During speed test, the router abruptly stops broadcasting all SSIDs (2.4 GHz, 5 GHz, 6 GHz and the MLO network). The outage lasts about 3–5 minutes, after which every SSID re-appears and clients reconnect automatically. When I switched to 6GHz only (with MLO fully disabled), I ran the same high-speed test and did not experience any Wi‑Fi dropouts.
