I know this is addressed as having a different root problem in other threads, but for the past few months, I've noticed that consistently between 6 and 10PM my time, the bandwidth available for my plex stream (whether over Chromecast or a wired connection to my router, or directly to my Comcast modem) drops to around 1.5mbps. Meanwhile, streaming via LTE on my phone is still full quality.
At other times of the day, or via alternate connections as mentioned above, the available bandwidth is more than enough to support multiple original 1080p streams. The server I run the Media Server from has a 100mbps cap with 4TB monthly bandwidth, and is located on a major backbone network. I'm using default settings on the Plex server.
I'm left to conclude that there is some kind of QoS going on on Comcast's end to prevent my streaming from Plex during peak times.
I've read some speculation that the QoS is centered on the port serving the traffic. I would expect either that, or throttling of encrypted traffic -- as I'm accessing Plex via the secure web portal.
I've tried changing the Remote Access port (manually specify) in the Plex Web > Server > Remote Access settings, but when I click "Apply", it fails each time.
I assume that since the Media Server is on my linux server, this is where the port "needs to be forwarded", but as I understand it, my server is having all ports forwarded to it on that IP address. I tried opening the port I specified on the firewall, but the connection still fails.
Can anyone offer me some help figuring this out? I'm really tired of watching my HD streams in 480p
