--- Comment #3 from Joseph Mingrone <j...@freebsd.org> ---
I've also seen it take longer to establish a connection after upgrading to 11.
This is on a Lenovo X220 and a T530.
We have switched to the 5 GHz band at home, but I recall testing with all
things the same as before the upgrade and still seeing the problem.
Once the connection is established it is stable [1].
Here is partial output from /var/run/dmesg.boot on the T530:

[1] As an aside, at work, the wireless network uses WPA-EAP. Before 11, the
connection would drop so often it was not usable, but things seem to have
greatly improved in 11. Thanks!
