Q: My MBP will no longer access my network,

it claims invalid WPA2 (which i have checked and double checked). I have cleared my whole keychain, deleted all wireless connections and only managed to connect once i removed all security from my wifi network.

MacBook Pro (17-inch Late 2011), OS X Mavericks (10.9.1)

    What is the make and model number of your wireless router?

     

    Have you reset the device back to factory default settings and reconfigured it again?

     

    Do you have a good utility like WiFi Explorer or WiFi Scanner to take a look at how many other wireless networks that you have around you?

    As a test, try changing the name of the wireless network and password.

     

    If the MBP can connect, leave things as is and set up the other devices to connect to the "new" network.

     

    If the MBP still cannot connect, the you have a MBP issue.....best addressed by posting in the MacBook Pro support area, but we could provide the usual basic troubleshooting steps (which you probably have already done) if you want. The link is below.
