I've had this problem for about 3 days now and it's got me beating my head against a wall. For some reason that I still haven't figured out, my NETGEAR R6300 Wireless Router keeps rejecting every device I attempt to connect to it, saying the encryption key is incorrect (my PS3 will sit on "Exchanging key information" before failing to connect). We looked into the firmware, and nothing has been changed; the passphrase is the same. Not even my phone can connect to it. But for some stupid reason, my laptop, as well as every other PC in the house, can connect to it just fine. And this isn't the first time this has happened; our Linksys E4200 router started doing the exact same thing after a while, which led to us getting our new modem and current router. It's been restarted and unplugged several times, once for a whole hour, and the problem continues to persist. Our network security is WPA2-Personal if that's affecting anything (we like to keep our network as secure as possible). As far as we know, our router and network hasn't been messed with or penetrated, nor have we changed any settings (it's been untouched for about 2 months). ANY help at all at this point would be greatly appreciated.
