RAX70 WiFi speed extremely slow, but download is normal. This is happening on MSI Codex ZS Gaming Desktop using Intel Wi-Fi 6E AX210 160MHz adapter with Intel driver version 22.140.0.3 from 04/26/2022. Router is located 12 feet from computer.

When running a speed test wireless results are 358.72 Mbps down and 1.10 Mbps up and 24 ms ping. Charter/Spectrum service of up to 400 Mbps down and 20 Mbps up. This is only happening on the desktop computer wifi. iPhone sitting on desk with desktop computer also tested wifi speed, results: 451 Mbps down and 23.6 Mbps up and 29 ms ping. (This is what speeds should look like)

Does anyone how to remedy the poor upload over wifi on desktop computer?
