Now I am working from home I have noticed that my broadband speed drops during the day with no one else at home using it. This morning I did a check at 8am and got 63 Mbps download speed, by 1pm this had dropped to 17.6Mbps. I have at times gone as low as 1 Mbps. Why is this happening? This is way below what I am paying for, how do I get this rectified as it is really disrupting Mircrosoft Teams calls I am doing?
