Wireless

Today, I went to the wireless store and purchased a device to connect my computer to wireless broadband....I installed the software and plugged the device into a USB port and off I went. This seems too good to be true...never before have I been able to watch video from my computer screen....geez....I will try again tomorrow morning just to make sure I have this lightning fast speed.  I actually have 2 weeks ....no hassle trial...all your money back if it doesn't work out....hey...how can you go wrong!!!!
