6 GHz is the entire reason to buy Wi-Fi 7. It is also the reason your router needs a different placement strategy than your old one. Through walls, 6 GHz fades roughly 25% faster than 5 GHz.

| Wall Material | 5 GHz loss | 6 GHz loss | Impact on Wi-Fi 7 |
|---|---|---|---|
| Drywall (single layer) | 3-5 dB | 5-8 dB | Minimal. 6 GHz still reaches through one layer. |
| Drywall (double layer) | 6-10 dB | 10-16 dB | Moderate. 6 GHz signal at -75 dBm through double drywall. |
| Interior wood door | 3-5 dB | 4-7 dB | Minimal. Hollow core doors barely attenuate. |
| Glass / window | 2-3 dB | 3-5 dB | Negligible. Glass is nearly transparent to Wi-Fi. |
| Brick (single layer) | 8-12 dB | 15-25 dB | Significant. 6 GHz may not penetrate reliably in older construction. |
| Concrete floor/ceiling | 10-15 dB | 18-30 dB | Severe. 6 GHz loses 50-75% of usable range floor-to-floor. |
| Metal (ducts, foil insulation) | 20-40 dB | 30-50 dB | Blocked. Metal effectively kills 6 GHz signal. |
Router placed on the ground floor, central position. Approximate coverage zones per frequency band.
Single Wi-Fi 7 router is fine
Central placement covers the whole unit on 6 GHz in drywall construction. The 6 GHz band is also much less congested in dense buildings, which is a real urban advantage.
Single Wi-Fi 7 router works if placed centrally
6 GHz reaches most rooms if the router is in the middle of the home. Older devices fall back to 5 GHz. Works well in open-plan or thin-wall construction.
Single router gives Wi-Fi 6 performance at distance
6 GHz does not reliably reach distant rooms through multiple walls or a floor. Mesh with dedicated 6 GHz backhaul is the right answer. See the mesh guide.
See mesh guide →Mesh required, Wi-Fi 7 or Wi-Fi 6E
No single router covers 4,000+ sq ft with 6 GHz. Tri-band or quad-band mesh with dedicated backhaul is the only option that delivers the Wi-Fi 7 promise across the whole home.
