Bizarre setup yes, but there's a reason. Tried searching for answers, but can't seem to find a setup similar to mine. My boat is moored some distance from a marina Internet Wifi signal, so I use a Cantenna with a getto connection to the Airport Card on my PowerBookG4 OS X10.5.8. Works fine, but I'd like to share that internet connection through the MacbookG4 Ethernet Port to another Wifi router so I can connect my iPown or another computer locally. "Preferences>Sharing>Internet Sharing to computers using Ethernet> Wifi router WAN port" returns the dreaded Error Message: "Airport has a self-assigned IP address and may not be able to connect" Using DHCP - 169.254.72.144 I know my wifi router works fine, since it checks ok if connected directly to an ethernet port on the main internet connected Wifi router. I've tried a few. I've tried a few Manual port configurations, but don't really know what I'm doing. The D-Link Air Di514 802.11b router IP:192.168.0.1 has been reset to factory defaults after many restarts of both computer and router. Any suggestions?
