I have had infinity 2 for over a year where I have regularly checked the speed which has been a constant 72mbps download & 17mbps upload. However 5 days ago my download speed dropped to 60mbps and my upload speed has not changed. I contacted the customer services and was told to reset my modem after 48 hours. There has been no change since the reset. There must be a reason for this sudden drop and I would appreciate help in how I can get my original download speed back.
The most likely reason your speed has dropped is because of a noise /crosstalk issue this has caused the DLM to reduce your IP profile to stabilise the line all you need to do is leave the connection alone for up to 2 weeks and once the DLM see the line as stable again it should start to rise again
