The wii was working fine then all of a sudden there was no power going to the console. I unplugged it, waited awhile then plugged it back in again, still no power. Can it be the power cord?

Reset the AC adapter by following steps below.

1. Unplug the Wii AC adapter at both ends (from the back of the
Wii system and from the wall outlet or power strip).

2. After you've waited a full 2 minutes, plug the AC adapter back in on both ends and check to see if the power light comes on.

Your wireless router may need to be power cycled, or the connection settings have changed.
Power cycle your router; redo the connection settings on the Wii and try again.


Did this connection used to work but has suddenly stopped? "Power cycle" your router and modem. To do this, unplug both the modem and the router from the power outlet. Wait a few minutes, and plug the modem back in. Wait a couple of minutes for the modem to initialize, then plug in the router. Try to connect the Wii, Nintendo DS, or Nintendo 3DS online and test for proper response

• Erase your old connection settings on the Wii and set up a new one, as your router's settings may have changed since you last connected.

You are not getting the correct voltage into the Wii, this can happen one of three ways. (1) The power converter you have is not converting the power correctly, (2) running on converters are not exactly matching the correct voltage and wattage has strained your power supply and damaged the Wii, or (3) the power supply itself just failed as a result of any number of normal electrical conditions.

Did you have a power surge? Unplug the power supply from the wii and the wall for five mins. Then plug it back in and try it out. Have heard of this working for some people.

Unplug your wii from the wall and the console, wait about 20 minutes. Then plug everything back in and try it.

I just tried something someone suggested in an earlier post. I unplugged the console from the power source waited 5 minutes plugged it back in and now it works again. Hopefully this will work for you as well.

When this same thing happened to me, I unplugged the Wii power supply from the wall (not just from the back of the Wii) and let it sit unplugged for about 10 minutes. When I plugged it back in, everything was fine.

unplugg everything from the back of the wii and unplugg the power/ac adaptor form the wall wait 2 minutes and plugg everythnig back in.....hopefully this works for you it worked for me!!
