What is the China Unicom router login IP?

The default gateway for China Unicom Fiber modems (Optical Cats) is typically 192.168.1.1 (or sometimes http://192.168.1.1/cu.html).

What is the default admin password for China Unicom?

The standard user is 'user' with a random password printed on the sticker. The Super Admin username is often 'CUAdmin' but the password changes dynamically or is 'CUAdmin' on older models.

Why is the LOS light flashing red?

A flashing red LOS light means the fiber optic signal is interrupted (Loss of Signal). This usually requires a technician to repair the line.

Why is my internet slower than the plan I pay for?

Speed tests over 2.4GHz Wi-Fi are often much slower than fiber speeds. Always test with a 5GHz Wi-Fi connection or a wired Ethernet cable to see true speeds.

China Unicom Speed Test (中国联通测速)

This page helps subscribers of China Unicom (中国联通) verify their fiber broadband speed. Ensure your "King Card" (王卡) or Fiber Broadband plan is performing as promised.

China Unicom is traditionally dominant in Northern China but offers high-quality fiber nationwide. Typical plans are 300M, 500M, and 1000M (FTTR).

Understanding the Speed Test

A China Unicom speed test checks:

Download Speed: The most important number for streaming and downloading. A 500M plan should result in ~50-60 MB/s actual download rates (approx 500 Mbps).

Upload Speed: Affects video call quality and file sending. Often capped lower than download.

Latency (Ping): Key for gaming. Unicom often has good routing to Japan and Korea compared to other ISPs.

For accurate results, test using a wired Ethernet connection.

China Unicom Fiber: Performance

Network Details

Technology: FTTH (Fiber to the Home). Often advertised as "Gigabit Optical Network".

Gateways: Huawei, FiberHome, and ZX (ZTE) modems.

Stability: Excellent domestic peering, especially in Northern provinces.

Expected Speeds

Wired: 90-100% of plan speed.

Wi-Fi 5GHz: 300-700 Mbps depending on distance.

Wi-Fi 2.4GHz: 30-80 Mbps (Not recommended for speed testing).

Common Issues & Fixes

Slow Wi-Fi: Ensure you are connected to the 5G band. The 2.4G band is crowded in apartment complexes.

Speed Capped at 100M: Check your Ethernet cable. It must be Cat5e or Cat6 to support speeds above 100 Mbps. Cat5 cables are limited to 100 Mbps.

Light Indicators (Optical Modem)

Power: Green = Power OK.

PON: Green/Solid = Internet OK.

LOS: Red/Flash = Fiber Broken. Call 10010.

When to Contact Support (10010)

Dial 10010 if:

The LOS light is flashing red.

You cannot connect to the internet.

Your speed is significantly lower than your plan for several days.

FAQs

How do I fix the red LOS light? This indicates a physical problem with the fiber line. You cannot fix it via software. Check for loose cables, otherwise call Unicom support.

What is the difference between Unicom and Telecom? Historically, Unicom (Liantong) is stronger in the North, and Telecom (Dianxin) in the South. Now both are nationwide, but gaming servers may still favor one or the other.
