Thread: realtek 8192se - scan properly but doesnt connect

hi everybody.
i've been searching around trying solve issue havent been able working.

problem wireless card on laptop detects wireless networks can't connect them. think it's os problem cause have dual boot windows 7 x64 , hadnt trouble since bought it.
it
when i'm trying connect network asks me password 'wireless network authentication required'. i've checked tons of times password writting right one, keeps me asking if put wrong.

disabled kind of wireless security on router (first had wpa2-psk) , tried connect again. had remove network manager's entry of network stop asking me password.
once tried connect without asking password (because @ point wireless open) kept trying connect several minutes until disconnected.

suspected there problem dhcp. couple of months ago, tried connect command-line. went right until had ip address. @ point dhclient hanged requesting address.

tried connect network using statc ip address. network addres 192.168.2.0 put address didnt collided of hosts connected it. again, kept connecting while wireless open or asking password when wasnt.

seems odd me, cause connect neighbours' wireless network , havent trouble connecting university's.
