For a long time, the debate was simple: if you wanted the best performance, you needed an Ethernet cable. Wi-Fi, on the other hand, was mainly reserved for smartphones, tablets, or devices that couldn't be neatly wired. But it's 2026, and things have changed dramatically. Between Wi-Fi 6, Wi-Fi 6E, the increasingly widespread adoption of Wi-Fi 7, and the gradual rollout of Wi-Fi 8, wireless networks have never been faster.
So, is the Ethernet cable still useful today? Short answer: yes… but it depends heavily on your use case.
Wi-Fi and Ethernet: two completely different approaches
Ethernet relies on a physical connection. Your data travels through a cable directly between your device and your modem, network switch, or router. This provides an extremely stable connection, very resistant to external interference.
Wi-Fi takes the opposite approach. Here, there is no direct wired connection: data travels via radio waves. This is obviously much more convenient for everyday use, but it introduces several invisible constraints: distance, walls, nearby devices, electromagnetic interference, and frequency saturation.
In other words, Wi-Fi prioritizes freedom of movement. Ethernet prioritizes pure performance.
Data transfer rates: beware of marketing figures
On paper, modern Wi-Fi technologies boast impressive figures. A high-end Wi-Fi 7 router can advertise several gigabits per second combined. That sounds enormous… until you look at the actual performance.
In practice, a Wi-Fi network is heavily dependent on its environment. The distance to the router, the thickness of the walls, the number of connected devices, and even the neighbors can significantly affect speeds.
Conversely, Ethernet generally offers much more predictable speeds. A Gigabit Ethernet port will very often deliver performance close to 1 Gbps under good conditions.
Today, several Ethernet standards are commonly found:
1 Gigabit Ethernet
Long considered the home standard. Sufficient for most conventional fiber connections.
2.5 Gigabit Ethernet
It has been very popular for several years on modern motherboards, NAS devices, and routers. It becomes particularly attractive with multi-gigabit fiber subscriptions.
10 Gigabit Ethernet
Still relatively high-end for home use, but already common in professional environments, large network transfers, and certain advanced setups.
Wi-Fi 6, 6E, 7… where are we in 2026?
Modern Wi-Fi has little in common with that of ten years ago.
Wi-Fi 6 has greatly improved the simultaneous management of connected devices, which is particularly useful in homes filled with smartphones, consoles, televisions, PCs and connected objects.
Wi-Fi 6E introduced the 6 GHz band, which is much less congested than the historical 2.4 GHz and 5 GHz bands.
Then came Wi-Fi 7, a true technical marvel. Larger channel widths, better band aggregation, reduced latency, enormous theoretical speeds… under good conditions, the performance becomes truly impressive.
As for Wi-Fi 8, we start hearing about it in 2026, but its deployment remains gradual and largely focused on improving stability, network coordination and very busy environments.
Why gamers still prefer cable
Even with an excellent wireless network, cable retains one very difficult advantage: latency. For video streaming, watching Netflix over Wi-Fi rarely poses a problem. But for certain sensitive uses, every millisecond counts.
Competitive gaming, cloud gaming, professional video conferencing, live streaming, home servers, NAS or massive file transfers: these are areas where Ethernet often maintains a tangible advantage.
Ping is generally lower, more stable, and above all, less prone to sudden variations.
This may not be a huge difference in a casual solo game… but in a competitive FPS or a professional environment, it can quickly become noticeable.
Ethernet cables: which one to choose?
Good news: there's no need to fall into marketing excesses.
In 2026, the Cat5e still remains perfectly capable of handling Gigabit Ethernet in a huge number of installations.
THE Cat6 often constitutes the best compromise for a new installation.
THE Cat6a It becomes interesting if you are aiming for 10 Gigabit over longer distances.
The famous Cat7 And Cat8 They do exist, but they are often oversized for typical home use.
To put it simply: for the majority of individuals, a good quality Cat6 cable is more than sufficient.
Verdict: Wi-Fi or Ethernet?
The truth is that by 2026, Wi-Fi has become extremely efficient. For a smartphone, a laptop, a Smart TV, or typical home use, it perfectly meets the needs of most users.
But Ethernet has absolutely not disappeared.
When it comes to achieving a maximum, stable, predictable connection with minimal latency, a wired connection maintains a significant advantage. Therefore, the best choice isn't necessarily "Wi-Fi or Ethernet".
It's often… Wi-Fi for mobility, Ethernet for critical devices.
