WiFi 6 vs WiFi 5: Is It Worth Upgrading in 2026?
If your router is a few years old, you may be on WiFi 5 (802.11ac). WiFi 6 (802.11ax) — and now WiFi 7 — promise improvements, but is upgrading worth it? Here's the honest answer.
| Feature | WiFi 5 (ac) | WiFi 6 (ax) |
|---|---|---|
| Max theoretical speed | ~3.5 Gbps | ~9.6 Gbps |
| Best for many devices | Struggles | Much better (OFDMA) |
| Battery on phones/IoT | Standard | Better (Target Wake Time) |
| Congested areas | Slower | Handles it well |
| 2.4GHz improvements | No | Yes |
The real benefit isn't top speed
Most homes never hit WiFi 5's limit, so the headline speed jump won't transform a single-device test. The genuine WiFi 6 advantage is handling many devices at once — modern homes with phones, TVs, speakers, cameras and laptops all competing. WiFi 6 keeps them all responsive where WiFi 5 bogs down.
Don't forget the bottleneck
A new router can't make your connection faster than your internet plan. If a wired speed test already shows your full plan speed, a router upgrade only helps WiFi coverage and multi-device performance — not your raw internet speed.
