The Five Common Failures — ReynaNets — Home Wi-Fi Networks

Dead zones, interference, band steering, old clients and DNS explain most home Wi-Fi complaints.

Dead zones: a room with weak signal. Move the router 1–2 m, add a mesh node, or fall back to 2.4 GHz, which reaches farther than 5 GHz, which reaches farther than 6 GHz.

Interference: strong neighbor networks or a microwave on the same channel. Scan with a Wi-Fi analyzer app, move to a less-used channel, and narrow 2.4 GHz to 20 MHz.

Band steering: one SSID advertised, but the client refuses to move to 5 GHz. Split the SSIDs temporarily, or disable the smart-connect feature if it misbehaves.

Old clients: a Wi-Fi 4 phone or legacy printer drags the 2.4 GHz cell down. Put legacy devices on a separate guest SSID limited to 2.4 GHz.

DNS: pages load slowly while the speed test looks fine. Change the router's DNS servers to a fast public resolver and clear the client cache before touching any Wi-Fi setting.

Dead zone → move hardware or add a node.
Interference → change channel, narrow to 20 MHz on 2.4 GHz.
Band steering → split SSIDs or disable smart connect.
Old clients → isolate them on a 2.4 GHz guest network.
DNS → change resolver, then retest browsing.
