Very good87/100

- Hohe Transferraten per USB
- sparsam im Betrieb
- Umfangreiches und übersichtliches Menü
- Keine Radius-Verschlüsselung
Für ein kleines WLAN-Netzwerk ist die Fritzbox 4040 optimal: Vor allem über kurze Strecken liefert sie hohe Datenraten. Bei viel WLAN-Verkehr oder großer Entfernung zur Gegenstelle hat sie aber Mühe. Die üblichen AVM-Pluspunkte wie übersichtliches Menü und zahlreiche Firmware-Updates mit Verbesserungen und zusätzlichen Funktionen zeichnen auch die kleine Fritzbox aus.
