CBN Speed Test
This tool verifies Internet speeds for CBN (Cyberindo Aditama) subscribers across Indonesia. Whether you are on the entry-level Fiber 50 Mbps plan or the ultra-fast Fiber 1 Gbps package, this test confirms you are receiving the symmetrical bandwidth promised.
CBN is one of the distinct ISPs in Indonesia that offers a 1:1 upload-to-download ratio on most residential fiber plans, making it ideal for content creators, streamers, and work-from-home professionals.
Interpreting Your CBN Fiber Results
Download Speed:
- Fiber 50: Expect ~45-50 Mbps.
- Fiber 100: Expect ~90-100 Mbps.
- Fiber 1G: Requires a specialized 10G-capable router and Cat6 cables to measure
fully.
If your result on a high-speed plan is stuck at exactly 94 Mbps, check if your router or laptop only has a
Fast Ethernet (100 Mbps) port instead of Gigabit.
Upload Speed: Should be nearly identical to your download speed (Symmetrical). If download is 50 Mbps and upload is only 10 Mbps, contact support as there may be a configuration error on your line.
Ping (Latency): <5ms to local Jakarta servers. 15-30ms to Singapore. Low latency is critical for gaming.
CBN Modem Login (192.168.1.1)
To change your WiFi password ("Ganti Password WiFi") or check optical signal levels, you need to access the modem's admin page. CBN typically issues Huawei or FiberHome ONT devices.

Troubleshooting Slow CBN Speed Test Results
CBN Fiber is famous for symmetrical bandwidth, but local issues can impact your speeds. Use this troubleshooting checklist if your test results are lower than expected:
The Fast Ethernet 94 Mbps Cap
If you are subscribed to CBN's Fiber 100 Mbps or Fiber 1 Gbps plan and your speed tests are capped at exactly 90–94 Mbps, you are limited by a Fast Ethernet port. This happens if you use an older Cat5 cable (which only supports 100 Mbps) or if your computer's LAN card is set to 100 Mbps instead of 1 Gbps. Upgrade to a Cat5e or Cat6 Ethernet cable and ensure a Gigabit Ethernet interface is active.
- Verify Red LOS Light: A blinking red LOS (Loss of Signal) light means your modem is not receiving an optical connection from CBN. Avoid kinking the yellow fiber optic patch cable on the back of your Huawei or FiberHome ONT. If it stays red after checking the connector and rebooting, call 1500780.
- Run Tests Over a 5 GHz Wireless Connection: Standard 2.4 GHz bands are highly congested in residential areas (Jakarta/Surabaya), limiting real speed tests to 30-40 Mbps. Switch to the 5 GHz band on your router or connect via an Ethernet cable.
- Check Authentication (Internet Light Off): If your PON light is solid green but the Internet light remains off, your modem is receiving an optical connection but failing to log in. This typically points to server maintenance or bill status.
- Isolate Client Overhead: Slow downloads can be caused by background updates, antivirus programs, or multiple active devices streaming concurrently on the network. Pause other devices before starting the speed test.
When to Contact CBN Support (1500780)
Call the 24-hour hotline at 1500780 or email customercare@cbn.net.id if:
- The modem LOS light continues blinking red after cable validation.
- Wired Ethernet speed test results are consistently below 50% of your plan's speed.
- You need custom router configurations, static IP allocations, or port forwarding setups.
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 customercare@cbn.net.id. 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.
