hi oryamoe:

had similiar problems experiencing when first install ubuntu.

it's bad not aware of firstly going software sources>ubuntu software , selecting options listed immediatly after installation , going updates.

regardless. select open terminal or ctrl+alt+t

need put output of each of following.

since posted information lspci not need post that.
guru here shortly in this. because knowledge still growing know asked following:

code:

iwconfig

code:

lsusb

code:

route -n

code:

uname -r

code:

ifconfig -a | grep -ia9 wlan0

code:

sudo lshw -c network

code:

 lsmod | grep -e rt2

code:

sudo lshw -class network

for last 1 above, put in password created upon initial install. when in terminal asked "password user," enter password. not worry, password not visible.

use 'code' tags of above. these "#" see.
