Mine seems a little vague on this front too.  To start with it doesn't 
show everything, then after a refresh it does.  The machine name for 
each device seems to be derived from Windows file sharing.  Machines 
running Samba show a name; machines not running Samba are "UNKNOWN".

All my machines except one use DHCP.  The one which doesn't is the DHCP 
server.  They all show up in the list.  Some are wired and some use WiFi.

Do you mean none of the machines on the LAN can communicate with any of 
the others?  If so it doesn't sound like you have a working LAN.  If 
not, is there a particular machine which can't see any others?

AFAIK, to your LAN the Netgear box functions just like a switch, which 
IIRC means it doesn't do ARP at all.  I've had a couple of glasses of 
wine, and it's been a while but as I remember it the ARP protocol runs 
between the two communicating computers.  The switch's job is just to 
pass on packets as appropriate.

Please clarify your statement that your machines can't contact each other.

Cheers,
John
