Quick overview:
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 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 everyday use for streaming, meetings and cloud use?
| DSL | Glass fiber | |
| Speed | Up to 250 Mbit/s with vectoring | Up to 1 Gbit/s and more |
| Stability | Fluctuates depending on the distance to the distribution box | Constant transmission rates, less susceptible to interference |
| Latency | Higher ping times, less suitable for gaming and remote work | Low latency, ideal for online gaming and video conferencing |
| Availability | Almost nationwide in Germany | Not yet available in many regions |
| Costs | Cheaper tariffs and hardware | Higher basic fees and acquisition costs |
Windows network settings for a faster DSL connection
A poor internet connection is not always down to the provider - often Windows settings can have a negative impact on network performance. The DSL connection can be optimized with just a few adjustments:
- Adjust DNS server: By default, many computers use the DNS server 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 settings: In 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 services: Windows runs numerous processes in the background that consume bandwidth. The speed can be optimized by deactivating automatic updates or limiting cloud synchronization.
Hardware optimization: Adjust router and network settings
DSL performance is influenced by various factors, including software settings and the hardware used. Correct placement of the router improves 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 disabling 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 show whether the actual bandwidth corresponds to the booked bandwidth. If not, restarting the router or changing the DNS server can help.
- High latency and packet loss: QoS optimizations and the use of a wired network can improve stability.
- Sudden disconnections: It can help 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.
- Wi-Fi signal too weak: If the Wi-Fi signal is too weak, Wi-Fi 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 where fiber optic is not yet available. If you optimize your connection with the right settings, you can also enjoy stable and fast Internet use with a DSL connection.
The performance of a DSL connection can be significantly improved 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. This way, DSL will remain a viable solution for many households in the coming years.
