Why are broadband speeds sometimes slower than advertised speeds?
There are a number of reasons why you may not receive the broadband connection speed advertised by ISPs.
One main reason is that for most broadband customers the maximum speed available declines the further you are from the telephone exchange.
Other factors which can affect broadband speeds include the quality of the customer’s line, the capacity of the ISP’s network, the number of subscribers sharing the network, and the number of people accessing a particular website.
