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.<\/p>\n\n\n\n

So, is the Ethernet cable still useful today? Short answer: yes\u2026 but it depends heavily on your use case.<\/p>\n\n\n\n

Wi-Fi and Ethernet: two completely different approaches<\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

In other words, Wi-Fi prioritizes freedom of movement. Ethernet prioritizes pure performance.<\/p>\n\n\n\n

Data transfer rates: beware of marketing figures<\/h3>\n\n\n\n

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\u2026 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.<\/p>\n\n\n\n

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:<\/p>\n\n\n\n

1 Gigabit Ethernet<\/h4>\n\n\n\n

Long considered the home standard. Sufficient for most conventional fiber connections.<\/p>\n\n\n\n

2.5 Gigabit Ethernet<\/h4>\n\n\n\n

It has been very popular for several years on modern motherboards, NAS devices, and routers. It becomes particularly attractive with multi-gigabit fiber subscriptions.<\/p>\n\n\n\n

10 Gigabit Ethernet<\/h4>\n\n\n\n

Still relatively high-end for home use, but already common in professional environments, large network transfers, and certain advanced setups.<\/p>\n\n\n\n

Wi-Fi 6, 6E, 7\u2026 where are we in 2026?<\/h3>\n\n\n\n

Modern Wi-Fi has little in common with that of ten years ago.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Wi-Fi 6E introduced the 6 GHz band, which is much less congested than the historical 2.4 GHz and 5 GHz bands.<\/p>\n\n\n\n

Then came Wi-Fi 7, a true technical marvel. Larger channel widths, better band aggregation, reduced latency, enormous theoretical speeds\u2026 under good conditions, the performance becomes truly impressive.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Why gamers still prefer cable<\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

This may not be a huge difference in a casual solo game\u2026 but in a competitive FPS or a professional environment, it can quickly become noticeable.<\/p>\n\n\n\n

Ethernet cables: which one to choose?<\/h3>\n\n\n\n

Good news: there's no need to fall into marketing excesses.

In 2026, the Cat5e<\/strong> still remains perfectly capable of handling Gigabit Ethernet in a huge number of installations.<\/p>\n\n\n\n

THE Cat6<\/strong> often constitutes the best compromise for a new installation.<\/p>\n\n\n\n

THE Cat6a<\/strong> It becomes interesting if you are aiming for 10 Gigabit over longer distances.<\/p>\n\n\n\n

The famous Cat7<\/strong> And Cat8<\/strong> They do exist, but they are often oversized for typical home use.<\/p>\n\n\n\n

To put it simply: for the majority of individuals, a good quality Cat6 cable is more than sufficient.<\/p>\n\n\n\n

Verdict: Wi-Fi or Ethernet?<\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

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".<\/p>\n\n\n\n
