Asymmetric Digital Subscriber Line, or ADSL broadband, refers to one of the three widely available types of broadband connection (fibre, cable, and ADSL). It will often be the slowest speed that an ISP will offer and is becoming less common as the UK’s fibre network works its way towards becoming our default connection.
ADSL will generally provide download speeds of around 10Mbps. In theory, this is enough to watch Netflix, which requires a minimum of 5Mbps. The issue, however, is that the low speeds that ADSL provides doesn’t leave viewers with much wiggle room.
If other people in your home are on the network at the same time, or bandwidth is being throttled during peak hours, streaming could become unviable. You also won’t be able to stream any 4K UHD content, as that requires a minimum download speed of 25Mbps.
That’s why we would always recommend going for something a bit punchier - around the 40-50Mbps range - which will allow you to watch your favourite films and shows without interruption.
