Hi @osmith0 I hope you don't mind I've started your own thread as it will be easier for the community to follow. I'm really sorry to see you're experiencing slow download speeds.
Can you post your Home Hub router stats and we'll take a look? You'll get them by entering 192.168.1.254 in your browser, if you have a home hub 5 please go to troubleshooting then helpdesk and if it's a Smart Hub go to advanced settings then technical log information.
Can you also check your line for noise. Dial 17070 option 2. Should be silent and best with corded phone and if possible from test socket
Thank you for posting back. Looking at your hub stats your download speed is sitting at 80 Mbps. When you say your download speeds are slow, how are you connected, is this wired or wirelessly?
Do you notice the slow down only happens during the evening? And is this across all devices?
