I’m trying this out now. You get the idea. At my previous home (that old router), I faced problems where my network would disconnect during YouTube streams. Now that I’ve switched things up, it seems the issue isn’t happening. However, I’m still figuring out whether reinstalling drivers is necessary now.
Sorry for the delay... I have Intel RST turned on on my Mobo to use Intel Optane with my HDD. I'm encountering an error when trying to boot from the USB drive. I was planning to try a different method but it's a bit too late now. Maybe tomorrow I'll figure something out. By the way, I checked my speed again since then—it doesn't consistently reach 400-500 Mbps, only briefly hitting 600 Mbps. I'm not sure what's going on, possibly a Windows update... since I moved this weekend. Uncertain.
Use the Intel LAN port and turn off the Killer Control Center if possible. Have you installed the latest drivers for the Intel LAN chipset? What speed does Windows detect in the network adapter settings? Is the gateway applying any QoS rules? During testing, are there other devices or resources using bandwidth simultaneously? What is the model of this switch? Have you connected the PC to a different port? Would you like to run iPerf between the affected PC and another that doesn’t have the problem? What results do you observe?
Disabled the malfunctioning Control Center and upgraded the Intel Lan Chipset for the Mobo. - No adjustment Link speed remains at 1.00 Gbps Full Duplex. Auto negotiation isn't available on my gateway. Streaming is active, but I tested on two different devices to achieve better performance, including using Wi-Fi on my phone. I acknowledge that bandwidth usage could affect results, though it won't drop to a quarter of total bandwidth. The switch model is TP Link TL-SG1008P. Other ports, cables, and switches yielded identical outcomes, suggesting the issue might be on my end. For iperf data I received: receiver stats seemed unusual since the sender reported 1.09 GBytes each way.
The iperf outcomes seem satisfactory, suggesting the issue likely lies elsewhere. I considered QoS settings on the router as a potential cause. Since the network remains active during speed testing, it might help to see if performance improves when you’re the sole user. If you’re connected directly to the main router (around the TP-Link switch), does this affect results? Also, did you notice any changes in performance when other devices join the connection, especially those needing high bandwidth like VoIP or video calls? Regarding your PC, is it the only device using the switch? Could another device with similar speeds also connect through it?
I'm connected to a Cisco IP phone via the switch, which links to a computer with near gigabit speeds, and then to my PC. I've tested connecting my laptop via USB-C to Ethernet, which also gives gigabit speeds. However, the network usage seems inconsistent—sometimes it works perfectly, other times it's unreliable. When I go back to my PC, the speeds fluctuate unpredictably. The switch has QoS features, but it's unmanaged, so I don't think any adjustments are possible.
