The recent update to Wii's Internet Channel caused some things to not work any more, for example the BBC's iPlayer service for people in Britain.
The BBC addressed this in an FAQ on their website:
The latest Nintendo Wii software upgrade has caused BBC iPlayer to cease working. Users that have not upgraded can continue to use the BBC iPlayer website.
We are currently investigating and hope to resolve these issues with the BBC iPlayer. Later this year we will be launching an all-new BBC iPlayer designed specifically for the Wii.
