Consistent latency increases in networked applications (Ethernet)
Here are your details rephrased:
- Your PC specifications include a Ryzen 3700X with Sapphire Blower cooler, 5700XT Gigabyte X570 gaming motherboard, G.Skill TRIDENT 16 GB RAM at 3000MHz, Corsair 750W CPU cooler, Samsung 860 EVO Wi-Fi card, and a Western Digital 1 TB NVMe SSD.
- You recently performed a full system reset, which resolved blue screens, black screens, and high temperatures.
- Your router is located two rooms away, and because you don’t have Wi-Fi on the motherboard, you’re using a D-Link A2 2000 Gigabit network extender with two devices connected—one in the router and one near your PC.
- You’ve run CMD diagnostics on your IP addresses, but no issues were detected.
- You’ve updated all BIOS/UEFI drivers according to the manufacturer’s recommendations.
Powerline isn't the most effective solution. It might work in perfect conditions, but because many people aren't familiar with their home wiring, it often leads to frustration. You could suggest that 5.0GHz Wi-Fi provides a smoother gaming experience in specific situations. If this is the issue, you might attempt connecting the adapters to different lines on separate breakers, though further alternatives may be necessary.
