When i connect to my jellyfin server to stream/download video/audio the speeds are tied to my internet speed. If my internet speed drops so does the transfer rate from my server. However it seems tied to my internet download speed (which varies from 0.5 to 80 mb/s), not the upload speed(which is usually 2 mb/s), and if i disconect my router from the internet I’m able to react the maximum allowed by my hardware. Is this normal? Or maybe something is wrong, or needs special configuration?
If relevant, I connect to a tp link router, which connects to the router from my isp.
Sounds like some QoS software is also limiting LAN traffic, seeing as it still works if the internet is disconnected. I would look if your router has “Adaptive QoS” or something similar enabled.
