I have a WRVS4400N Router that I have had for around two years. I am just a business owner and am not well versed in the technical asspects. The router works fine with my desktop plugged into it and other desktops use Linksys N adaptors with no problems. A Mac will work wirelessly with no problem. Laptops will not work unless my desktop that is plugged into the router directly is turned on.
I currently have a new Sony Vaio running Vista Home Premium with an N network adapter built in. It will connect to the router (sometimes) but will never connect to the internet. Many times it will not even connect to the router. If I turn my desktop, that is plugged into the router, then the Sony, and other laptops will connect. But, I always have to turn on the desktop to get them to work. I have no problem connecting the laptops at other access points.
Any suggestions are appreciated. The security mode is WPA2-personal mixed. Wireless isolation is disabled, Encryption is TKIP + AES advanced wireless is all default settings, network mode is B/G/N-mixed. Wirelss SSID broadcast is Enabled. Wireless connection control is all disabled.
