Reimaged, laptop sees wireless, won't connect

Hello,

I have a Gateway laptop that is about 3 years old. It worked perfectly for a long time and then all of a sudden I kept getting kicked off our secured wireless network. My husband would be sitting right next to me with his laptop and wouldn’t be affected.

I have reimaged the computer twice and I can still SEE the wireless connections but for some reason can’t connect. I have no problems when it’s connected to the wired network, and have no other issues with the laptop. My husband has checked everything with all the hardware/network connections and says they’re all fine because everything works perfectly with our two other laptops.

Any suggestions?

Thanks!
