To get Tetris Party for the Wii to connect properly (when you’re trying to play with friends), you have to set port forwarding on your router. At least wii did.

Because all routers are different I can’t give specific instructions, but I can give you a general idea.

First, you have to connect to your router. To access the router interface, type the IP address of the router in the address bar of your web browser. If you don’t know the address of your router, you can get it from your computer. Go to Start–> Run–> Type CMD and hit enter –>The DOS window will open. Type ipconfig /all and hit enter. The address of your router will be the same as the default gateway. Ususally it is 192.168.1.1

Now, you have to get the IP address of your Wii. Get it from the router. The router should have a function called “DHCP Clients” or “Connected Devices” or “Client List” or something like that. Look for the Wii. It’s usually 192.168.1.3 or .2 or .4 or something.

Next, you have to find the router’s Port Forwarding function. It should be in the Firewall section of the router settings. It may be called something else. On mine it’s called “Virtual Servers.”

Add a new entry to this section. Call it Wii or something similar. Set the IP address to the same as the Wii, and then for the port range, enter 1 for the low end and 65535 for the high end. Your router may not allow 65535. If it doesn’t, pick a lower number like 65534. The type should be UDP only.

That should fix it. You may have to restart your router or the Wii for everything to work, but I didn’t. If it still doesn’t work then you probably have to place the Wii into the router’s DMZ area, and that’s typically not a good idea.

Now it is possible that next time you turn on the Wii it will get a different IP address from the router. So if you get the connection errors again, go back to the router and use it to look up the Wii’s IP address. Then go back to port forwarding and change the settings to point to the new IP address.
