It appears that your Wii console's Internet connection may be affected by wireless interference. Try the following:
- Change your wireless router's channel to 1 or 11
Changing the wireless channel on your router may help. Most wireless routers have a channel range of 1 through 11. The best channels to try are usually 1 and 11, as they do not overlap with other channels. Typically, the channel settings for your router will be found in the router's main "Wireless" tab.
- Where is your wireless router located?
Move your router away from walls and off the floor and try to place it in a central location in your home. Also, keep it away from metal objects such as metal filing cabinets which can cause interference.
- Look for other devices
Noise from cordless devices (cordless phones), or wireless electronics (wireless keyboards, headphones, cell phones), especially those using the 2.4GHz frequency, can interfere with your wireless signal. Also, older microwave models can cause wireless interference. Avoid electronics that use the 2.4GHz frequency, instead look for devices that use the 5.8GHz or 900MHz frequencies.
