Quick Unboxing & Review of 5G CPE NRadio C2000MAX- Zeruns's Blog

A quick unboxing and review of the NRadio C2000 MAX 5G CPE.

I bought this 5G CPE to replace my broadband. The current broadband in my rented apartment is 300Mbps for 100 RMB/month, which is a bit pricey. I bought a ZTE F40 portable WiFi a few days ago, but its performance wasn't quite enough for me, so I purchased this one.

Unboxing

Front of the box

Bottom of the box, printed with device specifications and the network access license.

Opening the box, the first things you see are a user manual and a card indicating the built-in 5G high-speed data card.

User Manual

Removing the manual reveals the NRadio C2000MAX underneath.

Below that are the power adapter and power cable.

The power cable is a dual Type-C male to male, with one end being an L-shaped right-angle plug. The power adapter model is S9-PD20W-GAN, manufactured by Shenzhen Wanyou Electronic Technology Co., Ltd., and supervised by Shenzhen Jiahaoxin Electronics Co., Ltd. It has an input of 220VAC, and an output of 5V/3A, 9V/2.22A, 12V/1.67A. Judging from the model, it appears to be a GaN (Gallium Nitride) charger, supporting the PD protocol with a maximum output power of 20W.

Network Speed Test

Location: Inside a room in a tech park in Guangming District, Shenzhen

China Telecom 5G

Network information is shown below. Signal strength is -94dBm, band n78 (3.3GHz-3.8GHz). The signal is relatively weak, and neither 5G-A nor Carrier Aggregation was triggered (they appear occasionally, likely due to base station coverage issues in my area).

On the left is the C2000MAX, with a download speed of 346.24Mbps and upload of 65.4Mbps;

On the right is the Huawei Pura 70 Pro+, with a download speed of 283.31Mbps and upload of 30.75Mbps.

China Mobile 5G

Network information is shown below. Signal strength is -79dBm, band n41 (2.5GHz-2.7GHz). The signal here is quite good.

On the left is the C2000MAX, downloading at 357.84Mbps and uploading at 37.7Mbps;

On the right is the Huawei Mate 70 Pro+, downloading at 381.09Mbps and uploading at 37.42Mbps.

Max Wi-Fi Rate

The maximum negotiated Wi-Fi rate on the 5GHz band is consistently around 2401Mbps.

Power Consumption Test

When supplied with a 5V input, it cannot boot normally; the current fluctuates within 0.2A. The output capacity of this specific USB-A port is 5V/2A.

Switched to China Telecom 5G and connected one Wi-Fi device. When idling (not transmitting data), power consumption is around 4.6W.

Switched to China Telecom 5G and connected two Wi-Fi devices. While running a speed test, power consumption jumps to about 9.5W.

Data Plan Pricing

The version I bought has 1 built-in data card and can accommodate 2 extra SIM cards. The built-in card is provided by China Mobile.

For 1TB of data per month, the annual package is 599 RMB (about 49.9 RMB/month), and the monthly package is 79 RMB/month. The pricing is quite reasonable.

Admin Dashboard

The dashboard homepage displays basic device and network information.

The Cellular Status page shows detailed info of the current cellular network (Signal strength RSRP, Cell ID, Network mode, IP, DNS, Carrier, RSRQ, SINR, Frequency, Band, etc.).

The Cellular Settings page. Here you can switch SIM cards or set it to auto-switch (based on data usage) and set data thresholds.

The SIM Card Settings sub-page under Cellular Settings. You can manually select the network mode (5G or 4G), enable/disable carrier aggregation, and configure features like base station drop prevention, peak guarantee, and data roaming.

You can also set band locking and cell locking. The cell locking settings page allows you to scan and retrieve cell information.

Wi-Fi Settings page.

Terminal Settings page.

Advanced features in the More Settings page. You can enable UPnP, DMZ, etc., configure IPv6, and set port mapping and terminal device rate limiting.

After inserting a TF card, you can install apps like File Manager and NetEase UU Booster from the App Store located in the More Settings page.

System Firmware

The C2000MAX supports NROS/OpenWrt systems.

NROS is the factory default system, which is actually developed based on OpenWrt. Since the built-in Flash space is quite small, this system is likely a stripped-down version.

There is also an OpenWrt open-source firmware system available, which needs to be flashed onto a TF card and set up to boot from external storage. The firmware download link can be found in the official QQ group, but I have uploaded it to a cloud drive for direct download; the archive contains the flashing tutorial.
