Q7. My PC cannot access the Internet.

A7: Use the ping utility, described on page 174 of the UG, check whether your PC can communicate with the ADSL2+ Modem Router 's LAN IP address (by default 192.168.1.254). If it cannot, check the Ethernet cabling.

If you statically assigned a private IP address to the computer, (not a registered public address), verify the following:

1.Check that the gateway IP address on the computer is your public IP address. If it is not, correct the address or configure the PC to receive IP information automatically.

2.Verify with your ISP that the DNS server specified for the PC is valid. Correct the address or configure the PC to receive this information automatically.

3.Verify that a Network Address Translation rule has been defined on the ADSL2+ Ethernet Router to translate the private address to your public IP address. The assigned IP address must be within the range specified in the NAT rules (see User Guide, Chapter 4). Or, configure the PC to accept an address assigned by another device (see “Quick Start Part 2 Configuring Your Computers”). The default configuration includes a NAT rule for all dynamically assigned addresses within a predefined pool (see the instructions in Chapter 8 to view the address pool).

Q8: I forgot/lost my Web Configuration user ID or password.

A8: If you have not changed the password from the default, try using “admin” as both the user ID and password. Otherwise, you can reset the device to the default configuration by pressing the Reset button on the back panel of the device three times (using a pointed object such as a pen tip). Then, type the default User ID and password shown above. WARNING: Resetting the device removes any custom settings and returns all settings to their default values.

Q9. My changes to Web Configuration are not being retained.

A9. Be sure to use the Commit function after any changes. This function is described on page 47 of the User Guide.

One of the standout features of the TDM-E400 is its capability to transmit Ethernet signals over existing coaxial cable, which can significantly reduce installation costs and time. This allows for seamless integration into environments where coaxial cabling is already in place, such as older buildings or setups where running new cables is not feasible. The TDM-E400 supports long-distance Ethernet transmissions, extending connections up to 4,000 feet (1,220 meters) over coaxial cable.

This device operates using advanced technology that ensures high-speed data transmission. It supports both 10/100 Mbps Ethernet connections, accommodating standard networking needs. The TDM-E400 includes features like auto-sensing and automatic MDI/MDI-X crossover, allowing for easy plug-and-play setup without requiring manual configuration.

Another notable characteristic of the TRENDnet TDM-E400 is its versatility in terms of powering options. It supports Power over Ethernet (PoE), which simplifies installation by allowing the device to receive power through the Ethernet cable, eliminating the need for additional power adapters and outlets. This feature is particularly beneficial in environments where power sources may be limited or where the device needs to be mounted in a hard-to-reach area.

In terms of build quality, the TDM-E400 features a compact and rugged design, ensuring durability in various operating conditions. Its intuitive LED indicators provide real-time status updates, making it easy to monitor network status and troubleshoot potential issues.

Additionally, the TDM-E400 is designed to work seamlessly with a range of networking devices, making it an ideal choice for integrating wireless access points, industrial devices, or IP cameras into existing coaxial networks. With its combination of extensive range, ease of use, and robust performance, the TRENDnet TDM-E400 stands out as a reliable solution for businesses and organizations looking to expand their network capabilities with minimal disruption.
