fuerza de la señal

Gracias por tus comentarios.   I thought the t mobile tech who told me that was all washed up too.  Every other source, and common sense, tell me an external antenna would help..  I hooked one up to my sagemcomm gateway but I think it was too close to the gateway to really help, so I couldn't refute. He had me set set up two networks, one 2.4g only, which seems to help signal consistency, but causes problems when communicating between devices not on the same network.   
 

If anyone has better results with a cell booster, ext antenna, or with the newest gateways (at least one has external ports already) please post it!
