Hot key to turn wireless on/off is Function key + F2. You should also have a utility in your Programs list that controls the wireless. Look it up in Help. If you have Vista, open the Network and Sharing Center.
I was playing COD4 on my 1 week old 1555. Then suddenly the internet got disconnected. So when I tried to connect again the laptop could not find any wireless networks.  I clicked on “ why windows cannot  find wireless networks” and I got this message.    [IMAGE] But the thing is i cant find the Wirless Switch on my laptop. my other laptop had it but i cant find it on this  one.    Thanks
