I cannot connect to wifi with my Toshiba laptop model c660_2D8

Could be your router, could be your laptop. If other devices can connect to your wifi, then it is your laptop, if not, then it is your router. If it is your router, check all physical connections and power of course, make sure it is plugged in. If it is your device, and all other devices cannot connect to the wifi at your place either, but can connect at other places with wifi, it is either your router, or your ISP. If it is your laptop, then you can perform a system restore, which may correct the problem. If that doesn't work, look up the support/drivers section for your particular model from the manufacturers website, down the drivers for your laptop Wifi card, and reinstall the drivers. The support section at the website will also show you how to perform a system restore.

I haven't had that trouble but I just wanted to mention some of the WLAN analyser apps can be quite useful.

• There is a wireless switch on you laptop. See if its turned on.
• Most wifi connections are connected to DHCP service either in router or after the AP. Make sure your laptop does not have static ips : this can help you: http://www.computing-tips.net/Change_IP_Address_Windows_7
  

there is no wifi card built in to the laptop as standard but it is easy to use a usb wifi adapter to allow a wifi connection

In connecting through a wifi, there are two factors to consider. (1) Wireless Router broadcast and (2) Wireless Receiver.

Make sure that your network router is broadcasting wireless internet or wifi. Also, you have to know if you need a pass key or password in order to connect to the wireless network.

Now, given that there is a wifi spot, your laptop should automatically recognize the wifi broadcast and negotiate connection without your intervention. This will only happen IF AND ONLY IF your laptop has a wifi radio receiver and that it is TURNED ON. When it is turned ON, it will connect you immediately if the network has no pass key set. If there is, then you have to enter that key when you try to manually connect it. (Right click on wireless network icon on system tray. Then it should say: Wireless Network Available. Then Click CONNECT)

To turn your wifi radio receiver ON, slide a switch button to ON position depending on your laptop model. If you dont have that kind of switch, look for the wifi icon printed in the keyboard keys. In some laptop, it is in F2. Now Press FN+F2 to turn wifi radio receiever ON and OFF.
