Networking :: newbie cant get online

i still havent been able to get this...
any other suggestions you might be able to give?

i have tried using
# wpa_password my_ssid my_very_long_password

and replacing the line
psk="my_very_long_password"
in wpa_supplicant.conf with the psk gnerated by wpa_password

and tried adding the line
proto=WPA

and commenting out the line
pairwise=TKIP

and all the different combos of the above changes in wpa_supplicant.conf. none worked.

do i need to reboot inbetween making each change to wpa_supplicant?
