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.

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.

Modem Brand	Login Details
Huawei (Common)	http://192.168.1.1 User: Account / Pass: Account or User: admin / Pass: admin
FiberHome	http://192.168.1.1 User: user / Pass: user1234

Troubleshooting Connection Issues

Red "LOS" Light: This is the most common fiber issue. It means "Loss of Signal".
1. Check the yellow fiber patch cord. It is fragile; do not bend it sharply.
2. Ensure the connector is clicked firmly into the modem's "PON" or "Optical" port.
3. Reboot the modem. If the light stays red, the main cable line outside is likely broken.

Internet Light Off: If the PON light is Green but the Internet light is off, your modem is receiving a signal but fails to authenticate. This could be due to an unpaid bill or a server-side maintenance issue.

When to Contact CBN Support (1500780)

You should contact CBN support immediately if:

You see a blinking Red LOS light that does not go away after checking cables.

Your speed is consistently below 50% of your package advertised speed.

You need to request a static IP or open ports for CCTV/Gaming.

CBN Speed Test FAQs

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