The issue lies in managing the transmit power of nearby devices. If you can't control their signal strength, it may end up making yours weaker compared to theirs, hurting your performance. In a clean channel with no interference, lowering power could work, but it becomes difficult in shared spaces like apartment buildings unless you use specific channels or higher frequencies. Even then, signal quality drops noticeably within a few rooms, and reducing power inside the same room as the router might help, though speed can decrease rapidly elsewhere, even in small apartments. For optimal results, ideal setups would feature low-power WiFi access points throughout every room without signal leakage, but this would be costly and complex, and neighbors won't comply.
For a managed AP network, configure your transmit power to keep the invisible "WiFi bubbles" distinct. This prevents clients from constantly switching between APs, avoiding the need to jump to the nearest strong signal. Some systems allow you to define a minimum signal strength before launching a client to another access point. In residential settings, especially multi-family homes, it's best to let users keep their defaults and let routers handle the rest. Most home users lack knowledge of frequency bands or RF concepts. When everyone alters settings—switching antennas, boosting power—WiFi channels become a mess of overlapping signals, causing confusion and interference. It’s tempting to overanalyze with technical controls, but residential environments rarely require it.
I am pushing strongly against this direction. Preventing routers from accessing the signal within the -76 to -80 dBm area is essential. Sharing thoughts on this matter should only be done constructively, without any negative outcomes. No one should suffer because we adjust just this one parameter. Have you tried it before? The channel separation already helps avoid conflicts. This approach ensures each mesh node has its own dedicated channel, allowing smooth operation without interference or time-sharing issues.
Reducing the network’s reach might seem like a problem, but it actually improves performance. The main concern is signal strength—if it weakens too much, coverage drops. This isn’t about complex tech specs; it’s about simple power adjustments. Changing transmitter output is straightforward and doesn’t require altering OS settings, encryption, DNS, or beacon timing.
Most Wi-Fi devices have been using this setting for years, clearly marked as an option. Lowering the power isn’t rocket science—it just means less signal reach. If you’re worried about interference, remember: routers with lower output still won’t block others unless they’re very close. In dense areas, it’s better to keep the signal strong enough to cover without forcing constant adjustments.
This change is common in routers and cards, and it’s safe. It won’t cause new issues—it just optimizes performance. If you haven’t tested it yourself, I encourage you to try it and see how it affects your experience. Let’s keep the discussion focused on practical solutions rather than confusion.
Consider this, everything we aim to share is usually easy enough for most folks. The idea of just leaving it alone is clear—just like explaining that we rely on orbital mechanics rather than rocket science, or saying we use physics to launch rockets isn’t rocket science itself. However, the work behind those concepts is really intricate, and RF engineering adds another layer of complexity beyond traditional rocket science. Focusing on a single aspect like “power” oversimplifies what happens underneath. For most people, leaving things as they are gives a smoother experience overall. That’s the main point we’re trying to convey.
