OpenWRT's base install provides /bin/ping. It doesn't support -n -i .2. As recommended in the README, installing iputils-ping provides /usr/bin/ping which supports -n -i .2. Unfortunately, in some OpenWRT contexts, PATH has /bin before /usr/bin, and openpyn is slooow to connect. This is the case within LuCI's custom-commands, for instance. I'm working around this issue by redefining PATH in custom-commands to search /usr/bin first doesn't seem to have any ill side effect. Leaving this note in case other OpenWRT uses have this problem.
