I'm living in an RV and using a DLink wifi router configured with DD-WRT firmware serving as my private, local network, currently on a DSL modem to get the ''outside world'.  Before that, I used to have a small DLink RE to pick up the RV Park's wifi hotspot, then fed that to t router through the cat5 cable.  That worked well, when the RV park wasn't busy (i.e. when I wasn't surrounded by those large executive coaches).  This pak recently upgraded  their WiFi with several repeaters (one is right across the roadway from my front door, only about 30', or 10m distant).  Now I want to ditch the DSL modem and set up my little network with a better range extender to use the park's WiFi, feed it to my Router, which then hosts all my local devices via WiFi.  I have all my internal stuff on my own SSID and a different range of IP addresses, to make sure my internal traffic doesn't go through the park's router, and I want a setup that I can move to another RV Park if I need to..

Now, I've forgotten what settings I need to make on this RE to make it work.  Anyone have any suggestions?
