AT&T Fiber plan dropping every night
Hi, I have an AT&T Fiber plan in South Florida and every day, like clockwork, I go from 500-700mps download and 500ish upload to...2mps download. Every (Edited per community guidelines) day starting at about 7pm and it continues throughout the rest of the night until after I fall asleep. I know it's not a daytime issue nor should it be a usage issue (I livestream gaming during the day in my off time). I will have solid internet throughout the entire day and then after around 7pm EST it just poofs. I've done all the things that they recommend on the site. I've reset my router both by hand and through their services, I've unplugged and plugged everything in as well. And yet it still does it every night. Now I try to get ahold of customer service though and nobody answers so I get shafted on that as well.
When I do the "internet health test" they have on their site it says that nothing's wrong and that they "couldn't find any issues"
Also when I log into the actual router through the site it gives me over 800 down and 800 up. I ran a speed test through google and Ookla directly after and got the speeds I'm posting.
Please tell me there's something I can do/get someone to do to fix this.
Is there anything I can do about getting it to work at night? Or am I just gonna have to start shopping around for another provider?
