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.
How many networks are in your neighbourhood?
ifconfig wlan0 list scan
will tell to some degree.
/bz
Here are some system information. I've tried changing a few tunables but
nothing changed.
