Stuck on 'Obtaining Address'

[SortOfAZombie]

I got my Nook three days ago, and as soon as it was charged I went through the registration process. Since then, I've downloaded several books from the store, and haven't had any problems. Today however, my Nook decided to stop connecting to my router. It simply says "Obtaining Address" indefinitely. I've tried rebooting it and forgetting and re-inputting the router security code in several times, but to no avail.

My Nook has software version 1.0.1 (What it came with) and I'm using a 2WIRE 3600HGV Router with WPA/WPA2 PSK security.

Can anyone help me out?

Figured it out:

I logged onto my Router's settings and changed the system security from WPA/WPA2-PSK to straight WPA2-PSK. About a minute after I saved this setting, my Nook changed from "Obtaining Address" to "Connected to the internet"

I'll leave this hear in case anyone has a similar problem?
