WiFi 6E 6GHz band can't penetrate a single interior wall

Homeowners who spend $300+ on WiFi 6E routers expecting faster speeds discover that the 6GHz band — the entire selling point — has dramatically worse wall penetration than 5GHz. A single drywall partition drops 6GHz signal by 7-10 dB more than 5GHz, and a concrete or brick wall effectively kills it. So the 6GHz radio only works in the same room as the router. So what? These buyers paid a $200-300 premium over WiFi 6 routers for a band they can only use within line-of-sight. So what? They either return the router (creating e-waste and support burden) or fall back to 5GHz permanently, meaning they paid extra for hardware they never use. So what? The entire WiFi 6E upgrade cycle becomes a trust-destroying experience — consumers feel scammed by marketing that promised 'multi-gigabit wireless.' This persists because the WiFi Alliance and router manufacturers market maximum theoretical throughput without disclosing real-world range limitations, and because higher-frequency RF physics (shorter wavelength = worse penetration) is a fundamental tradeoff that no firmware update can fix. Reviewers benchmark in open-plan offices, not in typical homes with walls.
