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.
