Hi,
First of all, please let me know whether you have Windows Vista installed on both desktop and laptop computers and whether both computers are unable to connect with Internet through Wireless Networking.
According to your error message, please check whether the wireless router is working properly and if the wireless device's drive is compatible with Windows Vista.
Generally, if the manufacturers of devices don’t provide drivers designed for Windows Vista, we can’t solve the problem just in Windows side. Incompatible hardware, especially basic devices like motherboard, may cause system crash or other serious problems in the future.
To solve the problem solidly, please contact the manufacturer and confirm whether updated driver for Windows Vista is in the works.
Thank you for understanding and I hope the problem will be fixed soon!
