However, I am planning to get an Alfa AWUS036H (high-power RTL8187L with known sensitivity levels) and an Argtek ARG-U25g (similar to the Alfa, just RTL8187B-based), so I will be able to check the distance where the connection drops (which corresponds to the sensitivy levels). -- Vista: [V]iruses, [I]ntruders, [S]pyware, [T]rojans and [A]dware. :-) -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
