Your mesh Wi-Fi's backhaul is destroying your NAS performance

Using a mesh Wi‑Fi satellite’s “spare” Ethernet port to connect a NAS can quietly throttle performance, according to a practical review. Mesh systems use a dedicated wireless backhaul link to connect the satellite node to the main router. So even if the NAS is physically cabled, its traffic still rides over that Wi‑Fi backhaul, inheriting common Wi‑Fi limits like interference and obstacles. The bottleneck shows up most when backing up or streaming 4K media or large photo libraries. The author says a more reliable approach is to connect the NAS directly via Wi‑Fi only if supported, and otherwise use wired Ethernet for stability.
