Este problema surge cuando las capacidades EHT-PHY muestran compatibilidad con un ancho de banda y el MCS-NSS configurado para ese ancho de banda en particular se completa con ceros y, debido a esto, el controlador obtiene peer_nss como 0 y el env\u00edo de este valor al firmware provoca un fallo. Aborde este problema implementando un paso de validaci\u00f3n para el valor peer_nss antes de pasarlo al firmware. Si el valor es mayor que cero, proceda a reenviarlo al firmware. Sin embargo, si el valor no es v\u00e1lido, rechace la solicitud de asociaci\u00f3n para evitar posibles fallos del firmware.
