BTW.....
I'm assuming when you say "ethernet linksys" you mean it's a cable router?
If so to clarify...
Ignore the cable (WAN) port on the lynksys all together and use the normal LAN ports to connect the two together, before doing this though, connect a computer to one of the lan ports on the lynksys, preferably set the computer to a static IP in the range the lynksys allocates, log into the lyncsys setup pages, firstly disable DHCP, then optionally change the IP address of the lynksys router to one in a different range than the netgear (you'll loose connection to the router as this point)
Then simply connect the two together using a ethernet cable (again using the LAN ports, not the WAN port!), make sure you put the computer back onto obtain IP address automatically and connect it wireless, the netgear will then supply DHCP and will be set as the gateway and the lynksys will just act as a wireless switch.
Connecting them using the WAN port on the lynksys without making any changes would result in getting double NAT, which although it would appear to work would cause problems with some services (such as VOIP)
