   Thanks for noticing that, Dave!  My approach to configuring these has   
   been "start with sensible values, and if that doesn't work. try changing   
   things until it does." :-)   
      
   Let's see... my printer (just reconfigured a few days ago) reports   
   	IP Address: 192.168.1.33   
   	Subnet Mask: 255.255.255.192   
   	Def. Gateway: 192.168.1.13   
   	Syslog Server: 192.168.1.13   
   (that last one was a total guess on my part when I entered it).   
      
   The router (configured a while back) has these entries (all changeable)   
   on its "Private LAN Configuration" screen:   
   	Private LAN DHCP Server Enable is checked   
   	Private Lan Enable is checked   
   	Modem IP Address is 192.168.1.13   
   	Subnet Mask is 255.255.255.192   
   and then for "Private LAN DHCP Settings" it has:   
   	DHCP Start Address is 192.168.1.16   
   	DHCP End Address is 192.168.1.47   
   	DHCP Lease Time is exactly one day.   
      
   So both (like both computers) report a netmask of 255.255.255.192   
   (that's 255.255.255.0/27, right? or is it 255.255.255.255/27?).  I   
   forget why I gave the DHCP start and end addresses those values (maybe   
   to avoid clobbering the broadcast address), but a few days ago when I   
   didn't have static IPs for the computers set up yet, it was handing out   
   IP address starting at 192.168.1.47 and descending from there.  I do   
   remember choosing a netmask of 255.255.255.192 because this is only a   
   small home LAN with only a few things on its network.  So... what did I   
   do wrong, and where?  What would you recommend changing?   
      
   Thanks again for taking the time to look through my post!  As part of   
   configuring my new system, I copied over the   
   /etc/pm/sleep.d/50-lm_sensors that you'd written about two years ago.   
   Oh... and Happy Canada Day to you!
