I'd be willing to try the new firmware as well Fraser if you're willing to send it. Thanks so much for all of your tips troubleshooting too. I appreciate it.

I'm not using armor. I read elsewhere that it can cause issues and I don't need it so I deactivated it.

I don't have any custom rules in traffic prioritization. I monitored while running a speed test and it is not being categorized as gaming data packets. Just to be sure I deactivated the default gaming packet prioritization and the upload speed is still able to exceed the congestion threshold on wifi.

Disabling AX in both the wireless setup and advanced wireless setup did not resolve the issue.

I don't see that option anywhere in the advanced wifi settings. I see settings for explicit beamforming, MU-MIMO, and Enable AX. All of which are currently turned on.

Thank you for the warm welcome. I'm not using IPv6, VLAN, or PPoE.I have a normal IPv4 residential cable internet connection. I have a simple modem plugging directly into my XR1000 router and no additional networking devices on my network. My network only has one wired device, which is my PC, and all other connections are wireless 2.4 or 5 ghz. I've tried all of the remedies mentioned earlier in this thread to no avail. My wired device obeys my congestion control settings for both upload and download at all times, but my wireless devices on both 2.4 and 5ghz don't obey the congestion control setting for upload. They do however obey my congestion control setting for restricting download speed. I've double checked and I am on the latest software version available.

Just confirming that I have observed the exact same behavior that the OP outlined which is quite disappointing as I don't have a lot of upload bandwidth and I need to be able to limit it to prevent buffer bloat.
