If your broadband is not working then check that your router connection lights are on. Also, if you are using a laptop, that you haven’t accidentally turned off your wi-fi connectivity. Try rebooting your router and/or computer and see if that solves the problem. Also test your phoneline to make sure that you have a dial tone. If you don’t have a dial tone, then it would suggest a fault with the service provider, so contact them (on a mobile!) for advice so they can run some checks.
Check with your service provider as to what your speed should be in Mega Bytes Per Second (mbps). The speedchecker website test will then confirm what you are actually receiving.
