AT&T Fiber connection slowing down every night between 1230CST to 130am CST

I have AT&T FIBER — INTERNET 1000. Gateway/router is Nokia BGW320-505. Desktop is directly plugged to Gateway/router via Lan RJ45 cable. Currently speed seems ok when I run the tracert, I'll try again tonight and post the details. Please let me know if additional information is required. I am not expert in network troubleshooting but can follow the directions and share the details.


Internet speed is very slow midnight. all the household can see the impact at all the online activities are impacted. It get resolved in some time. Sometime in 5 mins, sometime it takes 30 mins. AT&T replaced the Gateway/router last month but midnight internet issue is there. I can feel Gateway/router warm hot which I assume is normal. 


I'll appreciate any help on troubleshooting.
