I've attached 5 minutes of pinging the wifi gateway, highlighting when the network freezes: ping-output-rtl8814au.txt
I don't want to spoil the fun, but it's usually a 3s to 4s freeze every 10-15s:

During this test, the system was really quiet (99.9% idle!):

And I've also attached 5 minutes of the same ping when using another USB Wifi adapter (TP-LINK TL-WN823N, which doesn't exhibit any network lag): ping-output-using-other-adapter.txt with this rtl8192cu (2.4GHz) the latency is better than with the rtl8814au at 5GHz!
Well I feel embarrassed: after a reboot the ping to the wifi gateway became normal (still high latency at 2ms though) and the network lag were completely gone. I had an uptime of about 2 weeks, working everyday 8h work on the machine. If it reappears I'll know what to do!
So if it happens to you, it's time to reboot!
I'm having the same issue, reboot didn't help. On W10 same adapter works fine, have no idea why it's happening
The network freezes for a few second or two every 10 to 60 seconds, the delay between the freezes seems random.
It's really annoying when editing files remotely as the keystroke has no effect for a few seconds.
This is what I've tried:
rtw_switch_usb_mode
: freeze occur in USB2 and USB3Details:
