Help with Wii U

I'm getting the following errors:

105-4011
105-4207
105-4400
105-4206
108-0144

It either says "An error has occured" or "Cannot connect to Server" or "Wifi is lost" sometimes. I tried everything from moving from location to location, turning off my tv, Wii, even my phone, even putting it near the console.

Do a manual connection.

Go into connection types, Hit “Manual Configuration”.
Input your SSID.
Input the correct security type (this is very important, obviously).
Put your password in properly.
For IP address “Do not auto obtain.”
Open up cmd in your computer, type in “ipconfig” (Window computers, OSX users view message at bottom).
Now input that IP address but add 10 to the last number so “192.168.0.1″ will be entered as “192.168.0.11.”
Enter the rest of your info inside such as subnet mask and default gateway exactly as you see it in your ipconfig.
Now hit next, and then hit configure for your DNS. When asked about DNS, do not autoobtain.
For the first server put in 8.8.8.8.
For the second server put in 8.8.4.4.
Hit Next, and DO NOT set a proxy.
Leave MTU as the default.
It should work, if not check the ip and that it is the internet IP + 10.

Try that?
