Trying to connect through the only dual band device I have at the moment, my Dell Precision M6400. Router is a ASUS RT-66U (the "R" version from Best Buy). Passkey and encyption is setup the same between 2.4 Ghz and 5 Ghz bands Encryption: WPA2- Personal AES-CCMP on both bands. 2.4 Ghz only asks for the passkey, which is a human readable password, 8 characters total with some numbers. It's the same passkey for the 5 Ghz band. When I go to connect to the 5Ghz band, I get the following dialogs: Looks good so far... next dialog - and I don't see this with the 2.4 Ghz band! Number has been changed to protect the innocent. If I enter an invalid number, it won't go any further: 8 number key entered successfully, next dialog: Ok then, the bottom of the dialog has a really long sting of characters... If I accept the default, or type in the actual pass key, I get the same results - configuration FAIL!!! And the result... either way (accepting the default password key, or entering the one I have setup for the router) : FAIL: What might I be doing wrong???
