On my home network I have 2 routers.
The main one connects to the Internet the other merely extends the network as the main only has 2 ethernet ports!
Home Network sees the 2nd router as an uknown device.
I used Edit Details to describe it as a Router and give it a name.
This information doesn't seem to stick across a reboot.
This isn't really an answer, but the symptom is discussed -among others- on this thread > http://community.mcafee.com/thread/21993
Basically, it appears to be a known bug, and they're working on it.
