Just to clarify, the WAN or INTERNET ports on these small gateway routers (wired or wireless) are in fact just another name for UPLINK ports. same thing. it's just a matter of finding out if a deivice like a cable/dsl modem, a PC or another gateway/router or switch is a DCE or DTE deivce. no matter though.
you have a couple of options here......you can either do the above. just link the new wireless gateway/router to the old wired one from lan port to lan port. or, the easiest way would be to connect the wireless gateway/router's WAN port to that of the wired one's LAN port. you can set both of them as a DHCP server....won't matter. Your wireless device will obtain an external address from the wired router and the wireless computers will obtain addresses from the wireless router. in any case....they will all be able to reach the internet. Accessing file and printer shares will be more difficult if you go the second route. again.....just depends on what you are after....internet sharing, file/print sharing or both.
