Fiber Luxembourg: what internet speed do you really need?

min read / 1 October 2025

Today, everything happens online: video meetings, online gaming, 4K streaming and even smart homes. But what speed should you choose to avoid interruptions and maintain optimal comfort? With fibre in Luxembourg, the speeds on offer vary greatly… and are not always easy to compare. This article will help you understand your actual needs based on your usage (teleworking, gaming, streaming) and see why very high-speed Internet, such as Eltrona's 1 GiGA offer, covers all of these uses without compromise.

What internet speed is required for remote working?

Teleworking requires a stable connection capable of handling multiple uses simultaneously:

  • HD videoconferencing,
  • sharing large files,
  • cloud access and business software.

👉 Minimum requirement: 50 to 100 Mbps for a single person.

👉 For a multi-active household: 300 Mbps and above to avoid saturation.

With 1 GiGA fibre, you have a comfortable margin, even if three video conferences are taking place at the same time in the home.

What internet speed is required for online gaming?

Online video games do not necessarily consume a lot of bandwidth, but they do require:

  • low latency (< 30 ms),
  • a stable download speed for updates (sometimes >100 GB).

👉 Minimum requirement: 100 Mbps for uninterrupted gaming.

👉 For demanding gamers: 500 Mbps and above to combine online gaming, Twitch streaming, and fast downloads.

With Eltrona’s ultra-fast broadband internet, gigabit speeds not only guarantee low latency but also the ability to play games while watching a 4K stream.

What internet speed is required for video streaming?

Streaming is one of the most power-hungry uses:

  • Netflix 4K: approximately 25 Mbps per stream,
  • Disney+ UHD: 15 to 25 Mbps,
  • YouTube 4K HDR: 20–30 Mbps.

👉 Minimum requirement: 50 Mbps for a household with a single 4K screen.

👉 Multi-screen household: 300 Mbps or more.

With a 1 GiGA fibre subscription, the whole family can watch several 4K films simultaneously without any interruptions.

What about the connected home?

Connected devices, security cameras, smart speakers: each device consumes little power, but when added together, they take a toll on bandwidth.

👉 Minimum requirement: 100 Mbps for a basic connected home.

👉 Ultra-connected home: 500 Mbps to 1 Gbps to manage home automation, video surveillance, and multimedia.

  • Versatility: a single fibre subscription covers all uses (teleworking, gaming, streaming).
  • Reliability: a stable connection, ideal for households with multiple devices.
