Hi,
I have been using freebsd as my primary OS on my ACER laptop for many years
now.
My laptop has 802.11AC card for which there is no kernel driver available. I

use a USB wifi adapter to access the wifi router.
I am having sporadic DNS failures .
After reboot, everything works fine but after some time (30 minutes to a
couple of
hours), Internet
connections start to fail.
When this happens, I am able to ping 1.1.1.1, my DNS server.
However,
# drill yahoo.com (or any other name) fails with following error:
Error: error sending query: Could not send or receive, because of network
error
Other devices connected to same Wifi router continue to work fine.
I ran drill under truss and it appears after sendto to 1.1.1.1, no response
comes.
After this error occurs, it stays like that for many some time (20-30
minutes) and
sometimes it gets resolved by itself.

Can someone please help me debug this problem?
I'm going to suggest that this might be a symptom of your usb port/hub
hanging-up/
disconnecting due to inactivity. Your BIOS setup may have a setting
associated
with that. OTOH I don't know what NIC driver you're using for your USB
network
adapter. When you discover you can't perform DNS lookups, are you still
associated?
eg; does the output of ifconfig still show associated? What are the settings
in rc.conf(5) related to your network setup?
Thanks,
