Review: No funciona la red de IZZI
Review: La configuration du routeur est facile à réaliser pour programmer les fonctions basiques, aucune compétence particulière n’est nécessaire. Pour la mise en œuvre des fonctions avancées il faut des compétences un peu plus approfondie, mais leur configuration n’est est pas compliquée à réaliser sur le routeur car les menus sont clair. Les performances du routeur sont bonnes aussi bien pour la réception du signal 4G que pour le débit, même avec les antennes d’origine. Le routeur assure couverture Wifi très correcte aussi bien en 2,4 GHz qu’en 5 GHz, le couplage WPS ne pose pas de problèmes. Petites critiques ; pour l’instant je n’ai pas trouvé d’explications sur le fonctionnement « double SIM » , mode normal /secours , agrégation de canaux ?. Ii manque une documentation complète à ce sujet et sur la possibilité de programmation en mode commande, car le routeur peut être programmé en mode AT.

## Questions & Answers

**Q: Is this router AT&T compatible?**
A: We use an AT&T SIM and it works great. Their corporate office will try to tell you it isn’t compatible because of their “switch to 5G” but that’s just because they’d rather sell you their inferior whole home hotspot. I did have to change some settings to get it working correctly, but the dudes at my local AT&T were super helpful with getting me up and running.

En primer lugar decir que vivo en una zona rural, con antena no visible (por poco desde el tejado se ve) a unos 3 o 4 km y hasta ahora tenia un router 4g cat4 de cudy (el mas sencillo de la marca). Gracias a este nuevo router he multiplicado la velocidad de bajada por 3, normalmente tenia unos 6 mb de media y ahora en torno a 15/20 hasta maximas de 70, la de subida suele estar entre 15 y 20mb, antes era pesima, y lo mas importante la estabilidad no pierde nunca la señal cosa que para mi en el trabajo era primordial, no tener que cambiar del wifi al móvil, lo mismo aplica para películas y series ya no se cuelgan, por lo que este router ha sido un salto enorme y ha merecido la pena la inversion. Me daba un poco de miedo no obtener buenos resultados dado el precio, pero estaba un poco desesperado y veia que usando mi movil como router podia alcanzar velocidades mayores asi que me la jugue y un acierto. Añadir que pueden conectarse antenas externas, cosa que haré en el futuro. En definitiva se lo recomiendo a todos aquellos cuya ubicación este en el medio rural con baja señal, os dara velocidad y ESTABILIDAD.
