I just thought I would add that I bought a Kobo Touch today, downloaded the software and configured everything, only to find that it is the only device I own that will not connect to my wireless router.
I have a D-Link DIR-825 router using WPA with a 64 character hex key.
I've entered the password a half-dozen times, so I know I'm not entering it incorrectly.
I tried both scanning the networks and typing in the SSID manually.
I've reset the device to factory defaults and it still doesn't work.
Unlike others that at least get it to work intermittently, I'm at a complete loss.
The error I get is "incorrect password". It finds routers, so I know the wifi adapter is working in the device, so it must be a software issue.
I'm at a total loss here.
