I have found solution for lagging ssh which work for me. It was tested only on the latest available realsese Nightly 4.10.1 (https://www.armbian.com/donate/?f=https://dl.armbian.com/orangepizero/Ubuntu_xenial_dev_nightly.7z). The procedure is following.
1. Set your wifi connection with network manager (nmtui-connect).
2. Add following to the rc.local
GATEWAY=`route -n | grep "^0.0.0.0" | tr -s " " | cut -f2 -d" "`
ifconfig wlan0 down
ifconfig wlan0 up
route add default gw $GATEWAY wlan0
3. Change in rc.local
#!/bin/sh -e
to
#!/bin/bash
Make schure that NetworkManager-wait-online.service is enabled
