I have had my Wii U for like a month now as I found a new one for really cheap and thought I might aswell buy it now since a price cut can't make it cheaper then €120 anyway probably. So everything is fine with setting up the wii U BUT I have one probablem with the console. It won't connect to the internet!!!! The thing is EVERYTHING in my house can connect to it. I have a PS3,PC,mobile,psvita in the same room as the Wii U and none of them have this problem.

The Wii U can find the router but fails to connect to the internet. So the error I keep getting is 103-2001 and I have tryied to search on youtube for a solution but nothing that helped really.

Anyone else of you who have had the same problem and if so how did you fix it?

Wish Nintendo could just have a enthernet port on it, would make everything so much easier and instead i'm just frustrated on the Wii U and can't enjoy it :(

Maybe entering in the DNS manually helps?

Will try and do that!

I passed the internet icon this time. But it only says I passed the connection test. How do I see if the WiiU is online? (been a while since I used the WiiU)

Because i Keep getting an Error when I go the the E-shop and I can't go into the browser or Miiverse either..

You can buy a Wii ethernet adapter?

o:O that's the first time I heard this. Usually your console should be good to go once you passed the connection test. Is your firmware up to date?

I have 3.1.0 E version and it says it's up to date.(had to download it with my Mobile hotspot D:)

That will probably be my last solution :/. Is the Wii ethernet adapter not supposed to be worse then Wii Fi anyway?(or is their a WiiU ethernet adopter ? ) Also would rather put that money towards a Wii remote controller so I can play some of the Wii games I have missed.

Call Nintendo customer support...they're really good! They got mine online for me.

Solution 1: Tinkering with your network configuration, router settings and learning why system and network administrators tend to hate the human kind.

there are actually two solutions most gaffers will suggest you. they are both pretty similar.

zamkato's solution

1. Navigate to the Wi-Fi portion of the System Settings menu.

2. Tap on or select the option to “Connect to the Internet”.

3. Press X on the GamePad to view your connections and delete every saved connection by tapping on it and opting to “Delete Settings”.

4. Once all connection settings are cleared, return to the “Connect to Internet” screen, select your WiFi network, go through the regular setup process and wait.

5. Once the setup fails – don’t worry, if you’re encountering connection errors, it most definitely will – power down both the Wii U console and GamePad.

6. Reboot the Wii U and return to the Connections portion of the WiFi settings (repeat steps one through three).

7. Tap on your saved Wi-Fi network, followed by “Change Settings”.

8. Enter your network’s SSID (the name assigned to your router).

9. Select the proper security type and input the router’s official password.

10. Change the “IP Address” option from “Auto-obtain” to “Don’t Auto-obtain”.

11. If you’re on Windows, launch cmd and type “ipconfig”. If you’re on OS X, navigate to the Network portion of the System Preferences app, highlight your Wi-Fi network, click “Advanced…”, followed by the “TCP/IP” tab (the “Router” number is used for the “Gateway” field).

12. Input your router’s IP address and add “10″ to the last digit (e.g. if the IP is “192.160.0.1″, enter “192.168.0.110″).
Note: In certain cases, exclude the “10″ – we recommend that you try both.

13. Enter both the Subnet Mask and Gateway (obtained in the eleventh step).

14. Tap “Confirm” and select the option to “Configure” once a DNS settings prompt appears.

15. Change the “DNS” option from “Auto-obtain” to “Don’t Auto-obtain”.

16. Type “4.2.2.2″ for the “Primary DNS” field and “4.2.2.1″ for the “Secondary DNS” field.

17. Tap “Confirm”, ensure that the “Proxy Settings” are set to “Don’t Use” and leave the MTU Value set to the default option (1500).

18. Press B to exit and save and press “Connection Test”.

That's a guide from NeoGAF I found, it seems to work, albeit a bit complicated.
