Why can't my PC get on to the internet even though my broad band is working?

Did you call your service provider? they have a code in which you add to your router so that you can use the internet

If you've already been online for some time, there's a little white button on the back of your router that resets it.

Press and hold for 5 seconds then should be online in 20 to 30 seconds after.
