how I thought my laptop won't work on Wi-fi anymore

How ridiculuos it was.. After finding out the solution to it.. XD

And this was the only reason that was keeping me from going online:

"  FIRST, be sure the wireless is turned on. (MOST laptops have a switch for this.)

It is also possible that your laptop is not compatible with the network modem. (There are several different protocols and they are NOT mutually compatible.)  "

LOL! But thanks to that Y! user i could go on again on wireless connection..
