I am having some of the Same issues. But here is the oddity.... It comes and goes. Sometime Every Single Night that I stream.... somewhere between 10pm and Midnight Central time, my upload speed drops drastically. Download speed remains the same, but Upload just drops out. It will last anywhere from 5 minutes to 45 minutes (occasionally for hours, like tonight). And it only started happening after June 20th, give or take. Before that, I had no problems whatsoever. I am also a Twitch affiliate, and it really ruins the stream when I start dropping 1000 frames per minute. I have Internet 100, and an Arris brand modem, not a Puma. I have switched settings repeatedly, and switched Twitch servers. But the issue persists. Last night for example (7/14/2018)... Started streaming around 11:30pm. Dropped frames and had lag from the start. Played with settings to no avail. At 12:15am, the issues stopped and I had a trouble-free stream for 2 hours. Then the issue reappeared around 2:30am. Dropped 21,000 frames in 15 minutes. Upload speed via Speedtest was 1/3 normal. Download speed remained normal. This issue is really becoming a serious nuisance.
Also tonight Speedtest.net was showing the upload speed issue (only getting less than 2mbs). But DSLreports was showing the correct, expected speed (ie 100/10). But the issue is still occurring... going on 3.5 hours now.
Also today, I checked the outside box, and disconnected two splitters. The cable is coming into the house through a single cable now, rather than 3. I had hopes that would solve the issue, but it did not. I am going to be calling for a Tech to come out tomorrow morning. Was hoping it wouldn't come to that, but alas...
