After installing windows 7 on my desktop computer I am unable to connect to my wireless connection. I have tried multiple installs of the wifi drivers with no luck. The wifi adapter on my desktop is a Realtek RTL8191SU LAN 802.11n USB 2.0 . Everything appears to be working as far as the hardware detecting signals and displaying lights. I am positive I have the correct password too, because I have disconnected and re-entered the password on my laptop and IPhone.
