What's the best way to test my broadband speed?

Steve has only been getting 1Mbps when he has paid for 70Mbps. An engineer said there is nothing wrong with his wifi router - is there another way to check?

Recently, I have only been getting 1Mbps from my wifi when it is supposed to be up to 70Mbps. An engineer came round and said there was nothing wrong with the router. His speed checker - unlike mine - showed that it was getting the required speed. He said this test was more reliable as it only used his company's network. Can you recommend a speed checker that is reliable, and not connected to any particular company? Steve

The engineer should have made it clear that you cannot check the speed of your broadband using wifi. When you buy a broadband service from an ISP (Internet Service Provider), they are only responsible for the service delivered to your premises or, at best, to the router.
