Vista - Wireless internet adapter

i use the netgear wireless adapter to connect to the internet, the router is also netgear.
just to use the internet i have to go into my Device Manager and uninstall and disable my netgear adapter over and over till i get it to work randomly, sometimes it works on first restart sometimes i do it for like 30 min and then it works.

its strange that it works though just randomly when it wants. is there a fix to this?

i have installed the disk followed instruction from front to back and the box said that it is compatible with vista, what is the problem and how do i fix it?

Please give more details about particular Netgear model numbers and information on the computer you are using with the Netgear hardware.
