Para que sea "universal" lo mejor es que elijas tecnologías que cumplan con la norma 802.11"x" Ese de 108Mb no parece ser parte de la norma de 802.11, sino más bien un desarrollo "local" que tiende a funcionar solo con equipos de la misma marca.
Cita: A new proprietary feature called Super G is now integrated in certain access points. These can boost network speeds up to 108 Mbit/s by using channel bonding. This feature may interfere with other networks and may not support all b and g client cards. In addition, packet bursting techniques are also available in some chipsets and products which will also considerably increase speeds. Again, they may not be compatible with some equipment.
En lo personal buscaría algo compatible con 802.11g o
802.11n (si es que ya existe en el mercado)
