Yes
arpwatch (IPv4 only) addrwatch (both IPv4 and IPv6)
This also occurs when they use a router as a second access point instead of an Access Point only because a single function access point is more expensive.
My network rule: one router ONLY. Don't expect a router to stay acting as an access point only, regardless of what you configure it as. One power hit and/or one telephone tech support telling the customer to press the reset button can cause havoc.
