neeeeed help

Hello.
You are my last chance, i don’t know what to do.
I have notebook with Wi-fi adapter Atheros Ar5006EG last version of drivers installed.
Device works (as windows say).There is dot access D-[name]Link[/name] Dap 1160 dot works normal, my desktop connects with it good.
But not notebook. He simply can’t find it. Windows installed few days ago. If anyone have any ideas, please write here, my head soon will blow up.

Thanks!

my husband says you might need a new router, what kind of router do you have now?
