Turn your openwrt router into a bridge
So here is what I wanted to prevent a cable between our cablecom connection, where our first router is located and our office.
+---------+ +--------------+This graphic and most of the configs are from http://wiki.openwrt.org/WirelessBridgeWithWPAHowto I just changed it to match WPA1 and my WRT54g. This Script will turn your router into a wireless bridge, but with an IP on the LAN and on the wireless side assigned so you can still configure it.
| OpenWRT | <--- WPA secured WiFi ---> | Existing |
| bridge | | access point | -- (DHCP server)
