I have changed the trendline to a Polynomial . I have used an order of 6 as there are many hills & valleys in this data.
The Trendline is showing a stable download speed.
The definition of a Polynomial is below for those who want to know.
A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve. An Order 2 polynomial trendline generally has only one hill or valley. Order 3 generally has one or two hills or valleys. Order 4 generally has up to three.
