Wii controllers keep losing connection. What can I do?

I have a Wii and two controllers. In the last few months the controllers lose the connection to the Wii rather often. It's bad enough that we cannot play Mario Kart any more (because one player gets disconnected every few seconds). If I play Super Mario All Stars on my own, it disconnects less often, but when it does, it's always in a jump (which then ends, catastrophically for poor Mario).

I tried replacing the battery sets, thinking that maybe the rechargeable battery sets had issues. But that didn't work.

Nothing in the setup or the room has changed. Connectivity was perfect before this started with rarely a disconnection happening.

I checked for bluetooth devices in the vicinity but bluetooth is switched off in all computers around.

Any ideas?

Solution 1:

I had the same problem when ALL the other problems (batteries, distance, disturbance) was all ruled out. The magic which fixed the problem:

COLD REBOOT!

Beside turning off, also take out the power cable from the Wii-console, wait some 15-20 seconds to make sure all condensators are discharged. Then add power cable back - and voila! Everything is working again!

Solution 2:

It is highly likely that this issue is not the result of interference. Interference is often indicated by erratic or inconsistent behavior rather than disconnection.

It is possible that your battery terminals have become damaged or bent out of position. The act of performing in-game motion controls may be temporarily unseating your batteries, causing the disruption. Rechargeable batteries can sometimes be the cause of this issue due to the fact that some brands differ slightly in size than traditional batteries. Jamming in slightly oversized batteries can bend or push contacts out of alignment. This can result in the oversized batteries working perfectly while any differing brands or types of batteries do not.

My suggestion is to try to use the same batteries or a replacement using the same brand and type to see if this rectifies the problem. It is also possible however that the wii-motes are permanently damaged.
