This guide covers the Tenda 4G630 wireless N300 router, specifically for users with firmware version v1.0.0.29-en. This model is designed for 300Mbps wireless speeds and is highly versatile, supporting 3G/4G USB modems, standard wired internet, or acting as a wireless repeater. 1. Hardware Setup & Installation

Before configuring the software, ensure your hardware is connected based on your internet source:

3G/4G USB Modem Mode: Plug your activated 3G/4G USB modem into the router's USB port.

Wireless Router Mode: Connect an Ethernet cable from your internet-enabled modem (DSL/Fiber) to the WAN port of the router.

Power On: Plug the power adapter into an outlet and the router. The SYS light should blink, and the WiFi light should be on. 2. Accessing the Management Page 4g630-v1.0.0.29-en

To configure settings, you must log in to the web interface:

Connect to the Router: Connect your computer or smartphone to the router via an Ethernet cable or Wi-Fi (default SSID is usually "Tenda_XXXXXX").

Open Browser: In the address bar, type the default IP: 192.168.0.1 and press Enter.

Login: Use the default password admin. Some versions may not require a password for the initial login; if prompted, try leaving it blank first. 3. Setting Up Your Internet Mode Once logged in, choose the mode that fits your setup: This guide covers the Tenda 4G630 wireless N300

Changes and Improvements

Additional Updates in v1.0.0.29-en:

  1. Security Fix (Critical):

    • Resolved a potential vulnerability in the TR-069 protocol stack that could allow unauthorized remote management requests from the WAN side. The UPnP buffer handling has been hardened to prevent potential overflow exploits.
  2. Bug Fix:

    • Fixed an issue where the 4G signal icon on the Web GUI would incorrectly display "No Service" after the router recovered from a forced reboot (power loss), requiring a manual refresh. The status monitoring daemon now correctly re-polls the modem immediately upon initialization.
  3. System Stability:

    • Updated the 4G baseband driver to improve compatibility with specific regional carriers that utilize Band 20 (800MHz) aggregation, reducing the frequency of random disconnects during high-load traffic.

The string "4g630-v1.0.0.29-en" appears to be a version or firmware identifier, likely for a device or software component. Here’s a typical breakdown:

2. Typical Hardware Architecture Underpinning 4g630

Devices running this firmware are likely purpose-built for industrial or high-reliability applications. Based on similar product lines (e.g., Huawei ME909u-521 or Quectel EC25), the underlying hardware probably includes:

Such a device would run an embedded Linux distribution (possibly OpenWrt, Buildroot, or a vendor RTOS like ThreadX) with the v1.0.0.29 firmware image providing the kernel, drivers, network stack, and management UI.
