I need to be able to do DHCP address reservation on my WRT54G ver 8 router. Is there any third party software or upgrades that is doing this. I have a scanner that scans to IP Address, 6 laptops that travel, and the work WRT54G. When the laptops connect to the work WRT54G I need it to handout the same IP Address to each laptop each time. They just purchased the WRT54G so I hate to tell them to buy a different router.
