So I just bought a used Wii U and I'm having trouble getting it to connect to the internet. Both wi-fi and ethernet connections are giving me error messages. I've double checked and both the ethernet dongle and the connection work with both the Wii and Switch so I am confused about what the problem could possible be here.
When trying to connect to wi-fi it gives me Error Code 103-2002
When trying to connect with ethernet it gives me Error Code 103-2007
