Every Now an then my Endpoint protection keeps addressing a Mac Spoofing threat

it reads "Unsolicited incoming ARP reply detected, this is a kind of MAC spoofing that may consequently do harm to your computer" ive done a few tracert reports and didnt see any alarm there.  I am also on a wireless network and my question is could this be the network im on "bridging" trying to find my IP address causing the Message above? and should this be any concern for alarm?
