Maybe the dlink is set for WPS (wireless protected setup) and gave your system a key. That might require intervention. But perhap a button lit up and flashed on the dlink router, and the owner pressed that button to silence it.
Or perhaps the dlink is setup as part of a sting operation. -- AT&T Uverse; Zyxel NBG334W router (behind the 2wire gateway); openSuSE 12.1; firefox 9.0.1
Thanks for your reply, the router is set to WPS because I now have access to it does that mean that WPS can in certain circumstances give away the WPA key? if so what are those circumstances as I have not been able to replicate the situation and connect another laptop the same way, what do you mean by "setup as part of a sting operation"?
I have always disabled WPS as a security hazard. So I don't know the full ins and outs of it. It does look to me that you have demonstrated one of the security hazards. -- AT&T Uverse; Zyxel NBG334W router (behind the 2wire gateway); openSuSE 12.1; firefox 9.0.1
