Even a new computer could have a bad CMOS/motherboard battery and you should be able to replace the battery yourself for about $5. A bad battery will create a problem where BIOS settings will fail to be "remembered". See the link below:

How To Replace The CMOS Battery In Your PC(Procedures and Pictures)

After replacing the CMOS battery, if you continue to have problems with the BSky wireless adapter, please remember that third party devices need to bring their own drivers to the party.. Windows frequently doesn't have them on the computer..Therefore, visit the wireless adapter manufacturer's website and download and install the driver for the USB device.. (Usually, there is a CD that accompanies the adapter and that CD should contain the needed drivers. Use the CD if you have it.. If not, the manufacturer's website should have the newest version.)

Hope this helps.
