I'm not a computer nor a network specialist, but I can fly Airbuses :). We are running a small privat house LAN with two WLAN access points, one of them is them modem. I have system administrator rights. Even after changing the password, after a few days somebody is again in our WLAN, we suspect with a iPhone. We would like to see what traffic is going trough our Access Point. How to do that? If a specialist is able to help us, even at some cost, please contact firstname.lastname@example.org Martin

First of all, when you say "password" do you mean the password that you use to log in to your modem/accesspoints? Or do you mean the WEP/WPA key?
I assume you mean the key used to encrypt the wireless traffic. When you configure a wireless key, make sure to use WPA2. WEP encryption can be cracked within a few minutes nowadays and also WPA is less secure than WPA2.
Now for capturing the traffic, have a look at the scenarios on the wiki:

Unfortunetly WLAN Capture is not possible under Windows. You can boot a live Linux (e.g. Linux Backtrack), put your wireless card in monitor mode and see, who is associated to your AP. it looks like this
