I can't connect to wireless network

I need help from anyone who can. I recently changed from virgin media to sky broadband and since then I've been able to connect to the wireless with my laptop.Other laptops in my house have been connecting except mine. I can only connect with the cord. I have tried all sorts but nothing has worked. I recently visited a friend who uses virgin media and carried my laptop with me hoping it would connect but it didn't connect. Now I can't connect to any wireless network either in my house or anywhere else unless I use the cord. My laptop is Toshiba Equium A100-027. Please I don't know much about computers so please keep your language as simple as possible. Thanks
