Chapter 6: Troubleshooting

If the suggested solutions in this section do not resolve your issue, contact your system administrator or Internet service provider.

Problems with LAN

PCs on the LAN can not get IP addresses from the ADSL Router.

The chances are that the interface used as DHCP server is modified and the clients PCs do not renew IP addresses.

If your DHCP server is enabled on Private IP Address previously and you modify the interface to Public IP Address, the client PCs should renew IP addresses.

The PC on the LAN cannot access the Web page of the ADSL Router.

Check that your PC is on the same subnet with the ADSL Router.

The virtual server can’t be access after setting virtual server.

Check the filter rule of the port that virtual server service setting for example, the virtual server service set FTP 21 you need update the filter rule of the ftp 21 Direction setting: Choose filter the packets that incoming action (In Bound) are Allow on the interface.

Problems with WAN

You cannot access the Internet.

If your ADSL Router is set to routing mode and you use private IP addresses on the LAN, go to WAN Configuration > ATM PVC > Setup the ATM PVC Interface page. Make sure that Enable network address Translation (NAT) is checked.

Check the IP settings:

Go to LAN Configuration > IP Address page, ensure you specify IP address on Public IP Address field.

Or go to WAN Configuration > ATM PVC > Setup the ATM PVC Interface page, ensure you specify IP address on Specified Local WAN IP address field

Check the physical connection between the ADSL Router and the LAN.

If the DSL LED on the front panel is off or keeps blinking, there may be problem on the cable connecting to the ADSL Router.

At the DOS prompt, ping the IP address of the ADSL Router, e.g., ping 192.168.1.1. If the following response occurs:

Relay from 192.168.1.1 bytes=32 time=100ms TTL=253

Then the connection between the ADSL Router and the network is OK.

If you get a failed ping with the response of:

Request time out

Then the connection is fail. Check the cable between the ADSL Router and the network. Check the DNS setting of the ADSL Router.

At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if your DNS IP is 168.95.1.1, then ping 168.95.1.1. If the following response occurs:

Relay from 168.65.1.1 bytes=32 time=100ms TTL=253

Then the connection to the DNS is OK.

If you get a failed ping with the response of:

ADSL 500, ADSL 50 specifications

Siemens has made significant contributions to telecommunication technologies, particularly in the realm of Asymmetric Digital Subscriber Line (ADSL). Two prominent products in their portfolio are the Siemens ADSL 50 and ADSL 500, both designed to enhance broadband connectivity for residential and business users.

The Siemens ADSL 50 is a versatile modem that supports downlink speeds of up to 50 Mbps, making it ideal for users who require substantial data bandwidth for activities such as streaming, gaming, and video conferencing. One of its key features is the ability to optimize connection stability using advanced modulation techniques like DMT (Discrete Multi-Tone). This ensures efficient data transmission by dividing the bandwidth into multiple channels, allowing simultaneous data transfer without significant interference.

Another notable characteristic of the ADSL 50 is its built-in Quality of Service (QoS) functionality. This feature enables prioritization of traffic, ensuring that real-time applications like VoIP or online gaming experience minimal latency and jitter. The device is also equipped with multiple Ethernet ports, providing connectivity for various devices within the home or office.

Meanwhile, the Siemens ADSL 500 takes connectivity a step further by offering a higher maximum downlink speed of up to 500 Mbps. This model caters to users with more demanding bandwidth requirements, such as large enterprises or tech-savvy households with multiple users. Like the ADSL 50, the ADSL 500 employs advanced modulation techniques to manage data traffic effectively.

The ADSL 500 also features enhanced security protocols to safeguard user data, including WPA2 encryption for wireless connectivity, which is essential in today's digital landscape where cybersecurity threats are prevalent. Its compatibility with IPv6 ensures that it remains relevant as the industry transitions to this next-generation internet protocol.

Both models come with user-friendly configurations, typically allowing for quick set-up through web-based interfaces. They often include features like remote management and diagnostics, enabling users to troubleshoot connection issues efficiently.

In summary, the Siemens ADSL 50 and ADSL 500 provide robust solutions for broadband connectivity, combining high-speed capabilities with advanced features to meet the evolving needs of users. Their focus on stability, efficiency, and security makes them reliable choices for anyone looking to enhance their internet experience.
