Recently bought a wireless usb adapter - realtek wireless 11n usb - and installed the drivers that came with the usb. I have a lot of difficulties trying to connect to my router even though I have very good signal strength and I know the passkey. When I try connecting to the network it usually times out, and other times will connect to the router but will have limited access and won't be able to get me on the internet. It's almost a matter of luck just to get on the internet most of the time... Tried reinstalling the drivers on the cd but I still experience the same issues.
