Which is faster?
Ethernet often gives the most reliable result because it avoids wireless interference. Wi‑Fi can still be very fast, especially with modern Wi‑Fi 6, Wi‑Fi 6E or Wi‑Fi 7 equipment.
For speed testing, Ethernet is the best way to check what your broadband line can really deliver.
Which is better for gaming?
Ethernet is normally better for gaming because ping and jitter are usually lower and more consistent.
Wi‑Fi can work well if signal strength is strong, but walls, distance and interference can create lag spikes.
When to use Wi‑Fi
Wi‑Fi is convenient for phones, tablets, laptops and smart devices. It is usually fine for browsing, streaming and everyday use when signal quality is good.
