Today I updated to 4.0E (without any problems like some had). After the reboot it said it couldnt connect to the internet. I have two diffrent SSID on my network and none of them worked (D-Link & Netgear routers), Tried to manually set the ip and DNS bit but when testing the connection it never goes out on internet. Tried internet sharing on my iPhone but same problem there. Is there any way to downgrade or update via USB when the next system update comes? My wiiU is softmodded and has worked fine until now.
