Hello, could ANYONE help me with this please? Obviously I have no clue as to what's going on or I wouldn't be here. I have a Toshiba Satellite L505-ES5034 XP Pro and all of a sudden the Wireless Adapter is really messed up. It's a Realtek RTL8191SE LAN 802.11n. I've tried to Update it and it says it's up to date. I've deleted it and when Windows starts back up it automaticly reinstalls it, but it's still not working as it just sits there and you can see it sorta like jumping like it's trying to work...sorta bouncing in and out. Please help!!
