Biznet also offers symmetrical speeds and no FUP, but users report their customer service can be harder to reach during mass outages.
First Media Coaxial / Fiber Hybrid Older infrastructure. They often bundle robust Cable TV packages but suffer from heavily asymmetrical speeds (very slow uploads) compared to CBN's pure fiber.

  • Global Ping Test - Check your latency from routing locations worldwide.

CBN Fiber - Frequently Asked Questions

Why is the LOS light red on my CBN modem?

A blinking red 'LOS' (Loss of Signal) light means your modem is not receiving an optical signal from CBN. This is usually caused by a broken fiber cable (fiber cut) or a loose connector. Ensure the yellow optical cable is plugged in tight. If it persists, call 1500780.

Does CBN throttle upload speeds?

No, unlike many other ISPs in Indonesia, CBN Fiber offers 1:1 symmetrical download and upload speeds on most plans. If you are getting 50 Mbps download, you should also get close to 50 Mbps upload.

How do I log into my CBN Fiber modem?

Connect to your WiFi, open a browser, and type http://192.168.1.1. The default username is commonly 'Account' or 'admin', and the password matches the username (e.g., 'Account' / 'Account'). Check the sticker on the back of your Huawei or FiberHome device.

How do I contact CBN Customer Service?

You can contact CBN 24-hour support by calling 1500780 from any phone, or email [email protected]. They can remotely diagnose your modem signal levels.

Why is my CBN WiFi slow but LAN is fast?

This is common. The factory-provided modem often has weak WiFi antennas. For best performance, disable the modem's WiFi and connect a dedicated high-performance Wireless Router (e.g., ASUS, TP-Link) to LAN Port 1.

What is the FUP for CBN Fiber?

CBN advertises 'Unlimited' internet without a Fair Usage Policy (FUP) cap on speed, unlike some competitors (e.g., IndiHome). You can download as much as you want without speed throttling.

How do I pay my CBN bill?

You can pay via BCA Virtual Account, Credit Card, or a variety of e-wallets (GoPay, OVO). Check your bill amount in the 'CBN Mail' sent to your registered email.
