i've reimaged it already as you said.
i had my laptop connected on wifi and an ethernet cable plugged directly into the pi
then i had the ipv4 network connection settings of the laptop forcing the static ip of the laptop to be 192.168.0.101
even after doing this i could not ping or browse the IP of the raspberry from the laptop..
i made this post on openwrt forum.. https://forum.openwrt.org/viewtopic.php?id=70801
