I just got a new Wii U the other day. I have a 3DS, and a Wii. As I am at a campus network, and it requires us to do some computer scan thing, I am unable to connect to the net.
How I got around this with my 3DS is that I added it as a connection, it failed to reach the internet, but it still was connecting to that wireless. I was able to then go through the browser, activate the scanning, and the network recognized my 3DS as a mobile device, and has allowed me in.
I cannot however do this with my Wii U, as the Browser button does not appear on the menu until after a successful internet connection.
Is there a way to get to the browser before successfully connecting to the net?
