Sry you are using what flavour of SL and what wifi card.
Mine in 3.3 mini now / 3.4 loop3 / 1.0 BE all show % from 0 up to 90% in all of them.
1.0 BE you can click the knetworkmanager and should show you a nicer layout for the wifi with several tabs.
You can alternatively post / copy+paste the "lspci" info here to get a idea if the driver is working.
As root in terminal type
and copy /paste to here.
You can also use " net-setup " as root and follow the info there if not wanting to use knetwrokmanager.
Then type the ifconfig as the message there at the end say's and see if you have a valid IP.
