The driver for the SpeedStream could be installed. However during installation the default settings are shown (e.g., channel 11), but you can't change them. I couldn't find the file to edit. When you bringup the SpeedSteam Wireless LAN Utility the icon does not appear in the system tray. I also couldn't use browser to access www.speedstream.com -- "The connection was refused when attempting to contact www.speedstream.com".I use to have a Microsoft wireless adapter, but it died so I wanted to try out Siemens. Big mistake. I have PC with Windows 2000 Professional. So I just use the 10/100 ethernet instead.Look elsewhere if you want a wireless connection.
