When using Nook App iPad says network connection lost but I can access the internet
I have been at both of my jobs all evening/night (2 different Wi-Fi networks) and I have tried to download books I purchased from Barnes & Noble to my Nook app on my iPad 2. The books appear in my library, however, I still need to download them. This is normal.
BUT, when I try to download the book it immediately states "ERROR Network Connection Lost". I am connected to the Internet, I can access websites, use Netflix, NBC Sports and what not.
I have noticed that apps have been crashing, especially Nook and Facebook.
I have tried the following: restarting the iPad, turning Wi-Fi on and off, renewing the lease, forgetting the network and even resetting the network settings and I still can not download my books. Is there something else I can do? My iPad is only a couple months old.
Thanks
iPad 2, iOS 6.1.3
