I own a small cafe/restaurant here in Vancouver, BC. I just recently installed a wireless network, for my customers. I use it occasionally to do some shop-related work. The network itself is completely open, I intentionally did not set a password (the firewalls are up on our PBs). I essentially offering free wireless service, to those that have laptops and PDAs. I am not charging my customers for this service. Now, my question is this: Is there any way that I can monitor how many people are actually using the network at any given time? Is there a function in my PB that can show this? I am just curious to see how many people are actually using the service, without having to count laptops. Our wireless router is made by a company called SMC, btw. Thanks!
