How to get the most out of your Internet connection 

A stable and fast internet connection is essential for many Windows users, whether for streaming, working from home, gaming or cloud services. However, the DSL connection does not always reach the booked speed and connection problems can disrupt everyday life. In addition to the general network technology, the correct configuration of Windows also contributes to optimal Internet use. 

With the right settings and optimizations, latencies can be reduced, the connection stabilized and bottlenecks avoided.  

Differences between DSL and fiber optics in practical use 

DSL and fiber optics are the two most commonly used broadband technologies in Germany. While fiber optics is considered the most modern solution, DSL remains the most common choice for many households.

But how do the two technologies differ in daily use for streaming, meetings and cloud use?  

Windows network settings for a faster DSL connection 

A poor Internet connection is not always due to the provider - often Windows settings have a negative impact on network performance. The DSL connection can be optimized with just a few adjustments: 

• Customize DNS serverBy default, many computers use the DNS servers specified by the provider. Faster alternatives such as Google DNS (8.8.8.8, 8.8.4.4) or Cloudflare (1.1.1.1) can shorten the loading times of websites. 

• Optimize QoS settingsIn Windows, a bandwidth reservation can be adjusted via the Group Policy Editor to give priority to applications with high requirements (e.g. streaming or online gaming). 

• IPv6 or IPv4?In some networks, deactivating IPv6 can help if compatibility problems occur. This can be tested in the adapter settings. 

• Limit background servicesWindows runs numerous processes in the background that consume bandwidth. The speed can be optimized by deactivating automatic updates or restricting cloud synchronization. 

Hardware optimization: Adjust router and network settings 

DSL performance is influenced by various factors, including software settings and the hardware used. The correct placement of the router improves the signal quality. Thick walls or electronic devices such as microwaves can weaken the signal, so the router should be as free as possible from sources of interference. An elevated position can also improve the range. 

The choice between Wi-Fi and cable affects the stability of the connection. While Wi-Fi is flexible, a wired connection via a LAN cable often offers higher speed and lower latency. Especially for streaming, online gaming or video conferencing, a direct connection to the router ensures more reliable data transmission. If Wi-Fi is used, switching to the 5 GHz band can ensure a more stable connection, as it is less susceptible to interference than the frequently used 2.4 GHz band. 

Software adjustments can further optimize the connection. The network adapter in Windows can be customized via the device settings by deactivating energy-saving options and installing the latest drivers. Regularly updating the router firmware reduces connection problems and supports new functions. These measures improve the network quality in the long term. 

Common DSL problems under Windows and their solutions 

• Slow connection despite good tariff speed: A speed test can revealwhether the actual bandwidth corresponds to the booked bandwidth. If not, restarting the router or changing the DNS server may help. 

• High latency times and packet lossQoS optimizations and the use of a wired network can improve stability. 

• Sudden disconnectionsIt can help here to deactivate automatic updates in Windows, as these take up a lot of bandwidth in the short term. The router firmware should also be kept up to date. 

• WLAN signal too weakIf the WLAN signal is too weak, WLAN repeaters or powerline adapters can help to extend the network. 

Optimal DSL for Windows users 

With the right Windows optimizations, a good network configuration and small adjustments to the hardware almost any connection can be noticeably improved. 

While fiber optic scores with high speeds and low latency, DSL remains indispensable, especially in places where fiber optic is not yet available. If you optimize your connection with the right settings, you can also with a DSL connection enjoy stable and fast Internet use. 

The performance of a DSL connection can be significantly increased with a combination of software and hardware optimizations. Users should regularly check whether their connection can be further improved with new technologies or better tariffs. In this way, DSL will remain a viable solution for many households in the coming years.
