Home computer users predict that wireless networks will have the biggest impact on productivity in the next five years, but say they also put the technology to work to help them have fun.

That's according to the results of an international survey commissioned by Lexmark International, Inc. and conducted by global pollster Ipsos. The online survey of panelists comprised 9,000 tech-savvy home computer users in 18 countries. Ninety percent of respondents said they believe wireless networks will be important to everyday life in their homes over the next five years. Forty percent of respondents said they have already installed wireless networks in their homes and said they use their wireless networks to connect numerous devices and to support a broad range of activities, including 47 percent who said their wireless networks enable them to carry out work-related activities at home.

About a third of the respondents with wireless networks at home said they use them for fun too. Globally, 36 percent said they use their wireless networks to stream music or video and 29 percent said they use the networks for gaming with others. Who's having the most fun? Here's how the country-specific responses stacked up according to the percentage of respondents using their wireless networks for streaming music or video:
