Connection is lagging Speed is reduced Network performance is affected
Recently, I purchased a TP-Link Archer TX3000E Wi-Fi card for my Jellyfin/NAS setup. Unfortunately, a wired link isn’t available because I relocated it to a quieter area of the house where the HDDs can operate without noise. However, I encountered some issues recently. After spending time on piracy, the network on that PC began to falter significantly. Remote Desktop connections kept dropping. After several attempts, I performed speed tests and found that my download speed was decent, but upload speeds were only about 10% of normal. On a wired connection, performance remained at the advertised 400/25 Mbps. I also ran iperf3 tests; while UDP results were satisfactory, TCP performance showed noticeable drops, sometimes reaching zero or well under 100 Mbps. After restarting my router (Cudy WR3600E), the problem temporarily disappeared, but it reappeared later. Since the wired network still functions properly, I suspect the issue lies with the Wi-Fi card or related driver/Windows settings. I also forgot to verify speeds on my phone to determine if the problem was PC-specific or router-related. Have you ever faced a similar situation? Do you have any suggestions on resolving it? I’ll attempt to recreate the issue and test with other Wi-Fi devices.
Are you continuing to distribute those Linux ISO files? Did you set a bandwidth restriction? It’s possible your router is automatically managing QoS, which might prevent other devices from experiencing problems.
On my Linux system the QoS settings are currently blank. I’m trying to verify this by using my phone on the router, which showed maximum performance even when connecting via WiFi—RDP also worked fine. It seems the problem might be specific to that setup rather than the router itself.
It looks like a possible driver problem. In Device Manager I selected restore previous driver, which brought it back from the newest AX200 driver from Intel’s site to an older version from early last year. It fixed the issue right away, but after a short download period it reverted again. Tomorrow I’ll capture a screen and test the latest driver from TP-Links after uninstalling the current one. The software is from 2023, though there could be reasons why only that year’s version appears.
It's often due to vendors not wanting to spend time updating it.
