[NBLUG/talk] [OT?] Static DHCP leases from a LinkSys router?

Others beat me to responding, but I figured I'd reply anyway.  I had 
this same problem with my WRT54G router - my MythTV server address kept 
changing, which was a problem. The easy solution is to specify a static 
IP in the range of through instead of having 
your system / server use DHCP.  The IP address is always the 
router and addresses above are reserved by the router for 
DHCP-assigned IP addresses, so you'll want to avoid those.

If the systems you're using need to move on and off of the network and 
need to stay on DHCP, your only other option is to upgrade to a 
WRT-based router that can handle Open-WRT so you can set up a rule to 
assign specific addresses based on the MAC in use.

Best of luck,
