how can i get more wireless connection on my wii?
i don´t have the Wi-Fi connector and i was stealing signal from my neighbor but he moved, now i get only one bar on the wireless scanner and it doesn´t let me get to the internet. My question is how can i get more bars with out buying the Wi-Fi thing?

Best answer:

Do you have broadband internet at your house? Then just spend 20 bucks for the converter.. and it will make your connection wired.
