Some thing funny happened to my Wii before I moved. At my old house the connections were working perfectly without any accessories or anything. When I moved, the connections were getting stupid and most of them were locked. Please help! ???
Hmm. Are you using your own internet to connect or are you using somebody else's? From what you've said it sounds like you were & are using somebody else's internet, only way to fix this is to get a router & set it up with your Wii or get/make a cantenna or something similar and hope that the connections will be better. Also the only way to access the locked ones is if you know the password or use a program to crack it.
You should be able to access the Wi-Fi from your house then... Are you sure you've set it all up properly? (In the Wii settings too). If you already have then I don't know what the problem is, just wait for another member to help you
This just means that your old neighbors had unsecured Wireless connections that you used to connect to. Now your new neighbors are smart and have at least some security, locking you out of their connection. The solution is to setup your own wireless router, and password.
If it's from your old house I suggest re-configuring the set up. The ip adresses would be changed I presume. And as TrithRR said-new neibours are smart
