Keeps showing loss of connection

It's either not establishing a connection with the Wii, or it's batteries need changing. I personally have never had to connect a balance board with the Wii for the first time, I only played with it at my friend's house.

Open the battery cover of the Wii Balance Board, you'll see a red "Sync" button. On your Wii itself, if you lift the SD Card slot you will also see a red sync button. Press the sync button on both the balance board and the Wii and it will connect.

If you haven't already tried to replace the batteries, do this (if you have, this is useful information to include in your problem description :D). If that hasn't worked, you may need to re-sync the board with your Wii.
1. Power on your Wii console (there is no need to power on your balance board at this time).
2. Open the SD card slot cover on the front face of your Wii to reveal the red Sync button on the Wii.
3. On the bottom of your balance board, remove the battery cover to reveal the red Sync button on the balance board.
4. Press the Sync button on the balance board (there is no need to keep it depressed; simply press and release). You will notice the power LED on the power button on the balance board blinking.
5. Now press (and release) the Sync button on the Wii console. After the LED stops blinking, the Sync is complete.
If this does not fix your balance board, it may need to be repaired or replaced. Contact Nintendo and provide warranty information if applicable.
Good luck!

First, the batteries in the Balance Board could simply be dead or need to be recharged.

After ensuring the batteries are good, if it still does not communicate with the Wii, take the battery cover off the balance board, you will see a small red button. On the front of the Wii unit itself, there is also a small red button. Press them both within a short amount of time to sync them together. From this point forward, they should be able to talk to each other.

Open the battery cage in the Wii Balance Board. If the light won't blink, change the batteries.

If it does, but doesn't change to a solid light, open the SD Card slot in the Wii itself. Press the red button. Then, quickly open the battery cage in the Wii Balance Board and press the red button there as well. Done. This is what's called "syncing". This method also works in the Wii Remote's battery cage.

did you try resetting it with the little red button where the batteries go

Hi, thanks for using Fixya!

• Open the SD card slot on the nintendo wii, open the battery panel on the wii balance board.

• Press the two red sync buttons on the wii console and the balance board and hold for 3 seconds.

• The blue light on the back of the wii balance board should flash for 5-10 seconds and then stay blue.

• If this doesn't work then try changing the batteries and trying again.

If it still isn't connecting then the problem is something a proper nintendo expert will have to help fix.

Thanks, I hope I have been of assistance.

You have to sync it up to the Wii. Open the little compartment under the reset button. Press the little red button, and press the red sync button on the balance board. Which can be found were the batteries are placed.

make sure the battery charger is connected, and that the port connections are tight, other than that I would say you have a faulty charger.

You need to reconnect it to your Wii by pressing the RED Connect buttons on the Wii and Wii Balance Board.
