Netgear Nighthawk 5ghz WiFi not uploading files
I have seen multiple threads about CAX80 Netgear Nighthawk not allowing people to upload files on 5g WiFi, I am also having this problem. I recently “upgraded” my modem to this device. I am only able to upload files on 2.4g. If I turn on my VPN, then I am able to upload on 5g. I can’t just run on 2.4g because the speed is awfully slow and downloading files takes a bit of time. I handle about 50 files a day downloading, then uploading. Switching back and forth is not productive at all.
Does anyone have a solution to this issue?

I was having the same problem on both my 2015 MacBook Pro and my 2022 Mac Studio M1 Max. On both devices, upload speed tests indicated fast speeds, and uploading files via gmail was fast. The issue was happening with file attachments on both Slack and Apple Mail on both devices. Anything over ~80kb would fail.
As to FURRYe38's questions:

In short, I had AX mode enabled; turning it off fixed the problem for me. I included the other info in case it helps someone else.
