I’m setting up a dedicated Plex server and need some advice regarding networking. My current setup includes multiple devices streaming 4K content simultaneously, and I’m noticing occasional buffering. I suspect my network switch might be a bottleneck.
I’m considering upgrading to a high-performance network switch/module that supports Gigabit speeds or higher. Does anyone have recommendations for switches that handle multiple high-bandwidth connections efficiently? Also, would features like link aggregation or VLAN configuration help improve streaming stability in a Plex setup?
Any suggestions or insights from those with similar setups would be greatly appreciated!
Just about any modern switch with 1gbps ports will do the job. A 4k remux stream can peak around 120mbps so it still takes quite a few to saturate a 1gbps link.
Link aggregation at a simplistic level sends data streams across different links. It won’t split an individual stream across multiple links. It’s beneficial if you have a server sending data to multiple clients. You’d need to have quite a few streams running before link aggregation would be required.
VLANs segment networks and are generally used to isolate different parts of the network. You’ll need to have a VLAN aware router to route traffic between segments and that will generally be the bottleneck.
I hope you aren’t planning on buying any of those modules you linked to in your post. Those are all… strange things, but WILDLY expensive. They are probably close to ISP-grade rack switch modules, which is NOT something you would need for yourself.
Just look for 10 or 20 dollar network switches that advertise 1 Gbps. That should be easy to do. In fact, I’d expect older 10/100 switches would be MORE expensive to buy, since they probably aren’t manufactured any more.
Keep in mind that, depending on your house network, you may need to upgrade more than 1 switch. Track the signal from your server to your clients. Every time it enters a switch, check that they are a gigabit, and note that down for an upgrade.
@kesawi brings up a good point, is that if any of your devices use wireless communication, then you may need to replace your router as well to one capable of higher speeds. But I’d like to know more before you just run out and buy and install a new router, because unless you are running an ancient router/modem, it’s likely already sufficient.
Networking is fairly complex, and without knowing your setup it’s impossible for us to make any concrete recommendations.
