OK, so right out of the box mine doesn't connect to the wireless signal that every other device in my house uses (including a couple of 3DS's)... OK, so I always had problems with the Wii in the same spot so I thought maybe the signal was just bad there. But my network was showing 2 out of 3 bars so I didn't think so.
I just found this info on the web:
Ok so far heres what works, entering in everything manually.
1. Go into connection types, Hit "Manual Configuration"
2. Input your SSID
3. Input the correct security type, this is key.
4. Put your password in properly
5. For ip address "Do not auto obtain".
6. open up cmd in your computer, type in ipconfig
7. 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"
8. Enter the rest of your info inside such as subnet mask and default gateway exactly as you see it in your ipconfig.
9. Now hit next, hit configure now for your DNS. When asked about DNS hit "Dont auto obtain".
10. For the first server put in 126.96.36.199
11. For the second server put in 188.8.131.52
12. Hit Next, when asked about a proxy hit no proxy
13. Leave mtu as the default
14. it should work, if not check the ip and that it is the internet ip + 10. Good luck
and so far it is working - it is
downloading the update now
at least. But what has always sucked about Nintendo is the error messages. The stupid error says it "couldn't find the wireless network" (or something to that effect). Well, yeah, it actually could, but something else was wrong. Then in the detailed info it says to check the security setting. What I don't understand is can't they diagnose a little more precisely what the problem is? I mean, if the security setting is wrong or the network is out of range it would be nice to know if that is the actual problem instead of this half-assed handwaving error message that gives you all sorts of confilcting info. It was neither of those in my case since the instructions above (posted by a random user on the Nintendo support forum - not by Nintendo themselves of course) worked.
I'm not looking forward to the Wii system transfer since that means having both touchy systems up and running and on wireless at the same time.
ing A! I spoke too soon. Just went back out to check on the progress and "An error has occured". Yeah, that's really helpful. Now it is back wanting me to reconfigure my network settings again
Now after "checking for update" for like a minute I get error 105-4011. The update never starts downloading. Really useful Nintendo.
