Input:
I've been in the technical end of the computing business for over 20 years - done a lot of networking - thought it would be nice to add wireless capability to my home network, so purchased the WAP11 & WPC11 (the pcmcia wireless card that goes with it.) Software installed ok & got it to work. The problem is that the WAP11 has no useful range. As long as you are located in the same room and have "line of sight" with the WAP11, it's ok. If you go out of the room, or any way get out of the line of sight, even the next room, the signal quality goes to poor and the link drops. I have regular, normal wood and sheet rock walls. Packing mine back up for returning...doesn't work as advertised. Very dissapointing.
