I have a Lenovo Ideapad Z500 running Windows 8. Recently I am getting slow download speeds of about 0.3 to 0.5 Mbps. I am on Sky broadband. If I check the broadband speed using a speed checker I get about 14Mbps. I have recently installed a SSD and have had driver problems prior to that and have used Driver Detective to update drivers. I had problems with the Bluetooth drivers but that is now resolved.
