Hello,
I have an RTL8812au card on FreeBSD 14.0-STABLE and the connection is
very unstable.
For example, when downloading packages with pkg, the download rate goes
down to 0
for a few seconds, then goes up not above 2MB/s for a few seconds, it's
often under 500KB/s
and often does not last longer than a second or so, then goes back to 0
for a few seconds.
I haven't felt this instability when browsing the web or pinging, it
seems to happen during longer connections.
Here are some system information. I've tried changing a few tunables but
nothing changed.
