I'm having a similar issue with a DLink DIR600. I very carefully wrote down all the information when I set up my router. However, I'm unable to connect wirelessly. I've tried every network security key combination that is close to what I've written down but nothing is working. Is there a way to change the network security key without resetting the router back to default and starting over? I opted for WPA.
I am changing from a DLink G router to an N Router. Most of my computers use still use the G frequency. Could this be an issue? The salesman told me it shouldn't matter.

I ran the CD using a Windows Vista pc. I also saved the settings to disc but where did it go? Can't find the file.
TIA
