I would reccommend searching the forum, because many, many people have these same exact problems all the time.
Trying to connect to the Wii Shop channel and its just sat on the connecting, please wait screen - its been like this for about 5 mins. this is the first time I have tried to connect to the shop, i can get my weather forecast and i have all available updates. any ideas?
log into your router and change the default channel to either 1 or 11.
That should work.
