For what it is worth, lagg(4) for wired- and wireless connections works
fine for me.

In my network, wireless and wired setup is done from a FreeBSD firewall
with an em(4) and ath(4) device configured as a bridge(4) interface.

I have the following scripts that handle the lease renewals:

  --- /etc/start_if.lagg0 begin ---
  #!/bin/sh
  /bin/pkill dhclient
  /usr/local/sbin/dhclient -6 -lf /var/db/dhclient6.leases -pf \
    /var/run/dhclient6.lagg0.pid lagg0 2>&1 >/dev/null &
  /usr/local/sbin/dhclient -4 -lf /var/db/dhclient.leases -pf \
    /var/run/dhclient.lagg0.pid lagg0 2>&1 >/dev/null &
  --- /etc/start_if.lagg0 end ---

  --- /etc/start_if.lagg0 begin ---
  #!/bin/sh
  /bin/pkill dhclient
  --- /etc/start_if.lagg0 end ---

When I switch from wired to wireless or the reverse, there is a brief
connection loss (about 3 seconds).
