I just bought a Wii, I live in vietnam and you buy them chipped at the store (i think so because it plays copied games)

It is a japanese wii. I have a few questions.

1. Can I access the internet without it affecting the hack? I'm not really sure what the wii connect 24 really is... but if i update the wii in anyway, is there a way they can find out and kill my chipped wii? or just simply kill my chipped wii myself?

2. I managed to set up the internet... well not really. After selecting my wireless connection and entering my password the wii was doing something (downloading, connecting to the internet, updating... i'm not sure) BUT my dog unplugged the wii!! now i cant even get passed the first window of the internet thing.... what can i do to?

Thanks a lot for your answers!!!
