Hi everyone, I have a network I am helping someone work on in an old house. The modem and router are on the 4th floor. There is a wire run from this router (its an uncommon brand) down to the 3rd floor and it goes into a jack there. I want to take that jack and plug in a Linksys WRT54G into it and use it so that the internet can be accessed from it on the 3rd floor. What else has to be done besides shutting off DHCP? It will be upgraded to HyperWrt or equivalent for power output increase.
