Connection loss occurs when using a torrent or streaming via 4K cable.
Connection loss occurs when using a torrent or streaming via 4K cable.
Hello, this situation is tough to describe. I own a QLED TV and have started streaming or downloading 4K movies over my network using a CAT6 cable. The path goes from PC → Gigabit Switch → Router → TV. When playing movies via PLEX or the TV’s Tizen system, the data usage ranges between 70-100 GB with bitrates of 50-60 Mbps. Sometimes the connection drops, and the network card shows a yellow warning that I can’t reset it using any command lines. I need to force a router reset to restore functionality. This also happens with torrent files, especially when downloading large files at once. I’ve looked online for solutions but haven’t found anything specific. I’m unsure what’s causing this because I checked my network bandwidth while watching a 4K movie, and it fell below the expected 8-9 Mbps. My setup includes a Gigabyte Z370 HD3 with 8 GB RAM and an i3-8100 3.6 GHz processor, running Windows 10 Pro. I’m considering upgrading to a better network card if that would help. Any advice would be greatly appreciated.
Only the PC running or streaming the files is impacted. If the network card fails, other devices remain connected to the internet and continue functioning.
I need to verify the exact network adapter model on your board. The Gigabyte Z170-XP SLI uses an Intel I219-V adapter, but the support site doesn't specify the precise model. This could point to a driver issue or require adjusting advanced settings. It should be fixable. Regarding performance, let me know if the issue appears right away during streaming or after a delay—this helps determine next steps.
Start by verifying that all your links operate at gigabit speeds. This should be the first step before adjusting drivers or settings. On your desktop, navigate to Network and Sharing Center, choose "Change adapter settings" on the left, and double-click your I219-V adapter. Verify the connection speed is listed as 1.0 Gbps. After confirming, switch the network cables between your TV and PC, then recheck that the link remains at 1 Gbps. Could you share the router model you have? Based on the setup described, it seems your TV is directly linked to the router, the router to the switch, and your PC to the switch. If so, connecting both devices to the switch might help isolate any routing issues. QoS settings could also be influencing performance.
Network link is shown at 1 gbps swapping cables isn't simple, but I'll attempt it. The router comes from Movistar in Spain, so I need to verify when I'm at home. I plan to connect the PC directly to the router (excluding the switch here). As you mentioned, also link the TV to the switch. I dislike ISP-based routers; if possible, I'd prefer a different one. The switch is a TP-Link gigabit basic model, so I don't think that's the problem. I'll get back to you in a day or two with an update, thank you very much for your assistance.
I own a very simple TP-Link switch that has worked perfectly until recently. There was one instance where it froze during an extremely brief power cut, which I consider reasonable. Please let me know when you have the details—I might not be following this discussion but I can send you a message if you like. It seems like rewiring everything except internet traffic could help. If possible, make sure your router’s settings for ingress/egress prioritization, traffic shaping or QoS are turned off, as well as jumbo frames. Many ISP routers aren’t equipped to handle these features well.
The files reside on the affected drives. Issues occurred when the bad drives caused the network card to stop responding.
It's also typical for torrents to stop downloading when connected to a network drive. The fix involves saving the files locally first and then transferring them to the network drive manually.
