You probably didn't get any answer because this is a very uncommon
situation but you didn't give any details about your configuration.

It certainly sounds like there's something wrong with your fping, and I
think fixing it is a better approach than looking for alternatives. Does
it work as badly from the command line too? Did you compile it yourself
or is it supplied by your OS vendor/distribution? Which version is it? What
platform are you running on? Does the packet size affect the loss?

There's no plugin for a "standard ping", as far as I know, but fping is
generally much better than those.
