    Hello Everybody,

    I just got a job at a School district that has an extremly old and basic network setup (No Firewall, only 2 accounts on the server Student and Teacher). They have two small buildings that have 1 wireless router on each floor about in the middle of the hallway.

    I am having a strange issue I haven't seen before with a windows 7 laptop that a few of the teachers in the district are having. They can see the wireless router on the network but everytime they try and connect it says "Windows Cannot Connect or is Denied Access". All the other laptops in the building connect fine.

    Heres what I have done so far.

    -Power cycled the router, nothing.
    -ipconfig /release, and renew, nothing.
    -Getting closer to the router and connecting, nothing. (Also tried with a differant laptop in the room and it could connect no problem which confused me more)
    -Updating the network card.(says it has the latest updates)
    -Re-entering the network key, nothing

    What I haven't tried is setting up manually a static IP. But do I need to do that? And if so how do I know which IP to give it is there a way I can generate a list of all the IP's on the network?

    I appreciate any help, I AM STUMPED!

    Hello DMH

    In regard to your issue, could you please provide us with an ipconfig /all from a computer that is connecting ok and also an ipconfig /all from a computer that is not connecting ok. This is just for our reference to start off with.

    What OS and antivirus software are these laptops using?

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.
