I went through the process of going from: NC1 to NB1, downgrading NB1 to MK2, rooting, then using the NC1 keeproot. I have no idea if my WiFi problem has to do with the process I listed but I noticed when I connect to my network it immediately goes to disabled, when my WiFi disconnects and I go to the WiFi menu it doesn't show the list of connections around my area. I tried reading around finding my issue but didn't quite find what I needed only "fixes" I tried was un-checking the auto network switch and going to the service mode screen and turning off wifi power save mode.
Any help would be greatly appreciated. Thanks
