Wifi not connecting?

[2sneaky4u]

Ok I am attempting to root the NC. I got everything loaded and when it comes up I get the android screen and it loads to the setup. I think ok I must have lost the data during the install. so I go through and enter the info and connect to my home wifi. I enter my new b&N account info and hit submit and I get " a network-related error occurred. you may have lost connectivity to the local wireless network" error. I now cannot connect to any network. has anyone had this issue I have not seen this issue on any other post but I could have missed it. any help would be greatly appreciated.
