I need some help here to deal with the wifi issue on Vista only. There are 5 desktop pc at my home. Among which are connected on the network through ethernet cable and 2 are on wifi. My dad bought a Vista laptop. I had added the laptop to the wifi router. To extend the router bandwidth I had added a hub at the central part of home. This hub supports wifi network to get better range. Now in Vista the wifi is connected but the connection drops in between. I am not able to figure out the reason. When ping a website I am getting request time out error in between and it keeps on failing. I had tried a number of different thing to configure the router but somehow it is not working. Any idea how to fix the same.
